vi
Precautions
General
Federal law in the USA or Canada restricts this device to sale by, or on, the order of a physician.
The accuracy of the measurements can be affected by the position of the patient, the patient’s
physiological condition, and other factors. Always consult a physician for interpretation of
measurements made by this monitor.
To avoid monitor fall, secure monitor on the shelf or bracket prior to use.
An explosion hazard exists if this monitor is used in the presence of flammable anesthetics.
The operator should read and thoroughly understand this manual completely before attempting to
operate the 3160 MRI Physiological Monitoring System.
If any system failure occurs (e.g. an unexplained continuous audible alarm) remove the monitor
from use, and refer it to qualified service personnel.
When an “X” appears in the Alarm Bell symbol, the audible alarm tone will not sound for any
reason.
Perform operational checkout before each use. If monitor fails to function properly, refer to
qualified service personnel.
For safe and accurate operation, use only recommended Invivo patient cable, lead wires, cuffs,
hoses, sensors, tubing, etc. A listing of these can be found in the Accessory Listing within this
manual, or by contacting Invivo directly.
For continued operation, always connect the monitor to AC Main Power when a Low Battery
indication occurs. Failure to do this can lead to interruption of monitoring and/or damage to the
monitor’s battery(s).
The system may not conform to all performance specifications if stored or used outside the
environmental specifications identified in Appendix A in the rear of this manual.
Do not apply any unnecessary pressure to the screen area of the monitor. Severe pressure applied
to this portion of the monitor could result in damage or failure of this screen.
All equipment not complying with IEC 60601-1 should be placed outside the patient
environment. Only connect IEC 60601-1 compliant equipment to this monitor. To avoid
potentially hazardous leakage currents, always check the summation of leakage currents when
several items of equipment are interconnected.
For proper equipment maintenance, perform the service procedures at the recommended intervals
as described in the monitor’s service manual.
Single use devices should never be reused.
Organic vapors (e.g. from cleaning agents) in sampling line or room air may alter anesthetic agent
readings.
Alcohol in patient's breath may modify the anesthetic agent readings.
vii
Precautions
Electrical Safety
To avoid an electrical hazard, never immerse the unit in any fluid or attempt to clean it with liquid
cleaning agents. Always disconnect monitor from AC Main Power before performing cleaning or
maintenance.
If monitor becomes accidentally wet during use, discontinue operation of the monitor until all
affected components have been cleaned and permitted to dry completely. Contact your local
Invivo representative if additional information is required.
Shock hazard exists if operated without chassis cover. Refer servicing to qualified service
personnel only.
For continued protection against fire hazard, replace fuses with same type and rating only.
Connect the monitor only to a three-wire, grounded, hospital-grade receptacle. The three-
conductor plug must be inserted into a properly wired three-wire receptacle; if a three-wire
receptacle is not available, a qualified electrician must install one in accordance with the
governing electrical code.
Do not under any circumstances remove the grounding conductor from the power plug.
Avoid use of electrical power extension cords. Electrical power extension cords may create a
safety hazard by compromising the grounding integrity of the monitor.
None of the monitor interconnection ports on the rear of the monitor (e.g. Communication Ports,
Auxiliary Input/Output port [AUX I/O], ECG Sync Input [ECG SYNC IN], Keyboard or Video
Input) are intended for direct patient connection. An electric shock hazard can exist if the patient
is electrically connected to any of these connections.
This monitor and its listed accessories may be safely powered by the voltages 110-120/220-240
VAC having a frequency of 50 or 60 Hz.
If the integrity of the earth ground conductor of the AC mains power cable is in doubt, operate the
monitor on internal battery power until proper earth ground connection is confirmed.
Patient Safety
Constant attention by a qualified individual is needed whenever a patient is under anesthesia or
connected to a ventilator. Some equipment malfunctions may occur in spite of equipment or
monitor alarms.
Always test sampling line adapter for a tight connection and proper operation before attaching to
a patient.
As with all medical equipment, carefully route patient cabling to reduce the possibility of patient
entanglement or strangulation.
Occupational Safety
Connect the sample gas outlet on the monitor's rear panel to a scavenging system to prevent
pollution of room air.
Handle the Patient Sampling Line and its contents as you would any body fluid. Infectious hazard
may be present.
MRI Use Precautions
Certain components of this device will be affected by the magnetic and radio frequency fields present
in your MRI System. Confer with your MRI physicist and/or Radiology staff to identify the proper
placement and use areas for the monitor and its accessories, as defined on the monitor or accessory
labeling. Failure to properly place the monitor and its accessories in the Magnet Room will result in
monitor failure, and possible patient or user injury. Always position the 3160 MRI Physiological
Monitoring System at, or outside, the 5000 Gauss (0.5T) field line of the MRI system. A slight
distortion of the MRI magnetic field homogeneity or possible damage to either the monitor's NIBP or
EtCO2 pump could occur.
viii
Precautions
MRI Use Precautions (Continued)
Always verify proper communicationof the 3160 MRI Physiological Monitoring System with
the Remote Monitor prior to patient use.
MRI Magnet Room Placement. The 3160 MRI Physiological Monitoring System is designed to be
used in conjunction with a remote monitor. The 3160 MRI Physiological Monitoring System is
specially designed not to interfere with MRI operations and may be used inside the MRI Magnet Room
in any location at or outside the 5000 Gauss (0.5T) Field Line of the MRI System. If brought closer
than the 5000 Gauss Field Line, the NIBP monitor pump and EtCO2 pump may fail to operate.
The Remote Monitor is also specifically designed not to interfere with MRI operations, and may be
used in the Magnet Room at or outside the 1000 Gauss (0.1T) Field Line of the MRI System. If
brought closer than the 1000 Gauss Field Line, monitor damage (failure to operate) may result.
Risk of RF current burn. Cables which become inadvertently looped during MRI act as conductive
lines for RF induced currents. When lead wires or other cables form a conductive loop in contact with
the patient's tissue, minor to severe burning can result.
Perform the following to minimize risk of RF current burn:
a. Place cables and lead wires neatly in straight alignment with no looping.
b. Keep the length of lead wires and patient cable within the bore to a minimum.
c. RF burn risk increases when multiple sensors/cables are in use. Such combinations are
not recommended.
d. The high radio frequency (RF) power used in MRI scanning poses an ever-present risk
of excessive heat at the monitoring sites and, therefore, the risk of RF current burn.
Should power levels greater than S.A.R. of 4 w/kg peak (0.4 w/kg average) be
used, the risk of patient burn greatly increases. As a result, monitoring of ECG at
power levels of greater than 4 w/kg peak (0.4 w/kg average) is not recommended for
the general patient population. Such monitoring should only be attempted on conscious
patients with good temperature reflex so they may warn the operator of excessive heat
at the monitoring sites.
e. High RF Power may cause patient heating or burns. For scans with average S.A.R. > 1
w/kg, limit scan time to 5 minutes and pause at least 3 minutes between scans to allow
ECG Cable to cool.
MRI Compatibility
The Quadtrode® MRI ECG Electrode Pad, and ECG Patient Lead Wires and Cable, are compatible
with Magnetic Resonance Imaging (MRI) Systems within the following guidelines:
• MRI systems with static magnetic field strengths up to 1.5 Tesla.
• Usable within the MRI system bore with Specific Absorption Ratios (S.A.R.'s) up to 4.0 w/kg
(peak). Use with higher S.A.R.'s greatly increases the risk of patient burns.
• Non-Magnetic materials are used in the construction of these assemblies.
• If scanned directly across the plane of the ECG electrode element, a slight image distortion may
be seen at the skin surface where the electrode element is positioned.
ix
Precautions
ECG
An inoperative ECG monitor is indicated by absence of an ECG waveform and a simultaneous
Lead Fail alarm.
For best ECG, Heart Rate, S-T Segment, and/or Respiration monitoring, always select the
optimum lead configuration which has the least artifact and largest waveform(s) being detected
for monitoring use.
Failure to respond to a Lead Fail alarm will cause a lapse in your patient’s monitoring. Always
respond promptly to this and any other alarms.
Heart rate values may be adversely affected by cardiac arrhythmia, or by operation of electrical
stimulators.
NIBP
Always use recommended NIBP cuffs and hoses. Avoid compression or restriction of NIBP cuff
hose.
When using the NIBP portion of this instrument to measure blood pressure, remember that the
patient’s blood pressure readings are not continuous, but are updated each time a blood pressure
measurement is taken. Set a shorter interval for more frequent updating of the patient’s blood
pressure.
Do not attach the cuff to a limb being used for infusion. Cuff inflation can block infusion, possibly
causing harm to the patient.
Frequent NIBP measurements can cause pooling of the blood in the limb (hemostasis), and
peripheral tissue/nerve damage. Allow sufficient time between measurements for blood
recirculation to prevent pooling of the blood in the limb.
Arrhythmic and/or erratic heart beats (or severe motion artifact, such as tremors or convulsions)
can result in inaccurate readings and/or prolonged measurements. If questionable readings are
obtained, re-check patient’s vital signs by alternate means before administering medication.
To prevent possible nerve damage to the limb, apply the NIBP cuff as recommended by current
American Heart Association (AHA) guidelines for blood pressure monitoring.
To ensure accurate and reliable measurements, use only recommended patient cuffs/hoses. For
best accuracy, use the appropriate cuff size for each patient as recommended by the current AHA
guidelines for blood pressure monitoring.
Always tighten the cuff air hose connections snugly into place for proper operation.
Some reusable NIBP cuffs contain a medical-grade latex rubber. Patients sensitized to latex
rubber can have an allergic reaction when exposed to this material. Avoid the use of cuffs which
contain latex rubber on patients who are allergic to this material.
Routinely inspect the cuff and hose assemblies for proper attachment and orientation. Replace
cuff and/or hose assemblies with cracks, holes, tears, cuts, etc. that could cause leaks in the
system. If cuff and/or hose assemblies with damage which could result in leaks are used,
prolonged and/or inaccurate patient readings could result.
To prevent skin abrasion, apply and remove cuff carefully. Keep Velcro® (hook and latch)
retention areas away from the skin.
x
Precautions
SpO2
Avoid placement of the SpO2 sensor on the same limb with an inflated blood pressure cuff. Cuff
inflation could result in inaccurate readings and false alarm violations.
SpO2 monitoring requires the detection of valid pulses to correctly determine SpO2 and Heart
Rate values. During conditions of gross artifact, or in the absence of valid pulses, the SpO2 /rate
values may not be correct.
The SpO2 monitoring portion of this monitor is intended to measure arterial hemoglobin oxygen
saturation of functional hemoglobin (saturation of hemoglobin functionally available for
transporting oxygen in the arteries). Significant levels of dysfunctional hemoglobins, such as
carboxyhemoglobin or methemoglobin, may affect the accuracy of the measurement. Also,
Cardiogreen and other intravascular dyes may, depending on their concentration, affect the
accuracy of the SpO2 measurement.
Always shield the SpO2 sensor from extraneous incident light sources. Such extraneous light can
cause SpO2 reading or pulse detection errors.
Frequently inspect the SpO2 sensor site for possible pressure tissue necrosis during prolonged
monitoring. Reposition the sensor at least every four (4) hours. Special care should be exercised
when tape is used to secure the sensor, as the stretch memory properties of most tapes can easily
apply unintended pressure to the sensor site.
The numeric measurement values are updated every one (1) second on the monitor display.
A pulse oximeter should be considered an early warning device. As a trend towards patient
deoxygenation is indicated, blood samples should be analyzed by a laboratory co-oximeter to
completely understand the patient’s condition.
The pulse oximeter feature in this monitor is designed to display functional SpO2 values.
The pulse oximeter pulsatile waveform is not proportional to the pulse volume, but adjusts the
waveform amplitude as needed for proper viewing.
All monitor alarms are categorized as medium priority, unless otherwise specified.
Arrhythmic and/or erratic heart beats (or severe motion artifact, such as tremors or convulsions)
can result in inaccurate readings and/or prolonged measurements. If questionable readings are
obtained, re-check patient’s vital signs by alternate means before administering medication.
Respiration
When setting up respiration monitoring, always observe and adjust the respiration gain of the
monitor while watching the patient’s breathing efforts before completing selection of the gain
setting. Failure to do this can result in inaccurate readings, or false respiration detection.
End-tidal CO2 (EtCO2)
Verify that the patient’s breathing efforts and timing coincide with the monitor’s waveform before
completion of the patient set-up.
The EtCO2/N2O measurements are automatically pressure compensated over an ambient pressure
range from 576 to 788 mmHg.
The EtCO2/N2O measurement displays the sampled value within 1 second of when the gas was
sampled.
The alarm tone volume exceeds 60 dBA at a distance of 1 meter when the alarm tone volume
adjustment is set above selection number 8.
Frequently inspect the EtCO2 patient tubing for proper gas flow. Avoid kinking of the EtCO2
patient tubing that can result in leaking, reduction, or cut-off of the sample gas flow. Inaccurate gas
measurements could result.
xi
Precautions
End-Tidal CO2 (Continued)
EtCO2 patient tubing and its associated components are intended for single-patient use only.
Avoid cleaning or disinfecting these items for reuse. Inaccurate gas measurements could result.
To prevent inaccurate or missed readings, keep the EtCO2 patient tubing clear of any moving
mechanisms which may kink, cut or dislodge the patient tubing.
Do not overtighten the patient gas sample line to the water trap connector. Overtightening this
connector can cause failure of the water trap assembly and resultant inaccurate (artificially low)
patient gas measurements.
Avoid connecting the EtCO2 calibration gas canister to the monitor by any method other than
with the designated calibration tubing. Connecting by any other method could invalidate the
calibration, and/or damage the monitor.
Respiration rate measurement errors could result during ventilation rates above 80 breaths per
minute.
Anesthetic Agents
Inadequate ventilation of the monitor may cause inaccurate readings or damage to electronic
components.
Ensure that the exhaust gas is not removed from the monitor under too strong a vacuum. To
prevent this condition, there must always be an opening to the room air. Too high a vacuum level
may change the operating pressure of the monitor and cause inaccurate readings or internal
damage.
Inspect waste gas line for deterioration on a regular basis. Replace as needed.
Remove sampling line from patient airway whenever nebulized medications are being delivered.
Use only Invivo sampling lines and accessories; other sampling lines may cause inaccurate
readings and malfunctions.
Some Hydrocarbons (e.g. Acetone, Methane) may cause a mixed agent alarm to occur.
Replace the sampling line and inspect water trap between each patient use.
Do not overtighten the patient gas sample line to the water trap connector. Overtightening this
connector can cause failure of the water trap assembly and resultant inaccurate (artificially low)
patient gas measurements.
Routinely inspect the hose assemblies for proper attachment and orientation. Replace hose
assemblies with cracks, holes, tears, cuts, etc. that could cause leaks in the system. If hose
assemblies with damage which could result in leaks are used, prolonged and/or inaccurate patient
readings could result.
If questionable anesthetic agent gas measurements are observed, recheck patient connections,
anesthesia gas machine and/or vaporizer before re-adjusting anesthesia delivery.
Routinely verify the monitor’s internal barometric pressure reading with local conditions during
the initial start-up period.

Precautions
Anesthetic Agents (Continued)
With no gas reading (Agent Icon box with white X for agent identification and agent values of “--
-”) when Agent Vaporizer is first turned on, it may take 30 seconds to 1.5 minutes for agent
identification and reading to be displayed. Once identification is established, changes in
concentration are virtually immediate. With a 200% change in concentration, an auto Zero will
occur, and full accuracy of the changed concentration will be accomplished within approximately
30 seconds.
Whenever the 3160 MRI Physiological Monitoring System Agent sensor changes from steady state
condition, the 3160 MRI Physiological Monitoring System will perform an auto zero to restabilize
the sensor readings. During this time, 15 seconds to 1.5 minutes, it is possible for a false
identification and concentration value to occur. Examples are as follows:
a. No gas, during warm-up and when sample line is disconnected.
b. Applying sample line for the first time.
c. When switching from one Agent to another.
d. Applying N2O in concentrations of 70% or more.
e. Going from N2O of greater than 50% to 0%.
f. When going from high Agent concentrations to low or off.

SECTION 1
INTRODUCTION
1.0 INTRODUCTION.
This manual describes a fully configured monitor, and may include features and/or options that
are not included in your monitor. For additional information, contact your local sales
representative, or Invivo Customer Service.
1.1 Product Description. The Model 3160 MRI Physiological Monitoring System is designed
to assist clinicians in monitoring patient vital signs in the midst of the dynamic and evolving Magnetic
Resonance environment. A combination of the latest wireless communication, radio frequency (RF)
shielding, digital signal processing (DSP), and adaptable mounting technologies address the challenges
associated with patient monitoring in the MRI area. Built on Invivo’s strong heritage in MRI patient
vital signs monitoring, the 3160 provides accurate, continuous, and reliable performance during all
phase of MRI applications.
The standard 3160 configuration consists of wireless electrocardiogram (ECG), wireless pulse
oximetry (SpO2), and non-invasive blood pressure (NIBP). Optional parameters include end-tidal
CO2 and anesthetic agents.
The 3160 system consists of the following components:
a. Wireless Processing Unit. The Wireless Processing Unit (WPU) houses the
circuitry and hardware for support of the standard and optional patient monitoring
parameters. The transceivers and antennas that support wireless communication
with the ECG and SpO2 modules as well as the Display Controller Unit are also
part of the WPU. The unit is powered by an AC – DC power adapter or two
removable batteries that are recharged by the same power adapter. The batteries
provide 8 hours of continuous operation.
b. Patient Connection Unit. The Patient Connection Unit (PCU) contains the
connectors that support all the non-wireless parameters (i.e. NIBP, EtCO2, etc.)
c. Display Controller Unit. The WPU communicates to the Display Controller Unit
(DCU) via a bi-directional 2.4 GHz communication link. The large color LCD
display, keypad, and recorder of the DCU form an easy-to-use user interface for
display, control, and documentation of the system patient monitoring parameters.
d. Wireless ECG Module. The Wireless ECG (WECG) module communicates two
leads of ECG simultaneously to the WPU. These two leads of ECG can be
displayed at the DCU and are output from the WPU unit for interface to the MRI
system cardiac gating input.
e. Wireless SpO2 Module. The Wireless SpO2 (WSpO2) communicates the SpO2
value and pulse waveform to the WPU. The information is available for display at
the DCU and is output from the WPU for interface to the MRI system pulse
peripheral gating input.
1.1.1 System Mounting. The Model 3160 MRI Physiological Monitoring System is built upon an
adaptable mounting platform where the system can be configured in a traditional pole mount
configuration or mounted directly onto the MRI table. The MRI table mount provides an effective
means of allowing the Model 3160 to travel along with the patient on the MRI table thus improving
throughput and efficiency.
1.1.2 System Parameters. The 3160 MRI Physiological Monitor System Parameters allow
simultaneous processing and display of up to five (5) parameters, three (3) waveforms and associated
numeric values from each different parameter. All the Patient Information is clearly displayed on a Flat
Panel Display Screen.
1-2
The 3160 MRI Physiological Monitoring System includes the following Vital Sign
Parameters:
1.1.3 User Interface. A simple to use interface has been developed to minimize operator learning
time. On the Display Control Unit (DCU), there is a Rotary Knob (which detents from selection to
selection) that is used to access the parameter menu's, access the various setup features and finalize any
changes to the setup of the monitor. Frequently used menus (such as: Alarms, Trends and Recorder)
have a Control Key which, when pressed, will open the associated menu. On the Wireless Processor
Unit (WPU), the operator needs an external display and a keyboard to access the various features.
1.1.4 Versatility. With its diverse offering of vital sign parameters, the 3160 MRI Physiological
Monitoring System may be configured to meet the monitoring needs of a wide spectrum of patients
from Neonate to Adults. Every available parameter may be easily accessed and adjusted to the unique
needs, condition and situation of each patient.
1.2 Wireless Processor Unit (WPU). The WPU contains wireless transceivers, data acquisition
and processing circuitry that communicate with the wireless Display Control Unit (DCU), ECG
(WECG) module and SpO2 (WSpO2) module.
1.2.1 Operating Environment. The WPU is designed to operate at the 5,000 Gauss line in the
generated RF field of an MRI system measured from the center line of the bore.
1.2.2 Power Supply. The WPU Power Supply is designed to operate on the floor at least 10 feet
from a 1.5 Tesla unshielded MRI system (200 Gauss). When attached, the power supply charges the
WPU battery pack whether the WPU is operating or not.
1.2.3 Battery Operation. The WPU will operate at least eight (8) hours with EtCO2 and all optional
devices running with NIBP performing automatic readings at five (5) minute intervals.
Figure 1-1. Patient Connection Unit (PCU)
1.3 Patient Connections. The physical patient connections for NIBP and the Anesthetic Agents
options are located on the Patient Connection Unit (PCU, See Figure 1-1). ECG, SpO2 and
Respiration all use wireless technology to deliver their measurements to the Wireless Processor Unit
(WPU).
1.3.1 NIBP and Agent Monitoring. The PCU contains the physical connections for the Non-
Invasive Blood Pressure (NIBP) and, when installed, the optional Anesthetic Agents parameters. If
Anesthetic Agents is installed, the PCU also contains a water trap to prevent moisture contamination of
the agent components.
a. Operating Environment. The PCU is designed to operate at the 5,000 Gauss line in
the generated RF field of an MRI system measured from the center line of the bore.
• Single Lead ECG • Pulse Oximetry • NIBP
• EtCO2 • Respiration • Anesthetic Agents
1-3
1.3.2 ECG Monitoring. ECG is monitored using an ECG Telemetry Transmitter (WECG). The
Wireless ECG Module consists of a wireless transceiver to communicate with the WPU and convert
the ECG signals into radio signals for transmission to the Wireless Processor Unit. The module also
receives information through the wireless link, converts the information to electrical signals and
performs the commanded task (i.e. lead configuration change, scaling, etc.).
a. Compatability. The Standard Wireless ECG Module supports the four ECG electrode
placement used with the Quadtrode (Part # 9303), Quadtrode CV, Neonatal Quadtrode
and MRI ECG Patient Cable and Lead wires (Part # 9340) for display of Lead II.
b. Visual Indicators. The WECG module contains one (1) bi-color LED that indicates
the status of the battery charge.
c. Battery Life. The WECG module will operate at least eight (8) hours on a fully
charged battery.
1.3.3 SpO2 Monitoring. SpO2 is monitored using a SpO2 Telemetry Transmitter (WSpO2). The
Wireless SpO2 Module consists of a wireless transceiver to communicate with the Wireless Processor
Unit and convert the SpO2 pulse signal into radio signals for transmission to the Wireless Processor
Unit (WPU).
a. Visual Indicators. The WSpO2 module contains one (1) bi-color LED that indicates
the status of the battery charge.
b. Battery Life. The WSpO2 module will operate at least eight (8) hours on a fully
charged battery
1.4 Display Control Unit (DCU). The DCU provides control and display of the monitored
parameters. Control of the Monitoring Features is provided through the use of a Rotary Knob; as the
operator turns the Rotary Knob (either clockwise or counterclockwise), with each detent the next
Menu-Select Icon (Vital Sign Numerical Display) will become highlighted (selected) and, when the
appropriate display is selected, pressing the Rotary Knob will bring up the menu for that parameter.
For control and adjustment of the operation and features, the Keypad contains three separate sets of
pushbutton keys which contain both operational and menu-select keys.
1.4.1 DCU Controls. (See Figure 1-2) The DCU front panel contains all the controls and access for
complete patient monitoring. Control is provided by the pushbutton keys and Rotary Knob. The
following is a general description of the DCU.
Figure 1-2. The Front Panel
1-4
a. The Rotary Knob. The Rotary Knob is located to the right of the Display Screen. The
function of the Rotary Knob is menu specific. For this reason, its various functions are
described throughout this document where it is used; in general, however, the Rotary
Knob operates as described below:
(1) As the Rotary Knob is rotated, either clockwise or counterclockwise, the
monitor display “scrolls” through the various screen items (screen icons, menu
options and patient parameters) which are available for selection. When the
appropriate item is “highlighted,” it may be selected by pressing and releasing
the Rotary Knob. All menus have a RETURN option which will return the
monitor to the previous menu selection.
(2) During normal operation each active parameter has a Menu-Select icon on the
screen. When the Rotary Knob is rotated, the Menu-Select icon which is being
pointed at becomes “highlighted.” Rotating the Rotary Knob will cause the
monitor to “scroll through” the available menu selections. Once the appropriate
Menu-Select icon is highlighted, pressing the Rotary Knob completes the
selection and brings up the required menu. Once the menu is selected, the
Rotary Knob is used to scroll through the available choices and make
adjustments to the selected parameter. The following Menu-Select Icons may
be available on the Normal Screen (depending on which parameters are
available, enabled and turned on): ECG, NIBP, SpO2, EtCO2 and Agents.
Figure 1-3. The Top Keypad Set
b. The Top Keypad Set. (See Figure 1-3) There are six push keys in the top keypad set.
The top three (FREEZE, EVENT MARK and ZERO ALL) provide direct control of
a monitor feature while the bottom three (SETUP, ALARMS SCREEN and
RECORDER SETUP) provide access to operational menus. The six push keys are
described below:
(1) FREEZE. The 3160 MRI Physiological Monitoring System freezes the
ECG waveform from Trace A for closer examination upon user demand.
When the ECG trace is active, pressing the FREEZE key will freeze it into the
Trace B location while Trace A remains active. When the trace is frozen,
pressing the FREEZE key will release it. A “Blue Box” appears around the
frozen waveform as a visual indication that the waveform is not active. While
the Freeze feature is active, the monitor will not allow any changes to the
Parameter Setups or Display; if the operator attempts to access the
PARAMETER SELECTION menu, a WARNING Box alerts the operator
that entry to the selected menu is not allowed while FREEZE is enabled.
(2) EVENT MARK. The EVENT MARK key prints a marker on the ECG
Recorder Strip when the printer is running. If the printer is not running,
pressing this key has no effect.
(3) ZERO ALL. This feature is not available. Pressing this key will display a
dialog box that alerts the operator that no Invasive Pressures are enabled.
(4) SETUP. The SETUP key allows the operator to access the various available
setup options.
1-5
Figure 1-4. The Middle Keypad Set
c. The Middle Keypad Set. (See Figure 1-4) The middle keypad set contains six push
keys. The three on the left provide control of the NIBP monitoring feature with two of
the keys (NIBP START/STOP and NIBP STAT) providing direct control of NIBP
measurements and the third (NIBP INTERVAL) bringing up a menu that allows
adjustment of the NIBP auto mode interval feature. On the right side of this set are two
keys which control the Trending feature of the monitor (TRENDS and CLEAR
TRENDS) while a third (RECORD) provides a hardcopy printout of selected
parameters as specified by operator adjustments in the RECORDER Menu. The six
push keys are described below:
(5) ALARMS SCREEN. The ALARMS SCREEN key is a dual function key
that allows the operator to setup the Alarms monitoring feature. When the
monitor display is in the Normal Screen and the ALARMS SCREEN key is
pressed, the Main Alarm Setup Screen will appear; when the monitor display
has any icon highlighted and the ALARMS SCREEN key is pressed, an
Alarm Setup Screen for the highlighted parameter appears.
(6) RECORDER SETUP. The RECORDER SETUP key allows the operator
to setup the Recorder option.
(1) NIBP START/STOP. This key starts a new NIBP measurement, or stops a
measurement that is already in progress..
(2) NIBP INTERVAL. Pressing the NIBP INTERVAL key brings up the NIBP
INTERVAL Menu where the cycle time (time between readings) of the NIBP
Automatic Reading Mode may be adjusted.
(3) NIBP STAT. This key starts the NIBP STAT Mode measurements. This
mode may be terminated by depressing the NIBP START/STOP key. The
STAT Mode performs up to five (5) NIBP measurements in rapid succession
(with a short pause between readings) within a maximum time frame of five
(5) minutes.
(4) TRENDS. The TRENDS key allows the operator to setup the Trend
monitoring feature. The exact operation of the TRENDS key is based on
whether or not a feature is currently highlighted. If a feature is currently
highlighted, pressing the TRENDS key will bring up a Trend which is specific
to the highlighted feature; if a feature is not currently highlighted, pressing the
TRENDS key will bring up the HISTORY Menu and Tabular Display (See
Section 5).
1-6
Figure 1-5. The Bottom Keypad Set
d. The Bottom Keypad Set. (See Figure 1-5) The bottom keypad set is not grouped like
the top and middle, but are grouped around the Rotary Knob. There are three push keys
in this set (NORMAL SCREEN, STANDBY and ALARM SILENCE) which
provide direct control of operational features of the monitor. The three push keys are
described below.
(5) CLEAR TRENDS. Pressing the CLEAR TRENDS key allows the operator
to clear all the stored data from memory. To prevent accidental erasure of
patient data, there is a Yes/No box associated with this key that appears to
ensure that the operator meant to clear the trend data.
(6) RECORD. Pressing this key records the Single Trace or Dual Trace selections
(as specified by operator adjustments made in the RECORDER Menu).
The recorder stops automatically after approximately 30 seconds, or when the
RECORD key is pressed again; in either case, the printout ends with a “Snap
Shot” of the active patient parameter data.
(1) NORMAL SCREEN. Pressing the NORMAL SCREEN key returns the
3160 MRI Physiological Monitoring System from any menu to the normal
screen.
(2) STANDBY. Pressing the STANDBY key places the 3160 MRI
Physiological Monitoring System into the Standby Mode. The monitor stays
in Standby Mode until the STANDBY key is pressed a second time. Except
for the three (3) key features given below, the monitor operates normally by
continuing to provide current patient information on the Display Screen.
While in Standby Mode:
• All audible alarms and nurse call are disabled. The disabled alarms
are indicated on the screen by the “X” through the bell shaped
Alarm Status Symbol.
• Active NIBP automatic measurements and STAT Mode
measurements are suspended.
• No automatic printout is generated.
• Default NIBP inflation pressures will be used for all manual NIBP
readings.
1-7
(a) Alarm Silenced. Any new alarm conditions will cause the Alarm to
reactivate and will also activate the Nurse Call Alarm.
In addition, while alarms are silenced the following conditions
apply:
•Unlatched Alarms. If the alarm system has been set to
UNLATCHED in the ALARMS Menu and an Alarm Limit
is violated, pressing the ALARM SILENCE key will
silence the Alarm Tone turns off the Nurse Call Alarm and
puts the letter “S” in the Alarm Bell when an active Alarm
Limit has been violated. While the parameter continues to
violate its limits, the numerics of the violating parameter
continue to flash on the screen.
•Latched Alarms. If the alarm system has been set to
LATCHED in the ALARMS Menu and an Alarm Limit is
violated, while the parameter continues to violate its limits,
pressing ALARM SILENCE key stops the Alarm Tone,
but the numerics remain red and continue to flash, even
after the parameter returns to within its Alarm Limits.
•ALARM HOLD. If the ALARM SILENCE key is pressed
when the Alarm Tone is enabled but no alarm condition
currently exists, a “SOUND ON HOLD” message appears
in the upper center of the screen with a count down timer
starting at 180 (counting down at a 1 second rate) denoting
that the Alarm Tone is being temporarily held silent. In
addition, an “H” will appear in the Alarm Status Symbol to
further alert the operator that the Alarm System is on Hold.
If the Alarm Tone is sounding, the first pressing of the
ALARM SILENCE key stops the Alarm Tone, turns off
the Nurse Call Alarm, and puts the letter “S” in the Alarm
Bell, and a second pressing enables Alarm Hold.
The monitor automatically exits alarm hold after three
minutes, and the “SOUND ON HOLD” message
disappears from the screen, reactivating the Alarm Tone
(remember that a current alarm condition, which has been
silenced, will not sound again unless the condition returns
within limits and then violates the limit again. Also
remember that a silenced alarm may not be accompanied by
the Alarm Silence message). Pressing the ALARM
SILENCE key before the three minute period is over will
also reactivate the Alarm Tone and nurse call alarm and
remove the “SOUND ON HOLD” message from the
screen.
(3) Alarm Silence Key. Pressing the ALARM SILENCE key, when the audible
alarms are enabled (as denoted by the absence of the “X” through the bell
shaped Alarm Status Symbol), will affect the monitor as described below:
WARNING
An active silenced alarm may not be accompanied by an Alarm Silence message or an “S” in the
Alarm Bell icon if the Alarm Hold sequence has been activated, or if a subsequent additional alarm
has occurred and self-corrected.
1-8
The user is able to put alarms on hold (SOUND ON
HOLD) only when the Alarm Tone is active (no X appears
in the bell symbol in the upper left of the screen). Alarm
Hold is useful for temporarily disabling the Alarm Tone.
This might be useful, for example, when changing ECG
leads or for any user activity which might cause a “false”
alarm.
1.4.2 DCU Display. The DCU display screen (See Figure 1-6) displays four groups of data: 1) the
Informational Display, 2) the Vital Signs Trace Display, 3) the Vital Signs Numeric Display and 4) the
Status Display. The entire display screen, with its four different display groups, is called the “Normal
Screen.” The four display areas are described below.
Figure 1-6. The Normal Screen
a. Informational Display. (See Figure 1-7) The Informational Display is located at the
top of the Normal Display. This display provides the operator with the current time, the
Alarm Status Bell Symbol, a flashing Heart Rate Symbol, a flashing Lung Symbol, any
current user messages and the current Patient Selection.
Figure 1-7. The Informational Display
(1) Time. The current time is displayed in a 12 or 24 hour format (hh:mm:ss). The
time, date and clock mode (12 or 24 hour) is adjusted in the TIME Menu.
(2) Alarm Status Symbol. The 3160 MRI Physiological Monitoring System
sounds an Alarm Tone when any monitored parameter violates its
programmed Alarm Limits. The status of the Alarm Tone is indicated by the
bell shaped Alarm Status Symbol.
WARNING
When an “X” appears in the Alarm Status Symbol, the audible Alarm Tone will NOT sound for any
reason.
1-9
(a) The letter “H” appearing in the bell indicates that the alarms have been
placed on temporary Hold with the ALARM SILENCE key.
Similarly, during power-up the “SOUND ON HOLD” message
displayed in the center of the screen indicates that the Alarm Tone is
temporarily placed on hold. A 180 second countdown timer is also
displayed under the message.
(b) The letter “X” appearing in the bell symbol indicates that the alarms
have been turned off from the ALARMS Menu or that Standby Mode
has been engaged. In this case the Alarm Tone will not sound for any
reason.
(c) The letter “S” appearing in the bell indicates that a current alarm has
been silenced with the ALARM SILENCE key. This feature will
disable only the alarms that were current when the ALARM
SILENCE key was pressed, any new alarms will cause the Alarm
Tone to sound.
(3) Heart Symbol. The Heart Symbol flashes on the screen each time a heart beat
is detected. A tone is sounded at the same time (unless turned off in the ECG
Menu or the SPO2 Menu).
(4) Lung Symbol. The Lung Symbol flashes on the screen at the end of each
detected breath whenever the EtCO2 monitoring feature is turned on (if
available).
(5) Messages. These messages assist the operator in various aspects of the
operation of this monitor.
(6) Patient Selection. Indicates the selected patient (ADULT or NEONATAL) for
the ECG and NIBP monitoring features.
Figure 1-8. The Vital Signs Trace Display
b. Vital Signs Trace Display. (See Figure 1-8) The Vital Signs Trace Display is located
in the middle of the Display Screen. This Display provides the operator with a trace of
the selected parameters and also contains Numerical Vital Sign indications for the
selected patient parameter.
(1) The Vital Signs Trace Display portion of the screen is divided into six separate
trace areas. When turned on, the traces are fixed on the screen and updated with
an Erase Bar. When a trace has been turned off, that portion of the screen is
blank. The numeric values for each trace appear near the right screen
boundary.
(2) If the value is greater than or equal to a maximum calculable value, “OVR”
(Over Range) is alternately displayed with the numeric value.
1-10
(3) TRACE A, C and D are assigned according to parameter and come on/go off
as parameters are turned on or off. Trace B is the location used for the
“Freezing” of a waveform and is not assigned a parameter.
The following is a description of each Trace:
(4) TRACE A. The ECG trace is displayed in this position, unless turned off from
either the ECG Menu or the SETUPS Menu. The main menu for this trace and
for the Heart Rate are brought up with the selection of the ECG Menu-Select
Icon.
(a) The heart rate is displayed near the right screen boundary in the Trace
A position. The numerics turn Red and flash if a Heart Rate Alarm
Limit is violated. The color of the numerics is that of the selected HR
source.
(b) The annotation below the heart rate value indicates the source of the
heart rate, as selected from the ECG Menu, the NIBP Menu and the
SPO2 Menu. Heart rate source choices are AUTO, ECG, SPO2 and
NIBP (there is an ART option shown but selecting this item will bring
up a message alerting the operator that the option is not available).
(c) A red flashing numeric value on the screen indicates that an alarm for
this value has been violated. This provides a visual indication of alarm
violations, even when the Alarm Tone is turned off.
(d) If AUTO is selected as the HR SOURCE, the highest-priority active
input is utilized for displaying the heart rate, in the order listed above.
The ECG trace must be off, or lead fail present, for the Auto source not
to be the ECG trace.
(e) If the monitor does not find a valid heart rate source when set to
AUTO and NIBP is OFF, the heart rate is annotated with “NONE.”
(f) The displayed lead for the ECG 1 is indicated near the left screen
boundary.
(g) A scale indicator is displayed near the left screen boundary in the ECG
waveform area(s). It represents a 1mV amplitude in the currently
selected scale.
(5) TRACE B. Trace B displays a frozen waveform for detailed analysis.
(6) TRACE C. Trace C displays the SpO2 waveform (if SpO2 enabled).
(7) TRACE D. Trace D displays the Respiration waveform (if EtCO2 enabled).

c. Vital Signs Numeric Display. (See Figure 1-9) The Vital Signs Numeric Display is
located at the bottom and right of the display screen. This Display is divided with
boxes that provide the operator with numerical indications for NIBP and Agents.
1-11
The following is a description of the NIBP and Agents boxes.
(1) Non-Invasive Blood Pressure (NIBP). NIBP is the first parameter (from the
left) displayed in the Vital Signs Display. The Systolic, Diastolic and Mean
blood pressure values are displayed along with measurement information such
as the Elapsed Time (ET) since the last measurement and the time until the
next measurement (if in the Automatic Mode). While in the Manual mode,
MANUAL is shown in the place of the time until the next measurement.
During a reading cycle the current cuff pressure is displayed (“CUFF: XXX”).
Between the measurements the elapsed time (time since the last reading) is
displayed (ET= 00:00:00) instead of the cuff pressure.
The NIBP error messages are shown in place of the “NEXT: 00:00:00.” If
errors are detected by the NIBP circuitry, one of the following messages are
displayed which preclude the determination of the blood pressure:
(a) OVER PRES: Cuff inflation pressure has exceeded 280 ±5 mmHg.
(b) CALIB: Monitor has detected DC offset below 1 mmHg or above 11
mmHg.
(c) NOT INFLATING: Cuff inflation runs longer than 30 seconds.
(d) LONG PRES: Cuff pressure remains at one level for more then 30
seconds.
(e) CUFF LEAK: The cuff inflation pump has run for more than 20
seconds. Check hose and cuff connections.
(f) RESID PRES: Cuff pressure above 20 mmHg for more then 180
seconds.
(g) WRONG CUFF: The wrong cuff is attached for the patient setting.
Select Adult or Neo (as appropriate) in the SETUPS Menu.
(2) Agents. The Agents box is in the middle of the Normal Screen. This box
displays the numerical values for a wide variety of anesthetic agents. Most
Anesthetic Agents are identified and specified by name next to the numerical
value for the gas being measured.
d. System Status Display. The System Status Display is located at the very bottom of the
Normal Display and provides the operator with visual indications of the operational
status of the system. From left to right the symbols are the DCU Battery Status symbol,
the WPU Communication/ Battery Status symbol and the Network symbol.
(1) DCU Battery Status. This symbol is currently inactive. In the future it will
provide a visual indication of the DCU Battery Charge Status.
(2) WPU Communication/Battery Status Symbol. This symbol is currently
only partially active. In the future it will indicate the Battery Status of the
WPU. Currently it indicates the status of the communication link between the
DCU and WPU by replacing the normal symbol of the Bed and Battery with
one of the Bed boxed in red with a red X through it.
(3) Network Symbol. This symbol provides the Network Designation for the
wireless link. It is important that networked units are correctly identified to
avoid the unintentional interference with a patient on another network of
monitors. This symbol aids the identification of the selected network by
providing three different indications with shapes, colors and numbering all
used to identify specific networks.
1-12
e. Front Panel Power Light. (See Figure 1-5) The Front Panel Power Light (located
beneath the Rotary Knob) is a three color LED that indicates the AC/Battery Power
condition of the monitor. The Power Light will illuminate Green, Yellow and Red as
described below:
(1) Green Light. A Green Light indicates that the monitor is connected to AC
Line Power and that the internal battery circuitry is operational. In normal
operation, this light will be illuminated Green.
(2) Yellow Light. A Yellow Light indicates Caution because the monitor is
operating on the internal batteries.
(3) Red Light. A Red Light indicates Warning because monitor shutdown is soon
to occur. The internal batteries have fallen below the required operational
output and an AC Wall Outlet should be located, and the monitor plugged into
it through the AC Power Adapter, immediately.
f. Yes/No Menu. In various menus, the operator may accidentally make a selection that
has significant irreversible effects (e.g.: erasing patient data). To protect against such
accidents a Ye s / N o Menu is associated with these selections. This menu has only two
active selections: YES and NO. The operator must select one of the two choices to
either confirm the change to take place, or to cancel it. A delay of approximately 30
seconds without any selection is equivalent to selecting NO. The Ye s / N o Menu is
removed upon operator selection, at the end of the time-out feature, by pressing the
NORMAL SCREEN button or by pressing the STANDBY button.
1.5 Cleaning. The monitor is not sterilizable. Never immerse the unit in any fluid or attempt to

3.3 Store/Recall Setups. (DCU Only) The 3160 MRI Physiological Monitoring System has
seven (7) memory blocks, each of which has enough capacity for the current setting of every control
setup, alarm limits, trend time base, etc. on the monitor. The operator is able to store and recall seven
different configurations of the monitor. The seventh (USER DEFAULTS) is also used for recall at
monitor power up. The memory blocks are maintained by a long-life battery, or static RAM memory,
which will keep the memory contents intact even when power is off.
Settings for the monitor can be stored for different procedures, different types of patients, etc., or multi-
ple users of the monitor can store and recall their own preferred configurations without having to indi-
vidually set each limit, status, etc., before each use.
Each storage memory block maintains the settings for:
a. ALARMS. The setting of MIN and MAX values. auto-set percentage, latched or
non-latched selection for alarms, and alarm tone enabled/disabled.
b. SYSTEM SETUPS. All Settings.
3-21
c. ECG. Selected lead, scale setting, trace speed, filter mode, QRS tone ON/OFF and
heart rate source.
d. RECORDER. Off or auto, trace delay, recorder speed and the selected traces.
e. NIBP. Manual, off or auto and the automatic time interval.
f. EtCO2. Size, grids and flow.
g. TREND GRAPHS. Time bases and scales.
h. SpO2. Size.
Once the monitor is setup properly, the setups may be stored in one of the available memory blocks.
The stored setups can be brought up via the RECALL SETUPS Menu.
3.4 Monitor Initialization. The monitor may start its monitoring functions from either an initial
(Factory Settings) state or a pre-configured state depending on how the stored configuration
information and patient data (trends, tabular data, and reports) are treated on start-up.

PATIENT PARAMETERS
4.0 PATIENT PARAMETERS.
4.1 ECG Monitoring. Unless it has been turned off in the ECG Menu, the selected ECG lead is
displayed as TRACE A. Most ECG functions are contained in the ECG Menu. Additional features
useful with ECG monitoring are found in three secondary menus:
•RECORDER Menu. Used to select all recorder functions and to set the recorder
and trace speed.
•ALARMS Menu. Used to set and/or disable the ECG alarms. The range of Alarm
Limits for the ECG Heart Rate is 30 to 249 bpm.
•HEART RATE Trend Menu. Used to setup and print Trended information.
For further information on the secondary menus, see the corresponding paragraphs of this
document.
4.1.1 Patient and Lead Preparation. Acquisition of the patient's ECG signal is achieved with a
Invivo approved patient cable with the appropriate lead wires and electrodes. Patient skin preparation,
type of electrode used, and technique used to apply electrodes are major factors that can affect the
quality of tracing displayed on the monitor. To obtain a tracing with baseline stability and to reduce
artifact due to patient movement the following guidelines should be followed.
a. Patient Skin Preparation. Prepare the patient's skin as follows:
• Shave hair from electrode placement sites.
• Cleanse skin thoroughly to remove skin oil, or any other substance that can
increase impedance (avoid using alcohol as it tends to overdry the skin
causing flaking which increases impedance). For best results use Invivo
Skin Prep #9009.
• Gently abrade the skin with gauze or rough material to remove dry skin.
b. Electrodes. Check the electrodes for the following:
• Use electrodes of the same type/brand to ensure consistent impedance
levels.
• Ensure electrodes do not exceed the expiration date.
• Ensure that the conduction gel is moist to the touch.
c. Electrode Placement. Place the electrodes as follows:
• Attach electrodes to the lead wires prior to placing on the patient.
• Place black electrode on left shoulder under left clavicle.
• Place white electrode on right shoulder under right clavicle.
• Place red electrode on lower left abdomen under the sixth rib.
• Place the green electrode on the lower right abdomen under the ribs.
d. Attaching the ECG Cable. Attach the ECG cable to the ECG Patient Connector on
the WECG telemetry transmitter.

If AUTO is selected, a scale is picked that would make the current waveform(s) fill the
ECG viewing area. This scale will be in effect until another scale is selected (AUTO or
any other selection). A Scale Indicator associated with the Trace is displayed on the left
side of the screen, and denotes a 1 millivolt signal amplitude.
(1) If the scale of the ECG trace is so large that the top or bottom of the ECG
waveform is distorted or flattened, the “OVERSCALE” message flashes in
the ECG waveform area. This message will override other ECG error
messages. Use the SCALE menu option (in the ECG Menu) to resize the
waveform until the “OVERSCALE” message stops flashing. If this continues,
the Auto Scale option should be selected to prevent further waveform
distortion.
(2) The ECG waveform in may be frozen for closer examination by pressing the
FREEZE control key. When the waveform is frozen, it is displayed below

(2) RECORDER. Selecting this menu option sends a 1mV pulse calibration
waveform to the ECG Vital Sign and will also be the ECG waveform printed
by the recorder if so configured. The message CAL is displayed over the ECG
waveform on the screen.
(3) ECG. Selecting this menu option sends a 2mV peak to peak (1mV peak)
calibration signal to the ECG vital sign and will also be the ECG waveform
printed by the recorder if so configured. The message CAL is displayed over
the ECG waveform on the screen. It is important to note that this is a hardware
generated calibration waveform and originates as a square wave.
(4) RETURN. Selecting this menu option closes the CALIBRATE Menu.
h. RETURN. Selecting this menu option will return the monitor to the Normal Screen.
4.1.4 Alarm Limits. Alarm Limits may be set two ways. To set the Alarm Limits for every
available parameter, from the Normal Screen (with no icons highlighted), press the ALARMS
SCREEN Menu-Select Key. To set the Alarm Limits for ECG Heart Rate only, highlight the ECG
Icon and press the ALARMS SCREEN Menu-Select Key to access the individual parameter Alarm
Limits Box. The range of Alarm Limits for the ECG Heart Rate is 30 to 249 bpm.
4.1.5 Trended Data. For complete information on the trending of patient ECG data, see Section 5:
Printing and Trending.
4.1.6 ECG Messages. The following is a list of messages that may be displayed during ECG
monitoring:
4.2 Non-Invasive Blood Pressure (NIBP) Monitoring. The NIBP feature measures and
displays systolic, diastolic and mean arterial pressures, and pulse rate. LOW and HIGH Alarm Limits
are available for all three pressures. When the 3160 Vital Signs Monitoring System is configured to
obtain the patient's heart rate from the NIBP, the heart rate alarm is also applicable to this parameter.
The monitor may be set to take NIBP readings at automatic intervals from 1 to 240 minutes (there is a
20 second pause between readings to allow for peripheral perfusion), or the operator can manually
initiate a reading at any time.
When a successful reading is taken, the elapsed time display indicates the beginning of this cycle.
The time until next measurement indicates when the next automatic measurement will be made. A
manual reading does not restart this cycle time. The NIBP INTERVAL key may be used to
adjust the cycle time. The NIBP START/STOP key may be used to manually start/stop a
measurement. The NIBP STAT key allows the start of STAT Mode (which makes up to five (5)
NIBP determinations in rapid succession).
If an error is detected, the Alarm Tone will sound, and an error message will be written on the
screen.
Non-Invasive blood pressure monitors are sensitive to patient motion artifact. Such artifact can
cause readings to be slow or even an incorrect pressure reading.
Visual checks of the patient, other vital signs and checking the limb to which the cuff is attached
should be standard routines with NIBP use.
LEAD FAIL LEAD FAIL is displayed when a faulty ECG Lead is detected by the
system.
OVERSCALE OVERSCALE is displayed if the scale of the ECG Trace is so large
that the tops of the ECG waveforms are being “clipped” (the tops and
bottoms cut off). This message suppresses all other ECG Error
Messages and the Alarm Tone will not sound. To reduce the scale,
and remove the OVERSCALE message, access the SCALE menu
option in the ECG Menu.
4-6
If a measurement is in progress and communication is lost between the DCU and WPU, the
measurement is aborted.
Most NIBP functions are contained in the primary NIBP Menu. However, additional features
useful with NIBP monitoring can be found in the three secondary menus associated with this
parameter:
•RECORDER Menu. Used to select recorder functions and to set the recorder
trace speed.
•ALARMS Menu. Used to set and/or disable the NIBP alarms. The range of Alarm
Limits for the NIBP is 5 to 249 mmHg.
•NIBP Trend Menu. Used to setup and print Trended information.
4.2.1 Theory of Oscillometric Measurement. This monitor obtains blood pressure measurements
based on the Oscillometric principle. Oscillometric Monitors use an inflatable occlusive cuff which
can also be used in the manual auscultatory technique; however, rather than monitoring Korotkoff
sounds, Oscillometric Monitors detect and measure oscillations induced in the cuff by the movement
of the arterial wall. In basic terms, oscillometric monitors utilize a pressure transducer which is
connected to the cuff via a hose. The transducer transforms the oscillations induced into the cuff
pressure into electrical currents. Under control of a microprocessor and software algorithms, the
electrical current can then be measured and correlated with the cuff pressure to determine arterial blood
pressure. The following describes the process of Oscillometric Measurement:
Figure 4-5. Oscillometric Measurement Method
a. As the occlusive cuff is inflated to a suprasystolic pressure the artery is occluded so that
no blood passes through. At this point, even though no blood flows under the cuff,
there are small pulsations induced into the cuff pressure by the partially-occluded
proximal portion of the artery lying under the cuff (See Figure 4-5).
b. As cuff pressure is reduced to just below the systolic pressure, the force of the height of
the systolic pressure wave forces the occluded artery open, blood spurts through the
artery and the amplitude of the oscillations increase sharply. This is the systolic
pressure.
c. With further reduction in cuff pressure the artery opens for a longer time during each
cardiac cycle, which causes increasingly larger oscillations in the cuff pressure until
they reach a point of maximum oscillation amplitude. This point of maximum
oscillations has been well-demonstrated to be Mean Arterial Pressure.
d. With continued cuff-pressure reduction, the underlying artery is open throughout the
cardiac cycle, and the arterial-wall movement is less. The cuff pressure oscillations
begin to decrease in amplitude until they become uniform. The point at which the
amplitudes become uniform is diastolic pressure.
NOTE
The point of maximum oscillations is coincident with mean arterial pressure regardless of arterial
elasticity so long as the ratio of air volume in the cuff to the volume of the artery under compression
does not greatly exceed ten (10) to one (1). For this reason it is advisable to keep the cuff air volume
to a minimum by using the smallest cuff size possible for each patient.
4-7
4.2.2 Patient and Cuff Preparation. The patient should remain calm and motionless while the
monitor is being used. If the patient is overactive, prolonged or inaccurate readings may result.
Perform the following to prepare the patient and cuff for monitoring:
a. Cuff Selection. The cuff is selected and positioned as it would be for an auscultatory
blood pressure determination, and the current guidelines of the American Heart
Association should be followed. The bladder width of the cuff should be 40% of the
circumference of the limb. For a correct fit on adult and pediatric cuffs, the Index line
on the end of the cuff must fall between the two Range lines printed on the inside of the
cuff. For correct fit on neonatal cuffs, choose the size with the stated circumference
range that fits the circumference of the limb of the neonate.
b. Cuff Positioning. The cuff should be wrapped firmly (not snug) around the arm of the
patient and positioned as close to heart level as possible. If the cuff is not at heart level,
add 1.8 mmHg to the displayed readings for each inch that the center of the cuff is
located above the patient's heart level; subtract 1.8 mmHg from the displayed readings
for each inch that the cuff is located below the patient's heart level.
c. Cuff Connections. Select the proper hose (twin-lumen for adults, single-lumen for
neonates), and attach hose to cuff. Route the hose from the cuff to the monitor so it does
not kink, tangle or limit access to the patient.

4.2.8 Stat Mode Operation The STAT Mode is specifically intended for clinicians who need to
obtain successive readings for rapid assessment of the trend of a patient's pressures. To initiate a series
of up to five STAT Readings, the operator presses the NIBP STAT Control Key. The monitor will
perform up to five NIBP cycles in a period of five (5) minutes. At the end of the five (5) minute period,
the STAT Mode will terminate (even if a reading is in progress) regardless of how many readings have
been completed.
4.2.9 Alarm Limits Alarm Limits may be set two ways. To set the Alarm Limits for every available
parameter, from the Normal Screen (with no icons highlighted), press the ALARMS SCREEN Menu-
Select Key. To set the Alarm Limits for NIBP only, highlight the NIBP Icon and press the ALARMS
SCREEN Menu-Select Key to access the individual parameter Alarm Limits box. The range of Alarm
Limits for the NIBP pressure channels is 5 to 249 mmHg.
4.2.10 Adult vs. Neonatal Mode Operation This monitor allows the operator to determine pressures
on a wide range of patients by allowing the Patient Type to be switched from Adult to Neonate (Adult
Mode is used for Adult and Pediatric patients and Neonate Mode is used for Neonates only). Several
operational parameters (including cuff inflation pressure) are varied depending on the setting of the
PATIENT menu option in the SETUPS Menu. The Adult/Pediatric Mode uses a higher pump
volume and a much larger cuff is used on the patient; in the Neonatal Mode the pump rate is lower and
a much smaller cuff is used on the patient (reference pages xvii, xviii and xix of this manual for cuff
selection and sizes). The Alarm Limits and settings may also change when the patient type is switched
from adult to neo (or neo to adult).
Whenever the NIBP Patient Mode is switched (either from Adult to Neo or Neo to Adult), for
20 seconds the Alarm Tone will sound while the informational display message area indicates
“Change NIBP Cuff.” To change the patient type, press the SETUP control key, scroll to the
PATIENT menu selection and press the Rotary Knob. The “WRONG CUFF” NIBP message
will appear if a reading is initiated and the monitor detects that an incorrect cuff is being used for
the selected patient mode (Adult or Neonate). Replace the patient cuff with the appropriate size
cuff and press the NIBP START/STOP control a second time, this will re-initiate the reading.
4.2.11 Trended Data. For complete information on the trending of patient NIBP data, see Section 5:
Printing and Trending.
WARNING
The patient's blood pressure determinations are not continuous. The blood pressure determinations
are only updated immediately after a blood pressure measurement is taken. When set to the shortest
of the automatic intervals, the constant measurements can cause blood pooling in the limb, and
blood pooling in the limb may artificially increase the value of the blood pressure determinations.
WARNING
The initial cuff inflation pressure will increase to 170 mmHg when changing the patient mode from
Neonate to Adult.

a. The patient sampling circuit (See Figure 4-13) consists of the sampling line and either
a sampling nasal cannula or a side stream adaptor connected to an endotracheal
connector. All fittings in the circuit are Luer-Lock type. All fittings should be fitted
together securely to keep them from separating during the procedure, and to ensure
proper sampling without the introduction of outside air. Loose fitting will result in
Gas measurement errors.
b. Nasal Cannula. The nasal cannula is of the “around-the-ear” type. Place the nasal
prongs gently inside the nose, loop the excess tubing over the patient's ears and then
down under the chin. The cannula may then be fitted by sliding the plastic ring up until
the cannula is secure and comfortable.
c. Endotracheal Adaptor. When using the endotracheal adaptor, attach the Nafion®
Dryer Line before attaching the endotracheal adaptor to the endotracheal tube. Take
great care not to dislodge or move the endotracheal tube when attaching the adaptor.

e. RETURN. Selecting this menu option will return the monitor to the Normal Screen.
4.4.5 Calibration of CO2/N2O Measurement System The monitor will perform automatic Zero
Calibration cycles as part of its normal function. The Zero Calibration cycle is discussed below.
a. Zero Calibration Cycle. A Zero Calibration cycle consists of the realignment of the
Zero point. During this calibration, the monitor makes sure that a concentration of 0%
is measured when room air is flowing through its sample chamber. During a Zero
Calibration cycle the unit performs the following steps:
(1) Switches the input gas valve to the Zero Intake Port placed on the rear panel.
(2) Room air is absorbed through the Zero Intake Port and flushes the pneumatic
system for a few seconds.
(3) Once the channel readings have stabilized, a snapshot is taken and the Zero
point is realigned using these readings as a reference.
(4) The Input Gas Valve is then switched back to the normal position and the gas
being measured is given a few seconds to flush the pneumatic system to clear
out the room air.
4-19
(5) After the readings stabilize, the EtCO2 system begins it’s normal functioning
routine.
b. Automatic Zero Calibration Cycles. An automatic Zero Calibration cycle is
triggered when certain time intervals have passed since the monitor has completed its
warm-up cycle. The timetable for automatic Zero Calibration cycles is the following:
2, 4, 6, 8, 10, 20, 40 and 60 minutes. After the first hour since warm-up, the monitor
will perform a Zero Calibration cycle every hour. In addition, event-related Zero
Calibration cycles are triggered when certain variations are noticed in the input signals
(gases or temperatures). These events are:
(1) A variation of 10% in the concentration of N2O.
(2) A variation in the ambient temperature inside the unit box of 1°C.
(3) A change in the ID of the current anesthetic agent (if Anesthetic Agents feature
is available).
(4) A change in the concentration of the currently measured anesthetic agent by
2% volume (if Anesthetic Agents feature is available).
(5) A variation in the concentration of the currently measured anesthetic agent by
400% relative for concentrations in excess of 1% (if Anesthetic Agents feature
is available).
c. Operator Initiation of Zero Calibration. To manually initiate the Zero Calibration
Routine, perform the following procedure:
(1) Press the SETUP Control Key.
(2) Highlight the SERVICE (BIO-MED) menu option and then press the Rotary
Knob to select.
(3) Highlight the GAS CAL menu option and then press the Rotary Knob to select.
(4) Highlight the ZERO CAL menu option and then press the Rotary Knob to
initiate the Zero Calibration Routine.
This option is identical to the ZERO CAL menu option in the EtCO2 Menu.
4.4.6 Alarm Limits Alarm Limits may be set two ways. To set the Alarm Limits for every available
parameter, from the Normal Screen (with no icons highlighted), press the ALARMS SCREEN Menu-
Select Key. To set the Alarm Limits for EtCO2 only, highlight the EtCO2 Icon and press the
ALARMS SCREEN Menu-Select Key to access the individual parameter Alarm Limits Box. The
range of Alarm Limits for EtCO2 is 5 to 60 mmHg and Off for the Low Limit and 5 to 80 mmHg and
Off for the High Limit.
4.4.7 Trended Data For complete information on the trending of patient EtCO2 data, see Section 5:
Printing and Trending.
4.4.8 EtCO2 Messages The following is a list of messages that may be displayed during EtCO2
monitoring:
NOTE
To perform Zero Calibration, the monitor pulls ambient air through the rear panel CO2 Zero Intake
Port. The Calibration system assumes that the ambient air will contain normal amounts of trace
CO2. If this monitor is placed in an unventilated area that allows CO2 (from the rear panel CO2
Exhaust Port - if not connected to a Gas Scavenging System) to accumulate, the result could be
inaccurate Zeroing of the EtCO2 module and resulting inaccurate patient readings.
CO2 OCCLUSION The air lines have become blocked. Check exposed hose
for kinks and blockages. If blockage appears to be internal
to the unit, contact a Qualified Service Representative.

4.5 Anesthetic Agent/Oxygen Monitoring. (Optional) The Anesthesia Gas Sensor (AGS) is a
non-dispersive, single path Infra-Red spectrometer based upon a high stability IR sensor technology
known as Stabilized Thermopile Bridge (STB). Utilizing the STB technology, the Invivo AGS yields
high output, low noise and ultra stable gas measurements.
The following two secondary menus support the Anesthetic Agent/Oxygen monitoring
feature:
•RECORDER Menu. Used to select recorder functions and to set the recorder and
trace speed.
•ALARMS Menu. Used to set and/or disable the temperature alarms.

other individual factors influencing the behavior of volatile agents are not taken into account.
NOTE
Mixed concentration of Agents are not included in the MAC calculations.
4-24
On the WPU only, if the Agents option is run over a continuous 12 hour period with an O2
concentration of 22% or greater there is a Warning Box that will appear to alert the operator that a
one (1) minute O2 Calibration sequence must be run. The Warning Box will offer the operator a
Yes/No option of running the one (1) minute O2 Calibration sequence, if the operator selects NO,
the message will reappear in 30 minutes. An O2 Calibration message will also appear if the O2
Sensor detects a reading greater than 103% and whenever an O2 sensor is inserted into the back of
the monitor (if the monitor has completed its CO2 zeroing process).
a. Anesthetic Agent Quality Control (QC) Check. Perform a QC Check at least once a
month, or whenever Agent accuracy is questionable.
(1) Before performing the Anesthetic Agent QC Check, the monitor must be at a
stable operating temperature. The monitor must be turned on, with EtCO2 and
Agent parameters active, for a minimum of 45 minutes before the QC check is
performed.
(2) Each QC Check Gas can comes with a nozzle and tubing with a “T” fitting for
connecting to the gas (EtCO2) input port in the monitors front panel.
(3) See the Accessories List in the Table of Contents Section of this manual for
selection of the QC Check Gas for the Anesthetic Agents you are using.
(4) If required, Agent Span Calibration can be performed. Refer to service
instructions for this procedure.
4.5.5 Alarm Limits. The Agent Alarm Limits are set by selecting the GAS ALARMS menu option
in the ALARMS Menu, which is accessed by pressing the ALARMS SCREEN Menu-Select Key, or
by highlighting the AGENT Icon and pressing the ALARMS SCREEN Menu-Select Key to access
the ALARMS Menu.
4.5.6 Trended Data. For complete information on the trending of patient Agent data, see Section 5:

4.5.7 Agent/O2 Messages. The following messages are used for Anesthetic Agent/O2 monitoring:
NOTE
Patient Waste Gas Removal. Continuous exposure of Health Care workers to waste anesthetic
gases (including halogenated agents and nitrous oxide) is not recommended. Always attach the
waste gas connection on the rear of the monitor to the room's gas evacuation system. Avoid venting
any waste anesthetic gas directly into the room air as exposure to waste anesthetic gases above the
recommended OHSA limits could result.
Flashing Insp CO2 Numeric (Fixed CO2 Rebreathing Alarm) The Inspired CO2
numeric turns red and flashes with Alarm sound. Occurs
when Inspired CO2 is greater than 25 mmHg. This
alarm is a fixed, non-adjustable alarm.
Flashing N2O Numeric (Fixed N2O Alarm) N2O numeric turns red and flashes
with Alarm sound. Occurs when N2O is greater than
80%. This alarm is a fixed, non-adjustable alarm.
EtCO2 WARMING UP Message flashing red. Occurs during CO2/Anesthesia
Gas Sensor warmup.
CO2 OCCLUSION Message flashing red with Alarm sound. Occurs when
sample line is occluded.
MULTIPLE AGENTS Message flashes red with Alarm sound. Occurs when
more than one Anesthetic Agent is identified.
4-25
4.5.8 Oxygen Monitoring. This parameter is part of the EtCO2/Agents module. That is, it uses the
exhaust air from the EtCO2/Agents module as its imput and its air flow is controlled by the pneumatic
hardware in the EtCO2/Agents hardware module. The O2 value is displayed in the Anesthetic Agents
Display (See Figure 4-17).
a. Oxygen Module Calibration. The O2 module is calibrated automatically upon
power-up (as described in the NOTE above). Thereafter, is calibrated everytime an O2
CAL is initiated by the user (See the GAS CAL menu (SETUPS/SERVICE(BIO-
MED)/GAS CAL) for further information). The operator is prompted that an O2
calibration is required if O2 remains above 22% for 12 hours and, since O2 calibration
requires one (1) minute, the operator may reject the calibration request by answering
NO to the YES/NO prompt. If NO is selected the operator is then prompted every 30
minutes until the O2 calibration is initiated by a YES response. Calibration is done
based on the assumption that the ambient O2 concentration, sensed at the EtCO2
Zeroing Port, is 20.9% (during calibration, the patient GAS Input Port must not be
connected to an oxygen source).
b. Oxygen Sensor Replacement. The Oxygen Sensor (Invivo Part Number 9445) is
located on the rear of the WPU near the DCU mounting pole. The Oxygen Sensor has
an expected life of greater than six months with expected life inversely proportional to
changes in Oxygen Concentration, Temperature and Pressure. The Oxygen Sensor
begins aging immediately upon the opening of the package and should, therefore, not
be opened until ready for use. The Oxygen Sensor should be replaced periodically as
part of routine maintenance. This monitor cannot be connected to the scavenge gas
system without the Oxygen Sensor installed, never operate without the monitor
connected to the scavenge gas system. Always operate the monitor with the Oxygen
Sensor installed.
(1) Oxygen Sensor Replacement Instructions. Replace the Oxygen Sensor as
follows:
(a) Unplug the adapter cable from the Oxygen Sensor.
(b) Unscrew the Oxygen Sensor by turning it counterclockwise until it
comes free.
(c) Open bag containing new disposable Oxygen Sensor (IRI #9445).
(d) Screw Oxygen Sensor into threaded port on Adaptor Subassembly.
(e) Plug adapter cable assembly into the Oxygen Sensor.
READJUSTING CO2
ZERO
Message flashing red. Occurs during CO2/Anesthesia
Gas Sensor zeroing operation.
REPLACE O2 SENSOR The Oxygen Sensor is bad and must be replaced.
NOTE
When the Agents parameter is turned on the O2 sensor is automatically calibrated during initial
warm up of the EtCO2/Agent Module. During this time the patient GAS input port must not be
connected to an oxygen source as the monitor requires 20.9% Oxygen (room air) for automatic
calibration.

prints patient parameters on the edge of the strip chart and ends with a “snapshot” patient data report.
The Recorder option provides the following features:
• Selection of the traces to be sent to the recorder.
• High frequency response (Single = 800 samples/second at 25 mm/second speed
and Dual = 400 samples/second at 25 mm/second speed) with a bandwidth of 100
Hz.
• Transmitting a calibration waveform to the recorder.
• Total control over the Recorder mode (OFF/AUTO/RUN).
• Selection of patient data report for printing.
• Selection of data collection intervals for report.
• 0 to 16 seconds of trace delay in four increments.
• Selection of 25 or 50 mm/second recorder speed (and screen trace speed).
• The paper record is automatically annotated with the alphanumeric indication of
date, time, trace delay, paper speed, scales, lead configuration, mode, heart rate,
NIBP (which displays systolic, diastolic and mean blood pressures), respiration
rate, EtCO2, SpO2 and Agent Gas ID for expired and inspired breath phases.
• If an active alarm limit is violated, the numeric value of the corresponding
parameter is printed at the beginning of the automatically activated record.
• The recorder uses non-grid thermal paper.
5.1.1 Record Key. The RECORD key starts/stops the Recorder upon operator demand. If left
running the recorder will continue to supply hard copy output for approximately 25 seconds before it
automatically shuts off.
5.2 The RECORDER Menu. The RECORDER Menu provides adjustments that will allow
this monitor to supply concise and up to date printouts suitable to a wide variety of situations. Pressing
the RECORDER SETUP Menu-Select key brings up the RECORDER Menu (See Figure 5-1). If
the recorder is not installed, the message “RECORDER OPTION NOT INSTALLED” is displayed

SECTION 6
ALARMS
6.0 ALARMS.
6.1 Introduction. The 3160 MRI Physiological Monitoring System permits user access to
every parameter alarm with a single select key. Alarm Limits may be turned on, adjusted (manually or
automatically) or turned off in the ALARMS Menu. Individual parameter alarms may also be turned
on and/or adjusted by highlighting the parameter icon and pressing the ALARMS SCREEN Menu-
Select key.
• The 3160 MRI Physiological Monitoring System may be set to give visual alarm
signals only (Alarm Limits set, but Alarm Sound off), or both visual and audible
signals (Alarm Limits set, with Alarm Sound on).
• All settings in the ALARMS Menu, except the Alarm Sound On/Off and Sound
Mode, can be stored and recalled.
6.2 Alarm Limits. The Alarm Limits may be set either manually or automatically. The 3160
MRI Physiological Monitoring System provides access to parameter Alarm Limits through a menu
accessed with the ALARMS SCREEN Menu-Select Key. Alarm Limits may be turned on, adjusted
(manually or automatically) or turned off in the ALARMS Menu.
6.2.1 Default (Pre-Set) Alarm Limits. This monitor will automatically set all the Alarm Limits to
Default settings upon monitor power up. Table 6-1 provides a listing of Factory Default Settings; it is
important to note that Table 6-1 will not represent the Default Values of your monitor if the Default
Values are selected by the User.
6.2.2 Range of High and Low Alarm Limits. Each patient parameter has a LOW and HIGH
Alarm Limit value position as indicated by numerics in the LOW and HIGH columns of Table 6-2.
The Alarm Limits displayed in this menu may be changed manually or automatically using the rotary
knob, after the patient parameter is selected. If a parameter has been turned off from the SETUPS
Menu, then its LOW and HIGH positions will be off on this menu.
6.3 Alarm Setup. Pressing the ALARMS SCREEN Menu-Select Key while in the normal
monitoring mode (Normal Screen displayed) with no icons highlighted will bring up the ALARMS
Menu (See Figure 6-1).
Figure 6-1. The ALARMS Menu
NOTE
The Alarm System automatically prevents the crossover of High and Low Limit settings.
6-2
This menu has the following menu options associated with it:
a. SET INDIVIDUAL. Selecting this menu option allows the operator to adjust
individual Alarm Limits. Once this menu option is selected, turning the knob will
allow the operator to scroll through the individual HIGH and LOW Alarm Limits for
manual modification. Once the limit to be modified is highlighted, pressing the knob
selects the limit and turning the knob changes the value. When the desired setting is
shown in the window, pressing the knob again will make the change effective and
return to scrolling through the individual HIGH and LOW Alarm Limits.
b. CALCULATE ALL. Selecting this menu option causes the monitor to calculate new
alarm limit values on all active parameters at once. The calculations are as described
under UPPER WINDOW and LOWER WINDOW menu options.
c. UPPER WINDOW. Selecting this menu option selects the percent value used in
calculating the HIGH Alarm Limits with the CALCULATE ALL menu option. The
menu options are 5%, 10%, 15%, 20% (default), or 30%. The monitor uses the current
value of the parameter and brackets it with the percentages set by this menu option and
the LOWER WINDOW menu option.
(1) For example, if the patient's heart rate is 60, and both percentages have been set
to 10%, activating CALCULATE ALL menu option will set the LOW Alarm
Limit to 54 and the HIGH to 66 (plus and minus 10 percent of the current heart
rate). Corresponding calculations would be used on each of the other active
patient parameters to set their LOW and HIGH values.
(2) The following exception applies:
• If the value being monitored from the patient is so high or low that
it would exceed the range of 3160 MRI Physiological Monitoring
System Alarm Limits (see below), the LOW or HIGH value is set to
the highest or lowest Alarm Limit for that parameter.
d. LOWER WINDOW. Selecting this menu option selects the percent value that is used
in calculating the LOW Alarm Limits with the CALCULATE ALL menu option. The
menu options are 5%, 10%, 15%, 20% (default), or 30%. The monitor uses the current
value of the parameter and brackets it with the percentages set by this menu option and
the UPPER WINDOW menu option.
(1) For example, if the patient's heart rate is 60, and both percentage have been set
to 10%, activating CALCULATE ALL would set the LOW Alarm Limit to 54
and the HIGH to 66 (plus and minus 10 percent of the current heart rate).
Corresponding calculations would be used on each of the other active patient
parameters to set their LOW and HIGH values.
The following exceptions apply:
• If the value being monitored from the patient is so high or low that
it would exceed the range of 3160 MRI Physiological Monitoring
System Alarm Limits (see below), the LOW or HIGH value is set to
the highest or lowest Alarm Limit for that parameter.
e. ALARM SOUND. Selecting this menu option will turn the alarm sound on/off. When
turned off, an “X” appears in the bell symbol on the screen and the bell symbol in the
menu indicating that the alarm sound has been disabled. This menu option is identical
to, and interactive with, the ALARMS menu option in the SOUND ADJUST Menu.
f. DEFAULT LIMITS. Selecting this menu option causes the monitor to automatically
set the LOW and HIGH Alarm Limits for all parameters at once based on the system
defaults (See Default Limits in Appendix A or Table 6-1 for a listing of the System
Default Values).
6-3
g. TYPE. Selecting this menu option will select whether the audio and visual alarms are
latched or unlatched (see definitions below).
(1) UNLATCHED. The Alarm Tone stops if the violated parameter returns to
within its limits, or the ALARM SILENCE key is pressed.

Figure 6-2. GAS ALARMS (Anesthetic Agents Alarm Limit) Menu
i. GAS ALARMS. Selecting this menu option will bring up the GAS ALARMS
(Anesthetic Agent Alarm Limits) Menu (See Figure 6-2). All the Alarm Limits
associated with the Anesthetic Agent System are adjusted in this menu. The following
is a description of the GAS ALARMS Menu:
This menu has the following menu options associated with it:
(1) SET INDIVIDUAL. Selecting this menu option allows the operator to adjust
individual Anesthetic Agent Alarm Limits. Once this menu option is selected,
turning the knob will allow the operator to scroll through the individual Agent
Alarm Limits for manual modification. Once the limit to be modified is
highlighted, pressing the knob selects the limit and turning the knob changes
the value. When the desired setting is shown in the window, pressing the knob
again will make the change effective and return to scrolling through the
individual Agent Alarm Limits.
(2) CALCULATE AGENT/O2. Selecting this menu option causes the monitor
to calculate new alarm limit values on all active Agent and O2 settings at once.
The calculations are as described under UPPER WINDOW and LOWER
WINDOW menu options.
(3) UPPER WINDOW. Selecting this menu option selects the percent value used
in calculating the HIGH Alarm Limits with the CALCULATE AGENT/O2
menu option. The menu options are 5%, 10%, 15%, 20% (default), or 30%.
The monitor uses the current value of the parameter and brackets it with the
percentages set by this menu option and the LOWER WINDOW menu option.
6-4
(4) LOWER WINDOW. Selecting this menu option selects the percent value that
is used in calculating the LOW Alarm Limits with the CALCULATE
AGENT/O2 menu option. The menu options are 5%, 10%, 15%, 20%
(default), or 30%. The monitor uses the current value of the parameter and
brackets it with the percentages set by this menu option and the UPPER
WINDOW menu option.
(5) ALARM SOUND. Selecting this menu option will turn the alarm sound on/
off. When turned off, an “X” appears in the bell symbol on the screen and the
bell symbol in the menu indicating that the alarm sound has been disabled. This
menu option is identical to, and interactive with, the ALARMS menu option in
the SOUND ADJUST Menu.
(6) DEFAULT LIMITS. Selecting this menu option causes the monitor to
automatically set the LOW and HIGH Alarm Limits for all parameters at once
based on the system defaults (See Default Limits in Appendix A or Table 6-1
for a listing of the System Default Values).
(7) TYPE. Selecting this menu option provides the operator the option to select
whether the audio and visual alarms are latched or unlatched (see definitions
below).
(a) UNLATCHED. The Alarm Tone stops if the violated parameter
returns to within its limits, or the ALARM SILENCE key is pressed.
(b) LATCHED. The Alarm Tone will cease only when the ALARM
SILENCE key is pressed, even if the violating parameter has returned
to within its limits.
(8) RETURN. Selecting this menu option will return the monitor to the Normal
Screen.
j. RETURN. Selecting this menu option will return the monitor to the Normal Screen.
6.3.1 Parameter Alarms Status Screen. While in the Alarms Screen, the Parameter Alarms Status
Screen is displayed to the right of the ALARMS Menu. This screen provides the operator with the
Low and High Alarm Limit Setting along with the Current Measurement value. By using the SET
INDIVIDUAL menu option with the Rotary Knob, the operator may adjust all the available parameter
limit settings.
6.4 Turning Alarms Off on Individual Parameters. Alarms may be set to OFF by pressing
the ALARMS SCREEN menu select key, selecting the SET INDIVIDUAL menu option and then
scrolling to the desired parameter to select it and turn it OFF.
6.5 Alarm Violations. An active Alarm Limit is violated when a patient parameter either
exceeds its HIGH setting or goes below its LOW setting. The alarm system's exact reaction depends on
the settings described in the remainder of this section, but, in general, all alarms operate as follows:
a. The numerics and trace (if displayed) of the violated parameter flash red on the screen.
b. The Alarm Tone on the DCU sounds, if it is enabled.
c. The numerics continue to flash while the parameter violates its Alarm Limit, even after
the Alarm Tone has been silenced by pressing the ALARM SILENCE key.
d. If the Printer is in the AUTO mode, it begins recording. For further information, see
Section 5.
WARNING
Alarm Limits can be set to a wide range including Off. It is the responsibility of the operator of this
monitor to ensure that Alarm Limit values appropriate to each particular patient are established and
set.
6-5
e. The numerics stop flashing after the parameter returns to within its Alarm Limits. If the
alarm system has been set to LATCHED, the numeric continues to flash after the
parameter returns to within its Alarm Limits, until the ALARM SILENCE control
key is pressed.
f. The numerics of the violated parameter flash on the screen and the audible alarm, once
silenced, will not sound again until after the alarm condition has been corrected. Only a
second (different) parameter alarm will cause the alarm sound to reactivate.
6.6 Adjusting the Alarm Tone Volume The Alarm Tone is adjusted in the SOUND ADJUST
Menu, which is accessed by selecting the SOUND ADJUST menu option in the SETUPS Menu.
6.6.1 Disabling the Alarm Tone The Alarm Tone may be disabled permanently in the ALARMS
Menu or it may be disabled temporarily by pressing the ALARM SILENCE control key.
a. The ALARM SILENCE control key has four functions as follows:
(1) WITH UNLATCHED ALARMS. If the alarm system has been set to
UNLATCHED in the ALARMS menu and an Alarm Limit is violated:
• It silences the alarm tone when an active Alarm Limit has been
violated.
WHILE THE PARAMETER CONTINUES TO VIOLATE ITS LIMITS:
• The numeric of the violated parameter will continue to flash on the
screen.
(2) WITH LATCHED ALARMS. If the alarm system has been set to
LATCHED in the ALARMS menu and an alarm is violated:
WHILE THE PARAMETER CONTINUES TO VIOLATE ITS LIMITS:
• It will silence the Alarm Tone.
• The numeric will continue to flash, even after the parameter returns
to within its Alarm Limits.
WHEN THE PARAMETER GOES BACK WITHIN LIMITS:
• It will silence the Alarm Tone, stops the numeric from flashing and
puts the Alarm System into the Alarm Hold mode.
WHEN THE ALARM HAS BEEN SILENCED AND THE PARAMETER
RETURNS TO WITHIN LIMITS:
• Pressing ALARM SILENCE will stop the numeric from flashing
and puts the Alarm System into the Alarm Hold mode.
NOTE
The Alarm Tone only applies to the DCU, there is no speaker on the WPU.
WARNING
Once an alarm condition has been silenced it will not sound again for any reason as long as that
alarm condition continues. For example, if a patients Heart Rate drops below the set limit and that
alarm is silenced, the alarm will never sound that condition again unless the Heart Rate returns to
within limits and then drops below the limit again.
6-6
(3) ALARM SILENCE. When the monitor goes into Alarm, pressing the
ALARM SILENCE control key silences the Alarm Tone for the current alarm
only. While the monitor is in the Silence mode, the letter “S” is displayed
within the Alarm Status Symbol (Alarm “Bell”), the Alarm Bell flashes and the
text “Alarm Silenced” is displayed in the middle of the display screen. If any of
the silenced alarm conditions return to acceptable limits, the monitor will
respond according to the above described Latched and or Unlatched operation.
If a new alarm occurs after the Silence mode is entered, the monitor will sound
the Alarm Tone for the new alarm. Pressing the ALARM SILENCE control
key a second time (after entering the Silence mode) will place the monitor into
the Alarm Hold state.
(4) Alarm Hold “SOUND ON HOLD” Mode. The Alarm Tone must be turned
on (no “X” in the bell shaped Alarm Status Symbol) to enter SOUND ON
HOLD. The Sound on Hold feature is used to temporarily disable the Alarm
Tone. This might be useful, for example, when changing ECG leads, when
drawing blood from an arterial pressure line or for any user activity which
might cause an unwarranted alarm.
WHEN NO ALARM CONDITION EXISTS:
• Pressing the ALARM SILENCE key will activate Sound on Hold
(a “SOUND ON HOLD” message appears in the middle of the
screen and an “H” appears in the Alarm Status Symbol). Just under
the message there is a count down timer starting at 180 (counting
down at a 1 second rate) giving the time left before the Alarm Tone
is reactivated.
WHEN AN ALARM CONDITION EXISTS:
• If the Alarm Tone is sounding, the first press of the ALARM
SILENCE key stops the Alarm Tone, and a second press enables
Sound on Hold.
AUTOMATIC EXIT FROM ALARM HOLD:
• The monitor will automatically exit alarm hold after 180 seconds,
and the “SOUND ON HOLD” message will disappear from the
screen.
MANUAL EXIT FROM ALARM HOLD:
• To exit from Sound on Hold before 180 seconds, press the
ALARM SILENCE key (which will remove the “SOUND ON
HOLD” message from the screen).
6.7 Standby Mode. Pressing the STANDBY Control Key will place the monitor into the
Standby Mode. While in the Standby Mode the monitor will continue to track and update the active
patient parameters but three key features will be disabled: 1) All audible alarms are disabled; the fact
that the alarms are disabled is indicated on the Display Screen by an X through the bell shaped Alarms
Status Symbol; it is also important to note that the Parameter Waveform and/or Numeric Display
continue to operate normally and will turn Red if any active parameter violates its Alarm Limits, 2)
automatic NIBP Measurements are suspended (if active, the current measurement will abort), and 3)
No Automatic Printout is generated. When NIBP measurements are resumed, the intital reading will be
taken at the default inflation pressure that is used for all initial NIBP measurements.

REPAIR
All repairs on products under warranty must be performed by Invivo personnel, or an authorized
Invivo Service and Repair Center. Unauthorized repairs will void the warranty.
If a monitor fails to function properly or requires maintenance, contact Invivo Technical Service
at 1-800-331-3220 during normal business hours EST or 24 hour emergency technical assistance.
Invivo Technical Service will advise you of the corrective action required. If you are advised to
return the monitor to Invivo for repair, please do the following:
1 Obtain a Return Authorization Number. This will ensure proper routing and facilitate
timely repair of your monitor.
2 Remove batteries and package the monitor with adequate protection. If available, use the
original carton and packing materials in which the monitor was shipped from Invivo.
3 Include a brief description of the problem as well as the name, address and phone number of
the person to be contacted for additional information.
4 Include a purchase order with the monitor being returned if it is out of warranty; Invivo
Technical Services can advise you of your monitor's warranty status, if need be. Repairs will be
made at Invivo's current list price for the replacement part(s) plus a reasonable labor charge.
5 Ship the monitor, transportation prepaid, to the location specified by your Invivo Technical
Service Representative with the Return Authorization Number written on the outside of the
shipping carton. Repairs will be made, normally, within two weeks, and the monitor will be
returned to you prepaid.
