Cardiac Output

Overview

Cardiac output (CO) monitoring enables you to evaluate the patient’s fluid status

and the pumping ability of the heart, as well as calculate and display various

hemodynamic values.

Cardiac output is calculated by the thermodilution technique using a variation of

the Stewart-Hamilton formula. Thermodilution involves injecting a cooled fluid

(injectate) through a flow-through housing into an intravascular catheter. The

catheter delivers the injectate directly to the right atrium and monitors the

temperature downstream from the delivery site at the pulmonary artery.

Cardiac output is determined by measuring the change in blood temperature

downstream from the delivery site with respect to time. The change in

temperature is inversely proportional to the flow of blood through the right heart. If

the flow is large, the volume of blood that the injectate mixes with is large as well,

so the monitor detects a small change in temperature. When a smaller flow of

blood is diluted by the same volume of injectate, the change in temperature is

larger. The injectate has a larger influence on the temperature as measured in the

pulmonary artery.

The system displays cardiac output by plotting a curve for each injection. The

vertical axis of the curve represents temperature and the horizontal axis

represents time.

Spacelabs Medical’s cardiac output monitoring automatically captures vital sign

values at the moment each CO curve is completed. This data is used to produce

hemodynamic calculations.

Setup Procedure

The setup procedure that follows assumes that the pulmonary artery catheter has

been placed. Follow your standard hospital procedure to properly place the

pulmonary artery catheter in the patient.

Figure 19-1 illustrates the components used for CO monitoring. When using a

reference solution injectate temperature probe, it should be inserted into the

cardiac output cable in place of the in-line injectate temperature probe.

When you connect the thermistor connector port of the catheter to the cardiac

output cable, the system monitors patient blood temperature (TB) and displays the

value on the screen. When you connect the injectate temperature probe, the

system detects the temperature of the injectate (TI) and displays it on the screen,

but does not trend the data. The system displays a message instructing you to

connect the probe or catheter, or to enter the computational constant (CC).

If you connect the cardiac output cable only to the catheter or only to the injectate

probe, you can enter or adjust the computational constant but you cannot monitor

cardiac output.

To set up the system for

monitoring cardiac output:

1Insert the cardiac output cable

into the module.

2Attach the thermodilution

catheter to the cardiac output

Entering the Computational Constant

To generate calculations, you must first enter the computational constant (CC)

and verify that the system is correctly configured. Refer to your thermodilution

catheter package insert for current constants.

The temperature of the injectate changes due to contact with the catheter wall and

the surrounding blood. To account for this interaction, the system includes a

correction factor in the equation. The correction factor (K or CT) is a function of

catheter and flow-through housing dimension, internal volume, and injectate

temperature and differs among catheter models and manufacturers.

Once you enter a value for the computational constant, the value is displayed on

the CC= key and remains in system memory. Until you enter the computational

constant, the message CC REQUIRED is displayed, and ENTER

COMPUTATIONAL CONSTANT is displayed on the message line after the CC=

key is selected.

Entering Patient Height/Weight

To perform indexed hemodynamic calculations, you must enter the patient’s

height and weight before you generate CO curves. CO uses the patient’s height

and weight entered during the admit function.

The valid range for height is 10 to 85 in (25 to 215 cm). The valid range for weight

is 2 to 400 pounds (1 to 180 kg). After you enter both height and weight values,

the system automatically calculates and displays the patient’s body surface area

(BSA).

Measuring Cardiac Output

To maintain the accuracy of the readings, you must allow the catheter to warm up

between injections. When in AUTO mode, wait until the INJECT WHEN READY

message appears between injections. When in MANUAL mode, wait until the

TOUCH START THEN INJECT message appears.

Five curves can be displayed at one time. Some curves may automatically be

classified as “bad,” in which case they are then labeled BAD CURVE and are

automatically excluded from averaging. CO curves are numbered consecutively

from 1 to 99.

A 15-minute timer begins after acquisition of the first good curve. After

15-minutes, the AUTO/MANUAL and START keys become invalid (dotted), and

the messages MUST SELECT CURVES, AVERAGE, STORE, or CLEAR CO

appear. Cardiac output injections are disabled until you perform one of these

actions. Injections may resume as soon as the INJECT WHEN READY or TOUCH

START, THEN INJECT message appears.

• To obtain all hemodynamic calculations remember to enter

height and weight, and to store a PCWP prior to initiating

measurement of CO.

To enter the computational

constant:

1Touch CO.

2Touch CC =.

3Touch the appropriate keys

(tenths, hundredths, and then

thousandths) and use arrow

keys to adjust.

4Touch ENTER.

To enter patient height and

weight:

19-7

Averaging Cardiac Output

This function computes the average using the data from up to five, good,

displayed curves. Curves labeled as “bad” are not included in the average.

You can perform cardiac output averaging as soon as the system has measured

and displayed at least two acceptable curves.

When the cardiac output averaging is complete:

• The CO zone displays the curves used in the average, the averaged cardiac

output, and cardiac index values.

• The time and date of the last curve displays.

Clearing Cardiac Output Curves

Occasionally you may want to delete a curve prior to averaging or storing. All

curves, or only selected curves, can be cleared. If a “bad” curve is displayed when

you select to average, store, or clear another displayed curve, the “bad” curve is

also cleared.

When you clear an individual CO curve or all CO curves, the INJECT WHEN

READY message is displayed in the first available curve position, so the curves

displayed on the screen may not appear in numerical order.

Storing Cardiac Output Curves

This feature enables you to store all of the acceptable, displayed curves at once

or individually. The system stores the vital signs and cardiac output value it

acquired at the end of curve acquisition, along with the time it displayed each

curve. The curves clear from the screen as they are stored. The system does not

store “bad” curves. After you store the acceptable curves, the system clears all

curves from the screen.

Stopping Curve Drawing and Acquisition

This feature enables you to stop the curve drawing and data acquisition of a

cardiac output curve in progress. The STOP CURVE key only appears during

curve drawing. Touching this key will invalidate all curve data for that injection.

Once the blood temperature is again stable, the INJECT WHEN READY message

will appear if in AUTO mode. The TOUCH START THEN INJECT message will

appear if in MANUAL mode.

To average all cardiac output

curves:

1Touch CO.

2Touch CARDIAC OUTPUT.

3Touch AVERAGE ALL.

4Touch YES.

To clear or store all curves:

Selecting Index Normalization

To individualize the values to the patient, the system calculates them with the

BSA. Cardiac Index (CI) and Stroke Volume Index (SVI) are automatically

displayed.

You can display either the Systemic Vascular Resistance (SVR) and the

Pulmonary Vascular Resistance (PVR) or their indexed values (SVRI and PVRI),

but not both simultaneously. Similarly, you can display the Left Ventricular Stroke

Work (LVSW) and the Right Ventricular Stroke Work (RVSW) or their indexed

values (LVSWI and RVSWI), but not both simultaneously.

Displaying Cardiac Index and Cardiac

Output Values

The cardiac output or both cardiac output/index values can be displayed with the

curves. If the CO portion of the CO|CO/CI key is highlighted, only the cardiac

output value will be displayed. To activate the display for the cardiac output and

cardiac index values, touch the CO|CO/CI key to highlight the CO/CI segment. If

the cardiac index value is available, then it is displayed when the CO parameter is

inactive.

To select indexing:

1Touch CO.

2Touch CARDIAC OUTPUT.

3Touch CALCS.

4Select VR INDEX ON or

SW INDEX ON.

To display both cardiac output

and cardiac index values:

Displaying Calculations Table

You can view hemodynamic calculations after storing or averaging data. The table

includes only those calculations that have been stored or averaged.

Table 1 shows an example of the hemodynamic calculations table displayed when

you touch the CALCS key. Each horizontal row is one complete set of data. Each

new value appears at the bottom of the table. The system defaults to VR INDEX

OFF and SW INDEX OFF.

The system automatically calculates and enters CO and CI values in the table.

Values in the columns SV, SVI, SVR, PVR, LVSW, and RVSW are automatically

calculated from the vital sign values entered in the columns HR, MAP, CVP, MPA,

and PCWP.

The values under the columns HR, MAP, CVP, MPA, and PCWP are parameter

values obtained from other channels in the bedside monitor at the time a CO

value is calculated or those values you have entered manually. To enter values in

these columns refer to Editing Vital Sign Values on page 19-10.

If you do not enter height and weight values prior to generating CO curves, the

monitor displays any value that uses BSA (e.g. CI, SVI, LVSWI and RVSWI)

as ?.?. If a calculated value is out of the displayable range, the monitor displays

the value as ++++. If any of the vital signs in the hemodynamics table are

negative, the system uses the value 0 (zero) in the calculations.

The equations used for the hemodynamics table are defined in the table to the

left.

Editing Vital Sign Values

Select a row of data in the hemodynamic calculations table to turn the vital signs

keys ON.

Default values are supplied if you touch the VITAL SIGNS key and no prior value

is available. When you edit a value, the system recalculates the hemodynamic

calculation values using the new vital sign value.

A CVP value is used in calculations if it is available. If only a RAP value is

available, then the RAP value is used in place of CVP. If neither CVP nor RAP

pressure is available, the system cannot automatically calculate SVR, SVRI,

RVSW, or RVSWI. A CVP or RAP value can be manually entered using this edit

process.

A PCWP value is used in calculations if the last stored PCWP value is less than

15-minutes old. If no such PCWP value is present, an LAP value is substituted. If

neither PCWP nor LAP values are available, the system cannot automatically

calculate PVR, PVRI, LVSW, nor LVSWI and the monitor displays the message

NO PCWP VALUE AVAILABLE WITHIN THE LAST 15-MINUTES. You can add a

PCWP value manually using this edit process.

View Additional Table Data

Five sets of values display at any one time. Additional sets of values can be

displayed by scrolling through the data.

Thirty sets of values are saved in the monitor’s hemodynamic calculations table

so you can remove and re-insert the module without losing hemodynamic values.

You can erase these values by discharging a patient or by powering the monitor

OFF.

SvO2

Overview

Measurements of venous oxygen saturation (SvO2) provide a status indicator of

the oxygen transport system in the critically ill patient.

Low or rapidly decreasing saturation values indicate an imbalance between

oxygen consumption and oxygen delivery. Normal values reflect a balance of the

oxygen transport system or the patient’s ability to successfully compensate for

alterations in oxygen supply or demand. Continuous SvO2 monitoring can reduce

the frequency of additional invasive measurements and enhance the timeliness of

intervention in the critically ill patient.

This system utilizes three-wavelength reflectance spectrophotometry to sense the

amount of light absorbed by the blood. The use of three wavelengths

compensates for changes in light reflectance from red blood cell surfaces, blood

vessel walls, and for variations in hematocrit values. Digital filtering reduces

vessel-wall artifacts.

Data acquisition begins when an Abbott Opticath catheter is positioned at a site

within the pulmonary artery. The catheter connects to an Abbott Oximetrix optical

module which contains three LEDs emitting red and infrared wavelengths of light.

The catheter returns reflected light through a second optical fiber to the optical

module. Here the light is converted to an electrical signal which the SvO2 module

Setting Up SvO2Monitoring

In addition to the Spacelabs Medical module, venous oximetry monitoring requires

an Abbott Oximetrix 3 optical module with connecting cable and an Abbott

Opticath catheter. You must correctly connect all necessary cables, prepare the

catheter and patient for this invasive procedure, and calibrate the catheter to

begin monitoring.

The system provides two calibration methods. The patient’s current status

determines the proper calibration method. You can calibrate the catheter:

• while in its sterile package, or

• after it has been placed within the pulmonary artery, and you can verify

adequate light intensity during monitoring.

Refer to Preparing the Catheter on page 20-5 and Performing Pre-insertion (in

vitro) Calibration on page 20-6 for more details.

Preparing the Catheter

Each Abbott Opticath catheter is packaged in a sterile, disposable tray which

includes a disposable optical reference. Inspect the catheter tray carefully. If you

suspect damage to the tray DO NOT USE THE CATHETER.

Perform the catheter setup according to the instructions included with the

catheter. Setup instructions are included here as a convenience.

1. Peel back the outer wrap. Do not break the seal of the inner wrap.

2. Peel back the lift tab to uncover the optical connector at the end of the tray.

3. Pull the optical connector slightly away from the tray. Place the optical module

in the recess at the open end of the catheter tray.

4. Open the end of the optical module by pulling straight out in the direction of the

arrow (refer to Figure 20-2). The monitor will display an INSUFFICIENT LIGHT

message.

Figure 20-2: Placing the optical module into the catheter tray

Ultraview Care Network

20-6

5. Place the optical connector into the optical module with the word TOP facing

up. Close the module (refer to Figure 20-3).

Figure 20-3: Placing the optical connector into the optical module

6. With the inner wrap still in place, press down on the black optical reference at

the point labeled PUSH. Listen for a click.

The catheter is now ready for pre-insertion calibration. After you complete the

calibration, prepare the patient for catheter insertion.

Performing Pre-insertion (in vitro)

Calibration

This calibration procedure tales up to 72-seconds. When calibration is successful,

the message PRE-INS CAL COMPLETE displays and the event mark P displays

on the oximetry trend.

If the catheter fails calibration, verify the following:

• A secure cable connection exists between the optical and SvO2 modules.

• The catheter tip is inserted properly within the optical connector.

• You have pressed the optical reference with enough force to hear the click,

indicating a secure connection.

• You tested the catheter by replacing it with a known good catheter to ensure

proper catheter function.

Repeated calibration failure with a known good catheter may indicate a defective

optical module. Replace the optical module if necessary.

To initiate pre-insertion

calibration:

1Touch SVO2.

2Touch CALIBRATE.

3Touch PRE-INSERTION.

4Touch YES.

SvO2

20-7

Inserting the Catheter

Follow standard hospital procedure to prepare the patient for catheter insertion.

1. Using sterile procedures, peel back the remaining inner wrap from the catheter

tray. Pull the retainer (white tab) to release the catheter.

2. Grasp the catheter at approximately the 5 cm mark and gently pull it straight

out from the optical reference.

3. Prepare the catheter and insert it into the patient according to hospital

procedure. Oxygen saturation readings will immediately display on the

bedside monitor.

4. When the catheter is positioned properly, verify the light intensity signal is

within the correct operating range (i.e., the bars on the graph extend at least

two vertical dots within the high and low range markers).

5. Perform a light intensity calibration.

6. Begin continuous mixed venous oxygen saturation monitoring.

Performing Light Intensity Calibration

This procedure adjusts the optical module’s light intensity reference level to match

the light intensity returned through the catheter from the patient’s blood. The SvO2

module stores this value and signals an alarm if the detected light differs

significantly from the stored light levels.

Perform a light intensity calibration only when the catheter is in the proper position

in the patient.

CAUTION:

• The optical fibers can be damaged if you do not draw the

catheter out carefully.

• Do not begin a light intensity calibration if the signal is out of

range. If this occurs, refer to Correcting Out-of-Range Light

Intensity on page 20-11.

To initiate light intensity

calibration:

1Touch SVO2.

2Touch CALIBRATE.

3Touch LIGHT INTENSITY.

4Touch YES.

Ultraview Care Network

20-8

Performing In Vivo Calibration

In vivo calibration compares a drawn (measured) blood gas value with the value

displaying on the monitor. The catheter manufacturer recommends that the

oxygenation value be checked periodically. Several conditions may necessitate in

vivo calibration.

• Catheter was placed without pre-insertion calibration.

• Catheter has been in place for an extended period of time.

• Decaying light intensity values indicate possible damage to the fiber optics

(in this case, the catheter manufacturer recommends checking the

oxygenation value every 12-hours).

• You believe the saturation reading is incorrect.

Perform an in vivo calibration only when the patient’s oxygen saturation is

relatively stable and the intensity signal is within normal limits. When calibration

begins, the optical module stores the preceding 5-seconds of oxygen saturation

data.

Displaying Intensity Data

You can display a history of light intensity values superimposed over the

saturation trend graph. This combined display can be valuable for troubleshooting

because the quality of light passing the catheter tip directly affects the accuracy of

the saturation value. Successful monitoring ensures light intensity values remain

within the limits of the bar graph display.

Real time maximum and minimum intensity values display as vertical bars to each

side of a vertical row of dots. This display updates every 6-seconds. Horizontal

lines represent the recommended operating limits for light intensity.

Removing display of the intensity data does not affect storage of the data in

monitor memory, and the current intensity continues to display in the intensity bar.

Setting Alarm Limits

The current limits for venous oximetry display to the right of the parameter key.

You can set high or low saturation limits.

The alarm default is OFF. When you turn alarms ON:

• they default to a high of 80% and low of 60%.

• the exceeded limit key flashes.

• the limit value is displayed in the message area of the screen.

• Use only measured oxyhemoglobin saturation values from a co-

oximeter. Do not use values calculated from a laboratory blood

gas analyzer. Oxyhemoglobin values calculated on the basis of

PO2, pH, and temperature have been shown to be inaccurate.

To initiate in vivo calibration:

1Touch SVO2.

2Touch CALIBRATE.

point on the right side of the trend graph. As the module acquires new data, the

older data points move left to create a record of data.

Select Timebase

The SvO2module stores the most recent 16-hours of saturation trend data. You

can view this data graphically in 1-, 2-, 4-, 8-, or 16-hour time bases. Data is

displayed in 1-minute increments on 1- to 4-hour graphs, in 2-minute increments

on the 8-hour graph, and in4-minute increments on the 16-hour graph.

Select Scale

You can select one of three sizes for the trend graph:

•30% to 70%

You can use the calculations feature to obtain specific values for the oximetry

measurements listed below.

Arterial oxygen content — Ca

CaO2 = (1.34 x Hgb x SaO2/100) + (0.0031 x PaO2)

Venous oxygen content — Cv

CvO2 = (1.34 x Hgb x SvO2/100) + (0.0031 x PvO2)

Arterial-venous oxygen content difference

avDO2 = CaO2 - CvO2

Oxygen availability or oxygen delivery

O2AV = CaO2 x CO x 10

Oxygen consumption

VO2 = avDO2 x CO x 10

Values for cardiac output (CO), pulse oximetry (SpO2), and venous oxygen

saturation (SvO2) are automatically displayed when data is available in the

Ultraview Care Network system. You must manually enter laboratory values for

PaO2, PvO2, and hemoglobin (Hgb) to obtain calculations.

Printing Oximetry Data

You can print venous oximetry data in two formats: the current trend or the results

of the most recent set of oxygenation calculations. Refer to Printing on page 4-5

for more details on system and bedside printers.

Storing or Reading Data

The last 15-minutes of data gathered by the SvO2module may be stored in the

optical module’s memory before disconnection. That data can be read back into

the SvO2 module. The stored data includes the year, month, hour, and minute of

collection.

Correcting Out-of-Range Light Intensity

Each time you perform a light intensity calibration, the oximetry module stores the

intensity value and signals an alarm or error message if the current light level

differs significantly from the stored level. Light intensity error messages serve as a

reference to determine if the light at the catheter tip is adequate for accurate

monitoring. Do not ignore these messages.

The module alerts you to this condition when:

• an INTENSITY ALERT or SVO2 DATA OUT OF RANGE message is

displayed; or

• a second level alarm begins.

When the monitor displays the SVO2 DATA OUT OF RANGE or INTENSITY

ALERT message, select the intensity display feature to view a history of light

intensity values. Refer to Figure 20-4 to identify the type of abnormal intensity.

Refer to the following list of possible causes and solutions.

• High — check the position of the catheter as the tip may lie against the vessel

wall. Reposition the catheter according to your hospital protocol.

• Low, dampened, or erratic — check the blood flow past the catheter as a clot

may have formed over the catheter tip.

Figure 20-4: Abnormal intensities

Take the following actions:

• If a Spacelabs Medical invasive pressure module is being used, examine the

pulmonary artery (PA) pressure waveform for spontaneous wedge indicating

the catheter tip may lie against the vessel wall. If this occurs, reposition the

catheter.

• If a Spacelabs Medical invasive pressure module is being used for pulmonary

artery pressure monitoring, examine the pressure waveform for dampening,

indicating clotting over the tip of the catheter. If this occurs, follow hospital

procedure to flush the distal lumen. Reposition the catheter if necessary.

• Abnormal resistance when you push the catheter through the distal lumen

indicates damage to catheter fiber optics. Reposition the catheter and replace

if necessary.

• If connections between the catheter optical connector and the optical module

appear loose, tighten the connections.

• If the catheter contains obvious kinks, the optical fibers may be damaged.

Replace the catheter.

Ultraview Care Network

20-12

Correcting Insufficient Light Intensity

The message INSUFFICIENT LIGHT displays when an unusually small amount of

light is being received during monitoring or during pre-insertion calibration.

Take the following actions:

• If this message displays while the catheter is exposed to room light during

pre-insertion calibration, take no action. It disappears when the catheter is

placed in the patient.

• If this message displays during pre-insertion calibration while the catheter is

connected to the optical module, verify proper connection to the module.

• Check that the tip is fully inserted into the optical reference and firmly press

PUSH on the optical reference until you hear a click. Do not use the catheter

if the tip is pulled out of the optical reference when you receive the catheter

tray.

• Disconnect the optical module from the catheter, close the optical module lid,

and place the optical module in an area out of direct light. If the message

disappears, replace the catheter. If the message remains, contact your

system administrator.

• Examine the catheter for kinking. If optical fibers are damaged, replace the

catheter.

Correcting Calibration Errors

The message CALIBRATION REJECTED displays when pre-insertion or in vivo

calibration is not successful.

Take the following action as indicated:

• Check for secure catheter connection to the optical module. Reconnect the

catheter if necessary.

• Check the status message on the monitor screen to verify sufficient, stable

light intensity. If the INSUFFICIENT LIGHT message displays, refer to the

previous section which describes steps to correct this condition.

• Allow the optical module to warm up for one more minute, then retry.

The message NOT CALIBRATED displays and an alert sounds (if alarms are ON)

if you begin monitoring before you calibrate the system. The message disappears

after you complete a successful calibration.

Correcting Optical Module Errors

The SvO2module performs constant memory checks to ensure data is not lost or

changed erroneously. When the OPTICAL MODULE MEMORY ERROR

message displays, replace the optical module with a known good unit.

Expect the NO OPTICAL MODULE message whenever you disconnect the

optical module from the SvO2module because this suspends SvO2monitoring.

If this message appears when the optical module is not disconnected, replace the

module or contact a qualified service person.

SvO2

20-13

Correcting SvO2 Display Error

If the oxygen saturation value is out of the display range, the display changes from

a percentage to ???.

Take the following action as indicated:

• Verify proper function of the optical module; no error messages display.

Replace with a known good module if necessary.

• Display light intensity history to verify proper catheter function (refer to

Correcting Insufficient Light Intensity on page 20-12).

• Perform in vivo calibration.

Ensuring Catheter Function

The catheter fiber optics are sensitive to damage. Avoid kinking, excessive

manipulation, or grasping with forceps or a hemostat. Damage to the fiber optics

reduces transmission of light to and from the blood which significantly

compromises oxygen saturation accuracy.

Damage is indicated by one or more of the following:

• Low intensity display.

• Intensity error message displays.

• Intensity alarms begin if alarms are ON.

• Oxygen saturating values are inaccurate.

Capnography

Overview

The 90516 Ultraview Capnograph module is a mainstream gas analyzer,

designed to measure the concentration of carbon dioxide in a gas mixture to aid in

determining the patient’s ventilatory, circulatory, and metabolic status. The

capnograph module has a small, lightweight sensor that continuously measures

the end-tidal and minimum CO2 levels in the patient’s airway. Respiration can be

monitored via airway and endotracheal or tracheostomy tubes. Both adults and

neonates can be monitored with this type of capnograph (using separate adult

and neonatal airway adapters).

The sensor head contains a small infrared transducer that accurately measures

the CO2 in the airway. The sensor is connected to the airway by an airway

adapter. These adapters may either be disposable or reusable and are available

in adult and neonatal sizes.

The capnograph automatically compensates for the ambient barometric pressure

to ensure accurate readings. A connector is included to allow measurement of O2

in the airway using a fuel cell type O2 sensor. A full calibration menu is provided to

easily calibrate and use the O2 sensor. A separate adapter is used for O2

monitoring.

Ultraview Care Network

21-4

CAUTION:

• Although the 90516 capnograph module detects and

reports apnea conditions, it is not intended to be a primary

diagnostic apnea monitor and/or apnea recording device.

• Use only Spacelabs Medical sensors with this monitor.

Other sensors may plug in, but will not operate.

• Use only Spacelabs Medical airway adapters with

Spacelabs Medical sensors. The monitor may not function

if other airway adapters are used, and sensor damage may

result.

• If the patient’s airway is configured with a closed

suctioning system, make sure the airway adapter is placed

close to the suctioning system (on the ventilator side). This

will help ensure that the sampling adapter is not impaired

during and after suctioning.

• U.S. Federal law restricts this device to sale by or on the

order of a physician.

• If your module is equipped with the Module Configuration

Manager feature, you can define your own default settings for

such characteristics as alarm limits and display configuration.

Refer to Module Configuration Manager on page 7-5 for further

details.

Capnography

21-5

Patient Connection

Respiration can be monitored via an endotracheal or tracheostomy tube.

Mainstream capnography is a highly accurate method of measuring respiratory

gas values. There are several variations of closed circuit tracheal suction systems

that can be used with Spacelabs Medical capnography units. Spacelabs Medical

recommends the Ballard style tracheal suction system.

Closed Circuit Tracheal Suction Systems

Closed circuit tracheal suction systems (such as those provided by Ballard)

extend the life of the endotracheal tube and associated tubing by allowing the

endotracheal tube to be periodically suctioned without detaching it from the

ventilator circuit. Spacelabs Medical recommends use of Ballard Model #221

elbow closed tracheal suction systems, or similar systems, with Spacelabs

Medical capnography units. Such a system allows the Spacelabs Medical airway

adapter to be placed outside the tube through which fluids are being suctioned,

reducing the chance of occluding the airway.

Spacelabs Medical does not recommend use of traditional setups that require the

airway adapter to be in line with the endotracheal tube. However, if you prefer a

traditional setup such as the Ballard Model 2205 style, using the Ballard Model

112 adapter moves the airway adapter away from the suction catheter.

Figure 21-1 shows examples of setups using the Ballard Model #221 and Model

2205 style (with Model 112 adapter). Similar closed systems, such as the Concord

Portex (not shown), must be placed in the ventilator circuit in the same positions

as shown in Figure 21-1.

Display Detail

When you connect the capnography device to a monitor, the waveform area is

displayed in one of four formats, the large and small text formats in normal or view

alarms modes. Instructions for choosing a format are detailed later in this manual.

The full screen, large text format is the default display for bedside monitors. The

full screen, small text format in VIEW ALARMS is the only display format for the

full screen remote view monitors. The split screen central format is available only

for central monitors operating in split screen mode. Refer to Figure 21-2 through

Figure 21-6.

• Capnography is not analyzed during unit warm-up.

• The typical initial warm-up period is 2- to 5-minutes (5-minutes

is the maximum warm-up time). This time varies based upon the

temperature of the sensor.

• The capnograph is protected against the effects of a cardiac

defibrillation discharge and is safe to use on patients with a

cardiac pacemaker or other electrical stimulation.

• The airway adapter may require regular cleaning or

replacement if the capnograph is used on patients that emit

excessive mucous.

Setting Alarm Limits

You can set high and low alarm limits for respiratory rate (RR), EtCO2, O2,

minimum CO2 (high limit only), and the apnea alarm delay time.

When alarm limits for EtCO2 and RR are initially enabled, the limit values depend

upon the patient’s current readings for those parameters (these limit values are

learned). Alarm limits for all other monitored parameters, when enabled; always

have the same fixed values.

You can modify limits for any of the monitored parameters. Factory-set default

values appear for alarm limits when you initially power up the unit. Factory default

settings and ranges for alarm limits are shown on the table below. Refer to Alarms

on page 2-3 for additional information on alarms.

Calibrating the Sensors

Calibrating O2

A ZERO calibration establishes baseline values for the oxygen channel. You are

prompted to perform a ZERO calibration if it is required.

A room O2 span calibration calibrates the oxygen sensor using room air.

A 100% O2 span calibration sets the level for oxygen so that the display reads

100% when pure oxygen is input to the unit. For improved accuracy, a 100% O2

span calibration should be performed whenever the patient is receiving more than

60% O2.

• To minimize patient disruptions, perform O2 zero and span

procedures before the O2 adapter is placed in the ventilator

circuit.

• Authorized service personnel also use the 100% O2 span

calibration to calibrate the oxygen sensor’s response to

100% O2.

Calibrating the Airway Adapter

Adapter calibration compensates for the optical differences between the adult and

neonatal airway adapters. Adapter calibration needs to be performed each time

you switch from an adult airway adapter to a neonatal airway adapter.

Calibrating the CO2 Sensor

The CO2 sensor does not require calibration at each power up. Calibration is only

necessary the first time the sensor is connected, or when a CAL REQUIRED

message is displayed.

Once calibrated, the sensor can be unplugged and reconnected without being

recalibrated. However, a sensor calibration is required whenever the CO2 sensor

is changed.

• During calibration, keep the sensor and airway adapter away

from all sources of CO2 (including the patient’s and your own

exhaled breath, and ventilator exhaust valves).

• To maintain optimum performance of the sensor and

capnograph, you should perform a calibration verification of the

sensor at least once a week.

To calibrate the airway adapter:

1Touch GAS.

2Touch CAL.

3Select appropriate airway

adapter (neonate or adult).

Selecting Gas Compensation

The measurement of CO2 by infrared analysis is affected by the presence of

oxygen and nitrous oxide. The module must be set up with the appropriate

compensations turned on in order to obtain accurate end-tidal CO2 readings when

increased levels of O2 (greater than 60%), or N2O (greater than 50%) are present

in the airway.

Restoring Default Settings

With the Module Configuration Manager feature, you can restore all default

settings. User-configurable options are listed in Setting User-Defined Default

Values on page 7-7.

• High concentrations of O2 will cause a lower than expected CO2

reading.

• High N2O level will cause a higher than expected CO2 reading.

To select gas compensation:

Overview

The Spacelabs Medical Multigas Analyzer simultaneously monitors gas

concentrations and alerts clinical personnel when the concentration of anesthetic

agents, oxygen, carbon dioxide, or nitrous oxide falls outside of defined limits. The

anesthetic agent being administered is automatically identified.

The analyzer is for use primarily in the operating room, but can be used with any

Ultraview monitor.

Although the analyzer sounds an alarm when the duration between monitored

breaths exceeds user-defined limits, it is not intended to be a primary diagnostic

apnea monitor and/or recording device.

Warnings and Cautions

Warnings

The life or health of a patient, clinical staff member, multigas analyzer operator, or

other persons may be endangered if the items in this Warnings section are not

followed.

WARNING:

• Always test the sampling line adapter for a tight

connection and proper operation before attaching to a

patient.

• To protect the patient’s safety, do not silence, suspend, or

disable audible alarms without providing continuous,

direct observation of the patient.

• Connect the sample gas outlet on the monitor’s rear panel

to the scavenging system to prevent pollution of the room

air.

• Always turn the power off and unplug the analyzer before

cleaning to protect against electrical shock.

• To avoid explosion hazards, flammable anesthetic agents

such as ether and cyclopropane must not be used in the

analyzer.

• Only halothane (HAL), enflurane (ENF), isoflurane (ISO),

sevoflurane (SEV), and desflurane (DES) are suitable for

use with the analyzer. If any other halogenated anesthetic

agent is present, it will be misidentified and/or will interfere

with the reported anesthetic agent concentrations.

• The use of antistatic or electrically conductive breathing

tubes when using high-frequency electrosurgery

equipment may increase the risk of burns and is, therefore,

not recommended in any application of this anesthetic

monitor.

• The analyzer is not intended for use in an MRI

environment.

Multigas

22-5

Cautions

Equipment may be damaged or cease to function properly if the items in this

Cautions section are not followed.

CAUTION:

• When administering anesthetic agents, incorrect agent

identification may occur when a mixture of two or more

anesthetic agents occurs in the sample circuit.

• Always verify your vaporizer setting when administering

anesthetic agents.

• Use only original Spacelabs Medical sampling lines and

accessories; other sampling lines may cause inaccurate

readings and malfunctions.

• The diameter of the scavenging system line must be two to

three times larger than the sample line tubing to avoid

changes in the operating pressure of the monitor, and

consequential inaccurate readings or internal damage.

• Route the scavenger hose so that it does not kink during

operation of the monitor. A kinked or partially kinked

scavenger hose can impair performance of the monitor.

• If the patient’s airway is configured with a closed

suctioning system, the airway adapter must be placed near

the suctioning system (on the ventilator side). This helps

to ensure that the sampling adapter is not impaired during

and after suctioning.

• Do not use cellular phones or other wireless

communications equipment near the analyzer.

• Check the disposable water trap regularly during monitoring.

Replace the water trap when full.

• Between patients, replace the sampling line and check the

disposable water trap. Replace the water trap when full.

• The Spacelabs Medical sampling lines are for single-patient

use only. Cleaning deteriorates the properties of the sampling

line, resulting in slower response time and more frequent

occlusions

• Before you administer nebulized drugs to a patient that is

connected to the multigas analyzer, you must disconnect the

sample line from the patient or stop the pump by using the

SUSPEND SAMPLING key.

• To facilitate disconnecting and reconnecting the sample line,

use a T-connector in the patient airway circuit and keep the

sampling suspended, until all nebulized drugs have cleared

from the patient’s airway.

Multigas Setup

Before you put the unit into service, it must be unpacked and the exterior

inspected for visible damage. A biomedical technician or an authorized Spacelabs

Medical customer service representative should inspect the interior and exterior of

the analyzer for signs of visible damage. Instructions for these procedures are in

the 90518 Multigas Analyzer Service Manual (P/N 070-0643-xx).

Figure 22-3: Monitor connection

CAUTION:

• The diameter of the scavenging system line must be two to

three times larger than the sample-out tubing to avoid

changes in the operating pressure of the monitor, and

consequential inaccurate readings or internal damage.

• Route the scavenger hose so that it does not kink during

operation of the monitor. A kinked or partially kinked

scavenger hose can impair performance of the monitor.

To connect the multigas

analyzer:

1Verify that the power cord is

connected as required by local

standards.

2Assemble the cables

necessary for the desired

configuration. (Refer to 90518

Patient Connection

Respiration can be monitored via a nasal cannula, an oxygen mask, or an airway

and endotracheal or tracheostomy tube. There are several variations of closed

circuit tracheal suction systems that can be used with Spacelabs Medical multigas

units.

Figure 22-4: Example of sidestream multigas setup for an adult

The sample line must be connected to the disposable water trap and patient

circuit. Connect the line to the water trap prior to the insertion of the water trap

onto the analyzer to protect the sample port.

CAUTION:

• If the multigas analyzer is powered on before the patient

monitor, communication might not be initiated. Make sure

the patient monitor is powered on first.

• Use only original Spacelabs Medical sampling lines and

accessories. Other sampling lines may cause inaccurate

readings and malfunctions. The analyzer must use a

sample line that is fabricated from a special material. Use of

other sample lines results in erroneous readings. This

sample line is color-coded as blue and is available from

Spacelabs Medical.

• If you use the multigas analyzer with setups that do not

include the Spacelabs Medical approved gas analyzer

filters, and service inspection determines that patient fluids

have contaminated the unit, your warranty will be nullified.

• Use the filtered gas sampling tee when you operate the

analyzer on patients that emit excessive mucous. This prevents

patient fluids from clogging the sample line.

To start multigas monitoring

when the unit is OFF:

1Plug the device power cord into

an AC power outlet and assure

that the unit is connected to a

monitor.

2If not present, insert the gas

analyzer filter above the water

trap and close the lid.

3If not present, insert the water

trap with the patient connector

on the right side.

4Check to make certain the

Stand By switch is OFF (in the

“out” position).

5Turn power to patient monitor

ON.

6Turn power to gas analyzer ON

(ON/OFF switch on back of

unit).

7Prepare the patient according

to hospital procedures.

8Allow the analyzer to warm up

for a minimum of 2-minutes.

Full accuracy is achieved after

30-minutes.

9Connect one end of the gas

sample line to the gas sampling

tee or breathing circuit and

connect the other end to the

water trap luer connection.

10 Check for a good seal at the top

Prior to connecting to the patient airway, verify that there are no leaks in the

sample line, water trap, and gas analyzer filter by sealing the end of the sample

line with your thumb. After approximately 15-seconds, the Occlusion LED lights

and an occlusion message appears on the monitor. If this does not occur within

30-seconds, check for an air leak by removing and carefully reinstalling the water

trap, the gas analyzer filter, and/or the sample line. Repeat the test.

Closed Circuit Tracheal Suction Systems

Closed circuit tracheal suction systems (such as those provided by Ballard)

extend the life of the endotracheal tube and associated tubing by allowing the

endotracheal tube to be periodically suctioned without detaching it from the

ventilator circuit. Spacelabs Medical recommends use of Ballard Model #221

elbow closed tracheal suction systems, or similar systems, with Spacelabs

Medical capnography units. Such a system allows the Spacelabs Medical airway

adapter to be placed outside the tube through which fluids are being suctioned,

reducing the chance of occluding the airway.

Spacelabs Medical does not recommend use of traditional setups that require the

airway adapter to be in line with the endotracheal tube. However, if you prefer a

traditional setup such as the Ballard Model 2205 style, using the Ballard Model

112 adapter moves the airway adapter away from the suction catheter.

Figure 22-5 shows examples of setups using the Ballard Model #221 and Model

2205 style (with Model 112 adapter). Similar closed systems, such as the Concord

Portex (not shown), must be placed in the ventilator circuit in the same positions

as shown in Figure 22-5.

Operation

CO2, N2O, and anesthetic agents are measured by drawing a sample gas stream

into the measuring chamber. The absorption of different infrared light wavelengths

is measured here. These measurements are compared to a zero concentration

light level to calculate the different gas concentrations.

Oxygen concentration is measured using the micro-fuel cell sensing technology.

During the sensing process, the oxygen molecules in the sampled gas diffuse

through the sensing membrane and become reduced at the sensing electrode,

creating a current signal. The current signal is proportional to the oxygen partial

pressure in the sampled gas. The fast response of the oxygen measurement is

achieved by combining a unique design of the pneumatic sampling system, fast

sensing membrane, and state-of-the-art signal processing electronics. Because

this method of measurement has a fast response time, inspired and expired

values of O2 can be reported. This method of O2measurement requires periodic

replacement of the sensor. The user must perform routine calibration checks to

determine when replacement is needed. Refer to Initiating a Calibration on page

22-19 for further details.

The analyzer uses a side-stream sampling technique to acquire respiratory gases

from an endotracheal tube, nasal cannula, or mask. A constant-flow vacuum

system maintains the flow rate through the sample line.

The analyzer is equipped with an external water trap to prevent humidity, water

drops, and patient secretions from contaminating the unit or affecting the accuracy

of the gas measurements. The water trap collects water drops that condense in

the sample line. A “Water Trap Full” indicator warns you that the water trap should

be replaced. The analyzer is also equipped with a filter as a second line of

defense in case the water trap overflows or nebulized drugs are accidently drawn

into the sample line. After the gas sample passes through the water trap and filter,

it passes through a Nafion tube that is inside the analyzer. This helps to equalize

the humidity of the gas sample so that it is close to the humidity of ambient air.

WARNING:

• If any halogenated anesthetic agent other than halothane,

enflurane, isoflurane, sevoflurane, or desflurane is present,

it will be misidentified and/or will interfere with the reported

anesthetic agent concentrations.

CAUTION:

• When administering anesthetic agents, incorrect agent

identification may occur when a mixture of two or more

anesthetic agents occurs in the sample circuit.

• Always verify your anesthetic vaporizer setting when

administering anesthetic agents.

Multigas

22-11

The analyzer automatically compensates for the ambient barometric pressure to

ensure accurate readings. Both CO2 values may appear in partial pressure (in

mmHg or kPa) or in percent.

Powering ON the Unit

Before powering the multigas analyzer ON, make sure it is attached to a patient

monitor and the Stand By switch on the gas analyzer is OFF (in the “out” position).

Press POWER ON/OFF located on the rear panel of the analyzer. The patient

monitor must be powered on prior to powering on the analyzer.

When you first power ON a properly installed multigas device, the green power-on

LED lights within 5-seconds. Within 30-seconds the patient monitor displays the

vertical GAS parameter key adjacent to a flat waveform.

If this does not occur, verify that the POWER ON/OFF button is pressed and

appears green, and that the front panel STAND BY button is not pressed. The

analyzer must be connected to an AC power outlet. Verify that the appropriate

SDLC cable and terminator are connected from the unit to the monitor (refer to the

90518 Multigas Analyzer Service Manual, P/N 070-0643-xx). If the monitor or the

module housing has a SDLC switch, check that the switch is in correct position

(refer to the operations manual for the monitor or module housing). If the GAS

parameter key does not display on the monitor, turn the power to the analyzer

OFF, then turn the power to the monitor OFF. Power ON the monitor again, and

then power on the analyzer again.

CAUTION:

• The analyzer cannot be operated without a water trap and a

gas analyzer filter installed.

• Replace the water trap and gas analyzer filter as needed.

Verify the water trap is not broken as a result of connecting

the sample line fitting too tightly or by tugging on the

sample line. To verify, place a finger over the end of the

sample line and wait for the alarm. Check the sample line

connection on the water trap for damage. A broken water

trap results in low values due to room air entrainment. If a

span calibration is performed with a broken water trap,

patient values will be unusually high. Refer to Initiating a

Calibration on page 22-19 and Replacing the Gas Analyzer

Filter on page 22-12 for details.

• Check the disposable water trap regularly during monitoring.

Replace the water trap when full.

• Between patients, replace the sampling line and check the

disposable water trap. Replace the water trap when full.

No multigas analyzer data appears during the warm-up period following power-on.

Data first appears during the stabilization period.

Upon initiation of power, all factory-default settings will be re-established. Any

modifications made to the default settings (alarm limits, text display, etc.) prior to

cessation of power will be lost.

Replacing the Water Trap

The water trap must be disposed of when full. To remove the water trap, grasp the

water trap firmly and pull it down from underneath, then lower it from the

assembly.

To install a new water trap, grasp it from the bottom and insert it up and into the

assembly.

Replacing the Gas Analyzer Filter

The gas analyzer filter must be disposed of when occluded. To remove the gas

analyzer filter, lift the filter door, grasp the filter tab, lift up, and remove.

To install the filter, open the filter door, hold the filter by the tab (with the gasket

down) and place it into the recess. Close the door after insertion.

Display Detail

When you connect the multigas device to a monitor, the waveform area is

displayed in one of four formats, the large and small text formats in normal or

VIEW ALARMS modes. Instructions for choosing a format are detailed later in this

manual.

The full screen, large text format is the default display for bedside monitors. The

full screen, small text format in VIEW ALARMS is the only display format for the

full screen remote view monitors. The split screen central format is available only

for central monitors operating in split screen mode. (Refer to Figure 22-10).

• The analyzer is protected against the effects of a cardiac

defibrillation discharge, and it is safe to use on patients with a

cardiac pacemaker or other electrical stimulation.

CAUTION:

• The warm-up period is less than 2-minutes with full

accuracy after 30-minutes. You may use it prior to full

warm up but be aware of possible inaccuracies in gas

analysis.

WARNING:

• The used water trap and gas analyzer filter may contain

hazardous fluids and should be disposed of in accordance

with hospital procedures.

Setting Alarm Limits

You may set alarm limits for the following:

• Apnea (delay is measured in seconds) - high limit

• RR (respiratory rate) - high and low limits

•EtCO

2- high and low limits

•I CO

2- high limit

•FiO

2 - high and low limits

•FeO

2 - high and low limits

• Inspired and Expired N2O - high and low limits

• Inspired and Expired Agent - high and low limits

When alarm limits for EtCO2 and RR are initially enabled, the limit values depend

upon the patient’s current readings for those parameters (these limit values are

learned). Alarm limits for all other monitored parameters, when enabled, always

have the same fixed values.

Factory-set default values appear for alarm limits when you initially power up the

multigas unit. You may modify limits for any of the monitored parameters. These

modifications will remain in check until the unit is turned off or placed on Standby.

Default settings and ranges for alarm limits are shown in Table 2 on page 22-16.

Refer to Alarms on page 2-3 for additional information on alarms.

The VIEW ALARMS display format is the default for all full screen remote and

central monitors. In this format, all text is cleared from the waveform zone and ten

sets of parameter labels and their alarm limits are displayed. This is the only mode

that displays all alarm limits.

Selecting an Agent ID

You can manually choose an agent type by touching the SELECT AGENT key in

the main menu which opens the agent selection sub-menu. The prompt line above

the sub-menu identifies the detected agent: DES, SEV, ISO, HAL, ENF. MIX is

displayed if more than one agent is detected, and NONE if the agent type is not

identified.

Touching the AUTO ID key sets the analyzer to automatically use the agent type

detected. The five agent keys are the manual agent selection keys. Selecting one

of the agent keys forces the analyzer to use and report the concentration levels

based upon coefficient factors of the manually selected agent.

Agent ID Conflict Detection

In AUTO ID mode, if nonzero concentration levels are reported for more than

2-minutes and the agent type is not detected, a conflict is declared and the AUTO

ID key flashes.

In manual mode, when an agent type other than the selected agent type is

detected, a conflict is declared and the key with the detected agent type flashes.

When a conflict is declared, the agent parameter areas flash on all screens also.

The conflict is confirmed and the flashing of the keys and agent parameter areas

stops when either a selection is made in the Select Agent menu (a key is touched)

or the Select Agent menu is exited.

Conflict detection is restarted if:

• the agent concentration level goes to zero for more than 2-minutes.

• an agent type is selected that is not the type currently selected and not the

first agent type in conflict.

WARNING:

• In the event an agent is selected manually, but not

administered, the analyzer will detect the difference and

begin flashing the agent parameter label area and the

detected agent’s key. This is to alert the clinician to

possible errors.

CAUTION:

• If you see AGNT or MIX next to the numeric values on the

display, wait until HAL, ISO, ENF, SEV, or DES only appear

on the screen to indicate that the multigas analyzer

recognizes the agent you are using. The displayed values

are based on the coefficient factors of the last detected or

selected agent type. If the last detected or selected agent is

different than the agent you are using, you may receive

inaccurate values. Confirm the agent type before you

continue with patient treatment.

Selecting Stand By Mode

Stand By mode should be used for short durations only (for example, case

turnover). The Stand By feature keeps the unit warmed up.

The Stand By mode is not to be used in place of the power on/off. If the unit is in

Stand By mode and loses power (for example, if the unit is unplugged during

moving), when power is re-initiated, the analyzer may not display on the patient

monitor. It is best to use Stand By mode under supervision.

Press the front panel STAND BY button to initiate the Stand By mode. The pumps

stop drawing sampled gases, the analyzer display disappears from the monitor

screen, and the STAND BY light illuminates. Press STAND BY again to return the

analyzer to its normal operating mode when multigas monitoring is needed again.

Selecting a Pump Speed

You may select any of the following volumes of sampled gases that are drawn for

use in measuring gas values: 50, 75, 100, 125, 150, 175, or 200 ml/min, or you

may suspend sampling (pumps off). The unit defaults to 175 ml/min whenever it is

turned on.

Initiating a Calibration

Daily O2 Sensor Test

The oxygen channel may drift slightly over time; therefore, an O2 sensor test

should be performed daily. This test uses room air to check for aging of the

oxygen sensor and may be performed at any time (except during the first

4-minutes of operation). This check does not require special equipment or

additional gases.

If drift or aging of the sensor is detected, the 100% O2 SPAN REQUIRED

message will be displayed and a 100% O2 span must then be performed to

calibrate the O2 sensor for high concentration levels (>60%) of oxygen.

Further action is needed if an O2 SPAN FAILURE message or an O2 SPAN

REQUIRED message displays on the screen. However, the gas analyzer is still

functioning and all Agent, CO2, and N2O values remain accurate. The unit can be

used until the required calibrations can be performed. To remove the message

from the screen, simply touch the GAS key and then the NORMAL SCREEN key

of the monitor.

CAUTION:

• If the unit is taken out of Stand By and the analyzer display

does not appear on the patient monitor, turn the unit off

and then power on correctly.

WARNING:

• The gas analyzer calibrations must be performed by

qualified personnel.

100% O2 Span Calibration

The 100% O2 Span is used to calibrate the response of the oxygen sensor to

100% O2. This function sets the level for oxygen so the monitor displays 100%

when pure oxygen is input to the unit.

The 100% O2 Span calibration should be performed monthly or whenever the

FiO2 value is not between 98% and 100% when sampling pure (100%) oxygen.

The 100% O2 calibration must be done correctly. A source of pure O2 with

adequate flow is required to perform this calibration. Some institutions rely on their

biomedical engineering department to perform this calibration. When the 100% O2

calibration is completed successfully, the monitor displays a normal screen with

measured values of all gases.

Further action is needed if an O2 SPAN FAILURE message or an O2 CELL

REPLACEMENT REQUIRED message displays on the screen. However, the gas

analyzer is still functioning and all Agent, CO2, and N2O values remain accurate.

The unit can continue to be used until the required action can be performed. To

remove the message from the screen, simply touch the GAS key and then the

NORMAL SCREEN key of the monitor.

O2 Cell Replacement

To change an O2 cell, plan on the analyzer to be out of operation for

approximately 2-hours. Therefore, if the day begins with a CHECK O2 SENSOR

calibration and it is found that additional calibration or O2 sensor replacement is

required, you can simply schedule that within your department (when the

biomedical engineers are available). You may continue to use the analyzer until

there is time to re-calibrate the unit or change the sensor.

Autozero Calibration

To guarantee accurate readings, the zero reference of the multigas analyzer is

automatically calibrated on a regular basis. Autozero calibrations last less than

1.5-seconds and are performed without notice to the user.

The interval between autozero calibrations depends upon the amount of time the

unit operates (either in normal or stand by mode). After the unit has been ON for

at least 30-minutes, and has become thermally stable, autozero occurs in normal

mode at approximately 10-minute intervals.

CAUTION:

• If the message ??? appears in the numerics of FiO2and

FeO2 at any time you are monitoring a patient, you must

perform a check O2 sensor test.

CAUTION:

• Performing a 100% O2 span calibration without using the

proper concentration and flow of oxygen will result in span

calibration failure.

To span calibrate O2 sensor with

100% O2:

1Allow unit to stabilize for

30-minutes.

2Touch GAS.

3Touch CAL.

4Disconnect the sample line

from patient.

5Connect the sample line to the

sampling port of an airway

T-adapter.

6Connect the airway T-adapter

to a source of 100% oxygen

supply.

7Adjust the oxygen supply to

flow through the T-adapter at a

rate of approximately 500

ml/min.

8Wait for O2 value to stabilize.

9Touch 100% O2 SPAN.

10 Select YES.

11 At completion of successful

test, normal monitoring will

Pump Calibration

This function is used by service personnel to adjust the pump flow rate. Refer to

the 90518 Multigas Analyzer Service Manual P/N 070-0643-xx for details.

Gas Span Calibration

A gas span calibration is recommended whenever gas values appear to be too

low or too high. Always perform a leak test first to verify that the suspected values

are not the result of a leak (poor connection, cracked water trap, etc.).

The gas calibration (SPAN) procedure is used to recalibrate the gas channels for

CO2, N2O, and anesthetic agents. This procedure should be done every

30-90 days. Equipment required for this calibration includes a gas mixture for the

calibration, calibration adapter kit, gas pressure regulator, and flow meter. This

equipment can be purchased from Spacelabs Medical Supplies Products.

Refer to the 90518 Multigas Analyzer Service Manual (P/N 070-0643-xx) for

details on calibrating the analyzer.

WARNING:

• Performing a gas span calibration without the calibrated

gas mixture connected adversely affects the accuracy of

the analyzer.

• Gas span calibrations must be performed by trained

personnel only.

• The waveform display and the numeric values may disappear

during calibration.

Suspending Sampling

Sampling may be suspended by touching the SUSPEND SAMPLING key under

the following conditions:

• When suctioning a patient

• Use (by the patient) is temporarily discontinued

• Nebulized drugs are being used

This stops the sampling pump and keeps the system free of debris. Touch the

RESUME SAMPLING key to resume sampling.

When sampling is suspended, the CAL key is disabled.

Refer to Patient Connection on page 22-8 for examples of recommended suction

system setups.

CAUTION:

• The sampling must be resumed for proper monitoring of

respiratory gases.

To suspend sampling:

1Touch GAS.

2Touch SUSPEND SAMPLING.

3Touch RESUME SAMPLING

when finished.

BIS

Overview

The Spacelabs Medical 90482 Bispectral Index® (BIS®) Analysis module acquires

and processes real-time EEG data into a BIS number between 0 and 100. The

EEG data is also displayed as:

•BIS

• Spectral Edge Frequency (SEF)

• Median Power (MF)

• EMGL (EMG energy in the 70–110 Hz band)

• Signal Quality Index (SQI)

• Suppression Ratio (SR)

The BIS module may be used in any of the Spacelabs Medical monitors listed in

Table 1, with or without other Spacelabs Medical modules.

The BIS module uses disposable BIS sensors from Aspect Medical, Inc., a Digital

Signal Converter (DSC), and a patient interface cable.

CAUTION:

• Place the sensors as far away from the electrosurgery site

as possible because considerable high frequency current

may flow into the electrodes. This can cause patient burns,

especially if a defect is present in the neutral cable of the

electrosurgical unit. Placing electrodes too close to the

electrosurgery site can also cause a noisy EEG trace.

• Do not allow conductive parts of sensors or connectors,

including the neutral electrode, to contact other conductive

parts, including the ground.

• Detach all connectors and cables by grasping the

connectors and pulling them straight out. Do not detach

connectors and cables by pulling on the cables

themselves.

Digital Signal Converter

The digital signal converter (DSC) receives the EEG input from the patient and

converts it to digital information that is processed by the module.

Figure 23-2: Digital signal converter

The DSC plugs into the front of the module as shown in Figure 23-1.

Patient Interface Cable

The patient interface cable (PIC) is attached to the three-foot cable on the DSC

and connects to the BIS sensor as shown in Figure 23-1.

To attach the PIC to the BIS sensor:

1. Remove the BIS sensor from its packaging.

2. Locate the small, raised arrows on both the light-blue end of the PIC connector

and the BIS sensor connector.

Plug the BIS sensor into the PIC so that the arrows are on the same side and

point toward each other. You may attach the BIS sensor to the PIC cable either

before or after the sensor is placed on the patient.

•The PIC is not a disposable cable. Do not dispose of it when

you dispose of the attached BIS Sensor.

• A cable tie is provided with the PIC to secure it to the DSC

cable to prevent accidental disposal of the PIC.

To replace a faulty or damaged PIC:

1. Remove and discard the unusable cable.

2. Locate the end with a yellow dot on the PIC connector.

3. Engage the PIC connector and the DSC cable connector with the yellow dots

oriented the same way, ensuring that they are fully seated.

Patient Preparation

To prepare the patient for monitoring:

1. Make sure the skin surface is clean and dry.

2. Position BIS sensor circle #1 and BIS sensor circle #2 high on the center of

the patient’s forehead approximately 1.5 inches above the bridge of the nose.

3. Apply BIS sensor circle #3 on either temple between the corner of the patient’s

eye and the hairline.

4. Insert the tab into the patient interface cable until it is fully engaged (if you

prefer, you may do this step before applying the sensor to the patient).

5. Using your finger, trace around the adhesive areas of the sensor, including the

space between circles #1 and #2 to assure good adhesion and to prevent any

bridging between the sensor elements.

6. Press each circle firmly and hold for 5-seconds to assure adequate prepping

and to maximize sensor performance.

Initialization

Before processing data, the BIS sensor must be applied to the patient.

When the sensor is applied and the PIC and DSC are connected to the module,

you are ready to begin BIS monitoring.

1. Touch BIS.

2. Touch START PROCED

(refer to START/STOP PROCED Key on page 23-16).

3. Touch YES at the Clear Data? prompt, and the module will automatically

perform an impedance test.

CAUTION:

• The BIS sensor will only work if it is placed on the patient’s

forehead. Accordingly, it should not be used with any

surgical procedure that precludes such placement.

CAUTION:

• Do not expose the BIS sensor to surgical skin preparation

solutions. This may result in harm to the patient’s skin.

Impedance Values

If the impedance value is too high, it could indicate that the BIS sensor is no

longer making good contact and needs to be examined. Usually artifacts will

signal this fact.

After touching the TEST ELECT key, additional feedback is given to the user by

flashing the impedance value when the value exceeds the threshold. (Refer to

Impedance Montage on page 23-11 and TEST ELECT Key on page 23-15.)

The Pass/Fail thresholds for the terminals are:

• Ground < 100 Kohms

• Center < 7.5 Kohms

• Left/Right < 7.5 Kohms

Normal Bedside Display Format

Monitor Software

The full bedside view requires three waveform zones. The example in Figure 23-5

displays the BIS plot and EMGL trends.

Figure 23-5: BIS bedside display (3 zones)

Analog Waveform

A single waveform is displayed in a box that is 300 pixels wide by 60 pixels high.

With this display, roughly 8-seconds of waveform data can be displayed at a

sweep speed of 15 mm/sec, 4-seconds at 30 mm/sec, and 2.4-seconds at

50 mm/sec.

• In normal use, the typical impedance value for the ground is

less than or equal to 6 Kohms, while the values for the center

and left/right terminals are between 0.5 and 1.5 Kohms.

• The user cannot control the impedance thresholds.

Alarm Display

When the alarms are turned ON, the high and low alarm limit values are

displayed. When the alarms are turned OFF, BIS ALM OFF is displayed. When

the alarms are temporarily suspended, BIS ALM SUSP is displayed.

The alarm display consists of a block of reverse video text containing either BIS

ALM OFF or BIS ALM SUSP. They are mutually exclusive, and only one will be

displayed in the numeric area.

• Turn the alarms OFF by touching ALARM OFF on the Alarm Limits menu.

• Temporarily suspend the alarms by pressing the ALARM SUSPEND button

on the monitor.

Alarm Suspend

Press the ALARM SUSPEND button on the monitor to temporarily turn off the

audible alarm for 3-minutes. The text BIS ALM SUSP replaces the alarm limits.

The BIS number continues to flash if the limit is exceeded.

When the temporary time has elapsed, the display returns to normal behavior. If

the audible alarm is enabled, the alarm tone will sound again, and the limit

number will flash.

In the split screen display, the bell symbol displays in reverse video when the

alarms are enabled but suspended. During an alarm violation, the bell symbol

flashes in reverse video.

Impedance Montage

If, during BIS monitoring, you wish to test impedance without losing your trended

data, you can perform an impedance test. An impedance test is automatically

checked (or tested) every 10-minutes.

The impedance montage is a temporary display that appears when the BIS

sensor is connected to a patient and you touch the TEST ELECT key (refer to

TEST ELECT Key on page 23-15).

The montage displays on the right side of the screen to the right of the second

wave zone area from the top.

Remote View Display Format

The “Remote View” software option on Ultraview monitors allows you to view the

BIS parameter from a remote monitor. This display shows the BIS plot in a single

display zone format. No analog waveforms are available in this mode.

Figure 23-10: Remote display

Remote monitors permit one display zone to be used to display remote channels

from other monitors, regardless of the type and the number of zones that are in

use at the bedside monitor. When viewing the BIS from another monitor, the lower

part of the BIS trend will not be visible due to the patient’s name being there.

• All processing is suspended until you stop the impedance test

by touching EXIT ELECT.

Definitions

BIS — Bispectral Index Analysis. A mathematical calculation derived from the

frequency, power, and phase throughout the entire frequency range of the EEG.

The Index is a number between 0 and 100.

DSC — The Digital Signal Converter. The DSC contains the input connector,

amplifiers, and digitizer for the 90482 one channel EEG. The DSC is configured

for referential montage monitoring.

EEG — Electroencephalogram. Real-time electrical activity of the brain. The EEG

waveform can be further separated (digitized) into elements. The signal can be

processed in time, frequency, and Fourier analysis.

EMG — Electromyogram. Electrical activity of the muscles. Processed as the

absolute power in the frequency (Hz) range. This product calculates EMGL, which

is over a fixed 70 to 110 Hz frequency range.

EMGL — EMG Low. Refer to EMG.

Epoch — The time during which the bispectral index is calculated.

MF — Median Power Frequency measured in Hz. The frequency at which 50% of

the total power lies equally on either side. The frequency range is between 0.5

and 30 Hz.

Montage — A pattern of linking electrodes together over the scalp to generate a

display of EEG channels in a particular way. Montages can be bipolar or

referential.

PIC — The Patient Interface Cable. Used by the BIS module. This cable is

configured to tell the DSC and module to automatically use a single channel

montage for the BIS Sensor. The BIS Sensor is normally placed on the left or right

side of the forehead.

SEF — Spectral Edge Frequency. The frequency (measured in Hz) at which 95%

of the total EEG power lies below it and 5% lies above it. Frequency range is

between 0.5 and 30 Hz.

SQI — Signal Quality Index. The percentage of good epochs in the last

60-seconds that are used to calculate the Bispectal Index and spectral variables.

Not affected by the suppression ratio. Percentage values range between 1 and

100.

SR — Suppression Ratio. The percentage of time in the last 60-seconds in which

the EEG signal is considered suppressed. Percentage values range from 0.0 to

100.

Calculations

Overview

The Clinical Calculations feature can be divided into two types: (1) Physiologic

and (2) Drug Dosage. Physiologic calculations include hemodynamic, respiration,

oxygenation, and renal. These calculations use input values entered manually or

collected automatically by the system to produce a set of output values. Drug

Dosage calculations enable you to determine infusion rates for drugs based on

drug concentration, desired dose, patient weight, and type (adult or neonate).

Setting Up Physiologic Calculations

Values are entered into the system in several ways. You can take a snapshot of

currently monitored inputs by selecting the NEW ENTRY key (refer to Creating a

New Entry on page 25-8). You may also specify a day and time to gather input

data from the past, although this function is generally limited to the past 24-hours.

The system displays a combined total of 200 entries into the four physiologic

calculations tables. Each table has an Edit Inputs menu that is used to edit input

data. You can also create a record of both input and output data by printing the

displayed table.

Ultraview Care Network

25-6

Setting Up Drug Dosage Calculations

The Drug Dosage calculation feature enables you to edit the inputs and to store

up to six drug records. Titration tables are displayed for each drug record entered.

Drug dosage calculations operate similarly to physiologic calculations except that

weight is handled differently, and that you must select an ADULT or NEONATE

patient type. Refer to Entering Patient Type and Gender on page 3-9 for details on

adult/neonate selection.

Accessing Calculation Data

Calculations can be accessed via the local bedside monitor or from a remote

monitor on the network depending upon the options purchased. Contact your

system administrator for details if you are unable to access this function.

The data displayed in the Calculations table is from the local bedside or the

specified remote monitor as selected.

Updating Data Between Monitors

The UPDATE DATA key is used to synchronize calculation data between multiple

monitors. For example, if lab data for calculations were entered at the central

monitor and stored in the bedside monitor database, using the UPDATE DATA

key would provide those values for calculations performed at the bedside.

Display Detail - Physiologic Calculations

Tables for Physiologic calculations occupy several display zones above the

message line, allowing display of waveforms on the remaining display zones of

the screen. The Drug Dosage calculations table has a different format, but

occupies the same four lower display zones.

WARNING:

• If the monitor is turned OFF, all clinical calculations data

will be lost.

column.

The new record’s DAY/TIME key is highlighted and contains the current day and

time. The available input values are displayed in the input column and calculated

results appear in the output column. Any unavailable inputs or outputs are

displayed as question marks.

NEW ENTRY does not function when a total of 200 records exist in all the

Physiologic calculations tables for the selected system. If you want to make

further entries, you must first delete some of the existing entries from one or more

of the calculations tables.

Editing Inputs

Each type of calculation displays its own Edit Inputs menu containing the inputs

listed in the upper part of the Calcs table. The name of the input and units of

measure appear on each EDIT INPUTS key for the Physiologic calculations. Once

an input has been edited, the letter e is displayed immediately after the edited

value in the table.

When you select an input key, the on-screen keypad appears. Refer to Using the

On-Screen Keypad (Ultraview 1030/1050/1500/1600 only) on page 3-7 for on-

system performance.

Cardiac output values from a Cardiac Output (CO) module automatically create

records in the Hemodynamic Calculation table.

When you create a new entry, any current values for HR, MAP, CVP, MPA, and

PCWP are displayed in the table. The system will enter the current body surface

value into the table, if available. The most recent CO value (if less than

15-minutes old) is also put into the table. If the system locates a CO value, then

values for MAP, CVP, MPA, or PCWP not currently available are put into the table

from the CO record. Any inputs which remain unavailable display question marks.

Calculations

Hemodynamic Calculations require several specific pressure values, including

CVP, MAP, and PCWP. CVP and MAP are monitored continuously; PCWP is an

episodic value. A data substitution may occur if any of these pressure values are

not available when you touch NEW ENTRY. When a substitution occurs, one of

the error messages listed here displays on the message line.

•Warning...RAP has been substituted for CVP.

A continuous RAP value is used instead of the continuous CVP value if CVP

is not available.

•Warning...NIBP has been substituted for MAP.

An episodic mean NIBP value which is less than 15-minutes old is used

instead of MAP if the continuous MAP value is not available.

•Warning...LAP has been substituted for PCWP.

A continuous LAP value is used instead of the episodic PCWP value if the

PCWP value is not available or is more than 15-minutes old.

Changing Units of Measure

Units of measurement are displayed on the table to the right of the data values.

Changing the selected units for AMOUNT may also change the displayed units for

CONC. Changing the selected units for DOSE may also change the displayed

units for DOSE/WT and TOTAL DOSE.

If the values for CONC, DOSE/HR, DOSE/WT/HR, and TOTAL DOSE exceed the

range of their currently selected units, that value is divided by 1000 and the units

change accordingly. For example, if the value for TOTAL DOSE is 123,456 mg, it

will be displayed as 123.46 g. This value is rounded because only two digits can

be displayed to the right of the decimal point.

WEIGHT is displayed in kilograms (kg), regardless of the system’s setting for

weight. Weights in pounds automatically convert to kilograms prior to being

displayed.

Units Submenu

This menu allows you to choose one of three types of units (grams, mEq, and

units) for AMOUNT or DOSE.

Changing the units for AMOUNT may change the units for CONC. Changing the

unit type for AMOUNT changes the unit type for DOSE. Either may scale the

values and units for CONC, DOSE, DOSE/WT, and TOTAL DOSE up or down for

values less than 0.01 or greater than 9999.99.

Changing the units for DOSE may change the units for DOSE/WT and TOTAL

DOSE. As a result, both the minute and hour values for DOSE and DOSE/WT

may change.

Dose Submenu

When you select DOSE in the Edit Inputs menu, four dose type keys are

displayed. Select any of these keys to edit the corresponding value shown in the

Drug Dosage Calculations table. The system automatically calculates and

displays the changes for the other three dose types in the Drug Dosage

Calculations table.

The dose type selected for a specific drug defines the dose unit used for that

drug’s titration tables. When you store a Drug Calculation record, the dose type is

also stored.

Storing a Record

Touch STORE ENTRY to store the record and to display the letter s under the

associated DRUG key. You can store six records, one for each DRUG key. If you

edit a record that has been stored, the system removes the letter s because the

newly edited changes have not been stored.

Displaying Titration Tables

The VARY RATE/DOSE toggle key and DOSE TYPE keys are displayed when

you touch TITRATION TABLE. VARY RATE varies the rate (holding the

concentration constant) and calculates (titrates) the corresponding dose using the

selected dose unit type. VARY DOSE varies the dose (holding the drug

concentration constant) and calculates (titrates) the corresponding delivery rate in

ml/hr.

The DOSE TYPE key displays the DOSE TYPE menu where the dose values are

displayed and the Titration table is updated with the selected dose type. This key

is disabled whenever VARY RATE is selected, and enabled when VARY DOSE is

selected.

In the titration tables, flow rate and dose are calculated using the equations below.

Figure 25-4: Titration table

Figure 25-4 displays a sample Vary Rate Titration table. The amount and volume

is displayed at the top of the table along with the dose and rate units. The units for

amount and dose are the same units used in the Drug Dosage table.

The drug (A through F) and patient weight are displayed at the top of the table.

Dosages can vary between 0.01 and 9999.99 mg/min, and rates can vary

between 0.1 and 999.99 ml/hr.

The patient type (ADULT or NEONATE) is displayed in the upper left corner of the

table.

Recalculations

You can recalculate all Drug Dosage inputs except for the amount/hour entries

shown for DOSE and DOSE/WT. In most cases, changing one parameter

automatically recalculates and redisplays other parameters under that DRUG key.

Table 16 shows adult patient recalculation rules, except where noted in AMOUNT

and VOLUME. When TITRATE on the MIX/TITRATE key is selected, DOSE,

DOSE/WEIGHT, and FLOW RATE results are the same for Adult and Neonatal.

consistent by transferring master drugs lists from one bed to another allowing

remote bed access to the master drug list.

• The drug default values for drugs A through F can be overwritten

and not affect the master drug list entry. However, selecting

another drug name for drug A, B, C, D, E, or F will override all

previously-edited values and will insert the master default

settings. Ensure that the changes are effected after selecting the

drug name (and not before).

Trends

Overview

Trends are a convenient way of displaying numeric data that has been collected

for a patient over the last 24-hours. Your monitor can display a graphic trend or

tabular trend (depending on the option purchased) of collected numeric data for

every parameter except delta temperature and EEG. This data appears in a table

format similar to common flowsheets or spreadsheets.

Graphic trends can appear in three formats.

• Continuous trends represent parameters with continuous monitoring. A solid

line connects trend points.

• Episodic trends represent parameters that produce individual events.

Episodic values are displayed as an x,+, or 0. A dotted line connects each

episode.

• Histogram trends are displayed as vertical bars starting at a base of zero.

The system collects trend values every minute and episodic trend values as they

become available. Up to the last 24-hours of collected data in memory is

displayed and the system saves trend values for as long as memory limitations

allow. In most cases, an episodic trend contains at least 30 values.

• When you suspend alarms with the TONE RESET/ALM

SUSPEND key the system may not collect trend data. Contact

your system administrator to enable this function.

To display a trend:

1Touch SPECIAL FUNCTIONS.

2a Select LOCAL TRENDS/

CALCS or REMOTE TRENDS/

2b If you touched REMOTE

TRENDS/CALCS, select a bed.

3a Touch GRAPHIC TRENDS.

Graphic Trends Features

Selecting Trend Parameters

The first time you display a patient’s graphic trend, the highest priority parameter

is displayed on the bottom trend graph and the next highest priority parameter is

displayed on the top graph. You can view other trends by selecting them from the

Trend Parameter menu.

Using the Cursor

The graphic trends cursor is a solid, vertical line that moves across the entire

trend graph (refer to Figure 26-1 on page 26-4). The home position of the cursor is

at the extreme right end of the graph. Once the cursor moves from its home

position, the CURRENT VALUES label changes to reflect the cursor’s current

position. The CURRENT VALUES label now displays VALUES at and the time.

These values represent the data acquired from the patient.

Selecting a Time Base

The time base for each trend graph can be set for 2-, 6-, 12-, or 24-hours. The

displayed resolution for each time base is:

Selecting a Scale Size

You can adjust the scale for each parameter. Initially, the system selects a scale

that includes all monitored values for the displayed parameter. You may adjust the

scales using the arrow keys.

• The trend graph continues to update EXCEPT when the cursor

is moved from its home position. It updates again when the

cursor returns to its home position.

• When switching between Graphic Trends and Tabular Trends,

the cursor remains in the same position. For example, if the

cursor is placed on data 2-hours previous to the current time in

Graphic Trends, when moving directly to Tabular Trends, the

screen will display the same time frame, and the corresponding

data column will be highlighted.

2-hours = 1-minute

6-hours = 1-minute

12-hours = 2-minutes

24-hours = 4-minutes

To select a parameter for the top

or bottom graph:

1Select TOP GRAPH or

BOTTOM GRAPH.

2Select desired parameter.

To move the cursor:

1Touch cursor keys as needed.

To set a trend graph time base:

1Touch TIME BASE.

2Select 2, 6, 12, or 24 HRS.

To adjust the scale size:

1Touch SIZE.

2Select desired parameter key.

3Use arrow keys to adjust.

Trends

26-7

Expanding the Trend Display

You may expand the trend display to include only an hour’s worth of information.

With EXPAND ON, the TIME BASE key does not operate and updating of the

trend graph is suspended on the graph as it is currently displayed. When

EXPAND is OFF, the trend graph returns to its original display. Moving the cursor

while EXPAND is ON does not change the cursor’s position in the OFF mode.

Tabular Trends Features

Setting a Time Interval

You can display acquired data at various time intervals: 1-, 5-, 10-, 15-, and

30-minutes; and 1-, 1.5-, and 3-hours.

For continuous data, the value displayed in the tabular trend table is the value

taken at the displayed time. It is not an average of all readings taken during that

time period.

When more than one episodic reading occurs in the same time interval, only the

most recent value is displayed. Asterisks to the right of the episodic value

indicates that more data entries are available for that time interval.

The trend table automatically updates at the end of each time interval. This shifts

all data columns to the left to include the new interval.

Viewing Off-Screen Information

You can view up to 22 rows and 7 columns of parameter data on a single screen

in a tabular trend.

You can view additional parameters by moving rows up or down. When you select

PAGE, the arrow keys move the entire page up or down. When you select

SCROLL, the arrow keys move the display up or down one parameter row at a

time.

You can view data collected at other times by moving columns left or right. When

you select PAGE, the arrow keys move the display to show an entirely new set of

columns. When you select SCROLL, the arrow keys move the display left or right

by one column.

• Updating is suspended when you review data while paging or

scrolling.

To expand the trend display:

1Touch either CURSOR key to

move the cursor to the desired

location.

2Select EXPAND ON.

To set a time interval

1Touch TIME INTERVAL.

2Select the desired time interval.

To view additional parameters

and data (for Tabular Trends):

1Select PAGE or SCROLL.

2Use the ↑ and ↓ arrow keys to

move parameter rows up or

down.

To view additional parameters

and data (from a different time):

1Use the PAGE and SCROLL up

and down arrow keys to move

parameter rows vertically.

Programming Access Codes

Access codes ensure that the receiver responds only to a remote keypad with a

matching code number. If a keypad’s access code differs from the receiver’s, the

command is ignored. This prevents interference from other remote keypads.

The programmed access code (1 to 32) is displayed on the monitor. This code is

stored in the monitor’s memory and retained whenever the monitor is reset or

powered OFF.

When programming a monitor's access code, the keypad's access code must

initially match the receiver's. The new access code is programmed simultaneously

with the keypad's. The monitor temporarily displays the remote keypad's access

code, then returns to displaying its own code.

• Remote keypad systems can be operated in an unsecured

mode without access codes so that the receiver accepts

commands from any remote keypad. When in the unsecured

mode, the word ALL appears on the monitor.

• To prevent inadvertently changing other access codes, unplug

all other monitors (or move the remote keypad directly in front of

the monitor to be programmed) and place your finger over the

remote keypad's infrared window during programming

(sufficient signal transmits through your finger to program the

receiver).

Remote Display

Overview

The Ultraview 1700 provides an optional output to a remote-configurable

secondary display. This secondary display enables you to view selected

parameters from the primary display.

The primary monitor is used to control the configuration and waveform display

characteristics of the secondary remote display. The secondary display has no

touchscreen surface or functional keys.

Setting Up the Secondary Display

The Configuration menu for the secondary display appears on the primary

monitor. The menu functions identically to the primary monitor’s menu although it

has three additional keys.

Selecting Colors and Priorities

Each parameter has a specific default color and priority. You can change the

colors or priority levels of the parameters to customize the monitor to your specific

needs.

After making any configuration change, touch STORE to make the secondary

display changes permanent. If you do not touch STORE, the system disregards

your changes.

The PARAMETER CONFIG key allows you to change the system default priorities

and colors. The current parameter priority and color default is visible from the

DISPLAY PRIORITIES toggle key. The LOCAL key displays the current active

• Your display may not be configured to allow changes to

parameter priorities or colors. Contact your hospital system

administrator for details.

To set up the remote display:

1Touch MONITOR SETUP.

2Touch SECONDARY CONFIG.

3Touch PARAMETER CONFIG.

4Select a parameter.

5Select the destination priority.

6Select a color.

7Select the parameter key to be

colored (the key and waveform

will appear in the chosen color).

8Touch STORE to store local

color and priority settings.

Ultraview Care Network

28-2

parameters and the ALL key displays all possible parameters. Each parameter is

assigned a display priority, with the highest priority appearing at the top of the

screen.

Blank parameter keys allow you to force a space above, between, or below other

parameters. Blanks can be inserted into any priority template by selecting the

blank and putting it into the desired location. This causes a blank zone to be

inserted into the corresponding display area and all active parameters with a

lower priority to be pushed down.

The STORE key stores the current local priority and color settings into non-volatile

memory.

The RESTORE key restores the last stored local priorities and color settings from

memory.

The FACTORY DEFAULTS key restores the factory default priority and color

settings.

Copying Stored Values of the Primary

Monitor

Touch COPY PRIMARY PRIO/COLOR to duplicate the primary display’s stored

settings for priorities and colors on the secondary display. Touch STORE to put

these changes into effect.

You can use the Copy Primary Prio/Color function to remove blank zones

resulting from parameters that were deleted while the secondary display was in

Lock mode.

Restoring a Stored Value

Touch RESTORE to reset the secondary display’s configuration screen to its last

stored changes. Restoring the screen also stops the Copy Primary function (if

STORE has not yet been touched).

Copying Primary Attributes to the

Secondary

Touch COPY PRIMARY PARAM ATTR to copy the primary's current parameter

attributes or settings to the secondary display. Parameter colors and priorities are

not copied.

Use this key to:

• Remove any blank zones caused by deleting a parameter while the

secondary was locked.

• Insert any new parameters added while the secondary was locked.

• Change sizes, sweep speeds, full scales ON/OFF, etc., to match the primary

monitor’s configuration.

Resetting Default Values

Touching FACTORY DEFAULTS resets the secondary display to its factory

values. Touch STORE to make these changes permanent.

Options that can be reset include:

• Relative priorities and colors to factory default configuration of primary

• Blanks caused by deleting a parameter while in Lock Mode

Touching this key does not insert any new parameters added while the secondary

display was in Lock Mode.

Tracking or Locking Displays

In addition to parameter color and priority, you may configure other attributes of

the secondary display to be different from the primary monitor. To make additional

adjustments to each display separately, select LOCK after you configure the

secondary display. This allows the secondary display to remain largely

unchanged when you adjust the primary display. If you need the secondary

display to duplicate changes to the primary, set the secondary display to TRACK.

Refer to the Table 1 (where X = yes) for the effect of Track and Lock on each

display characteristic.

To make additional changes to the secondary screen after you select LOCK,

return to the Secondary Configuration menu and touch TRACK.

Patient Data Logger

Overview

The Patient Data Logger option automatically sends patient vital signs from the

monitor to an external device, such as a printer or a terminal. Episodic patient

data is also sampled and transmitted. The output is in the form of ASCII text byte

strings, and is printed using standard RS232 serial communications via the

monitor’s serial port. Refer to the Display Detail on page 29-5 for further

information.

This option continues to send data whether the external device is on-line or off-

line. Data transmission can be stopped by reassigning the data port or disabling

the Patient Data Logger.

Your system administrator (or other designated personnel) must first set up

communication between the monitor and the external device by assigning the

serial port to Patient Data Logger, and then adjusting the serial port settings. The

various serial settings can be adjusted to suit the device attached to the serial

port. Refer to the appropriate service manual for more details.

The sample rate refers to the frequency of data sampling and can be set to time

intervals ranging from 5-seconds to 60-minutes. The new sample rate takes effect

at once.

The data logger output requires a serial cable that swaps pins (refer to Table 1).

The serial cable must be properly connected at both ends and the data logger

output enabled.

• The option is only available on bedside monitors.

• Ensure that any cables or other computer or communications

equipment connected to the bedside monitor comply with

applicable medical standards.

• The combination of PDL baud rate and sample rate must be

selected carefully. Slow baud rates, in combination with

frequent data transmissions, may cause loss of data. This is

especially true if a large amount of patient vital sign data is

being monitored. However, some devices cannot accept data at

high baud rates. This may limit the range of sample rates at

which your device can accept data readings from the monitors.

• All lines on this report are terminated by a line-feed, carriage-

return combination.

• Lines may wrap if the line length exceeds the display or printer

width.

• The report prints a maximum of 132 characters per line and

2 lines per entry.

• The report prints data from a maximum of 11 parameter groups

(for example, ECG, RESP, ART, etc.). (Fewer parameters are

printed if the line length limit is reached.)

Ultraview Care Network

Data Printouts

Each line of the data printout may contain up to 132 characters and is terminated

with line feed and carriage return characters.

The PDL transmits two types of information: page headers and data lines. The

page header appears at the top of each page and contains the patient’s name, the

bed number, and the current date. A new page is generated when any the

following situations occur:

• The end of a page is reached (that is, 50 data lines have been transmitted).

• The monitored vital signs parameters change.

• The patient name or bed number changes.

• The current date changes.

Data lines are transmitted at the interval specified at configuration. Each data line

contains the time that the data was collected, as well as the data collected for

each vital sign parameter being monitored.

• If you are monitoring a large number of parameters and have an

80-column printer, the data from one reading may require more

than one line. If your printer has a wrap-around feature, this will

be handled automatically. If you prefer that each data reading fit

onto one line, condense the printer’s type or use a wide-

carriage (132 column) printer.

Ultraview Care Network Product

Specifications

System Safety Specifications

System Introduction and Network Basics on page 1-1 includes information

concerning the interconnection of equipment within the Ultraview Care Network.

Initial connection of auxiliary line-operated equipment to a monitor must be

performed by a hospital biomedical engineer or a Spacelabs Medical Customer

Service Representative. For further information or instructions regarding

interconnection of units, contact a qualified service person or your local Spacelabs

Medical representative.

After installation and/or interconnection with other units, the equipment leakage

current shall not exceed the local (provincial) acceptable values.

Accessory equipment connected to the analog and digital interfaces must be

certified according to the respective IEC standards (that is, IEC 950 for data

processing equipment and IEC 601-1 for medical equipment). All configurations

shall comply with the system standard IEC 601-1-1+A1. Everyone who connects

additional equipment to the signal input part or signal output part configures a

medical system, and is, therefore, responsible to ensure that the system complies

with the requirements of the system standard IEC 601-1-1+A1. If in doubt, consult

the technical service department or your local customer service representative.

All Spacelabs Medical equipment is intended for use with a fixed mains socket-

outlet. If a system is configured using multiple portable socket-outlets, this system

must be reviewed for compliance with IEC 601-1-1+A1, including the maximum

load and enclosure leakage currents requirements. The multiple portable socket

outlet cannot be placed on the floor. If the leakage limit is exceeded, a second

Protective Earth, fixed at both ends with a tool, may be necessary. This second

Protective Earth must be tested to the requirements of clause 18 of IEC 601-1.

Equipment weighing more than 20 kg is not portable. To lift heavy equipment,

support under corners and lift according to hospital procedures.

Use of patient cables, transducers, sensors and supplies other than those

specified by Spacelabs Medical may degrade equipment performance, including

defibrillation protection.

Ultraview Care Network

31-2

Input leakage current for all patient input channels is less than 10 µA making ECG

units suitable for direct cardiac application. The maximum non-destructive voltage

that can be applied to any input or output connector on the monitors, modules or

printers is +5 V. All signal inputs or outputs are for exclusive connection to

equipment specified by Spacelabs Medical.

Disposal of these devices and all accessories must be in accordance with local

and federal laws.

When interconnecting equipment, avoid using optional battery operation. If such

operation cannot be avoided, the battery-operated instrument must be grounded

using the ground terminal on the rear panel or the protective ground (earth) in the

power cord.

Power Cord:

• 3-wire, 18-gauge, hospital grade, or

• 3-wire, 0.75mm2, European harmonized.

Plug:

• 3-terminal polarized, with protective ground.
