Overview
The 90478-A digital telemetry receiver module, when used in conjunction with
Spacelabs Medical telemetry transmitters, an Ultraview or PCMS™ monitor, and
90479-A modular receiver housing, provides continuous monitoring of
electrocardiographic signals in order to detect abnormal cardiac rhythms,
including asystole, ventricular fibrillation, and ventricular tachycardia. In addition,
when used with the 91343 digital telemetry multi-parameter transmitter and the
90217 Ambulatory Blood Pressure (ABP) monitor, monitoring of
electrocardiographic signals is augmented by the availability of continuous or
episodic SpO2 measurements and episodic noninvasive blood pressure (NIBP)
measurements.

Intended Use
As an option, on adult patients, additional abnormal cardiac rhythms, such as
ventricular runs, tachycardia, and ST segment deviations can be detected. The
Ultraview Digital Telemetry System also provides a means for the episodic
monitoring of NIBP signals to detect abnormal events such as high and low blood
!• Spacelabs Medical’s telemetry equipment complies with Part 15
and Part 95 of the FCC Rules and with RSS-210 of Industry
Canada and with requirements of other national spectrum
management authorities. Repeated here are operational
cautions for biomedical telemetry from the FCC Rules
(47CFR15.242(f)):
“Biomedical telemetry devices must not cause harmful
interference to licensed TV broadcast stations or to other
authorized radio services, such as operations on the
broadcast frequencies under subpart G and H of part 74 of
this chapter, land mobile stations operating under part 90 of
this chapter in the 470-512 MHz band, and radio astronomy
operation in the 608-614 MHz band. (See section 15.5). If
harmful interference occurs, the interference must either be
corrected or the device must immediately cease operation
on the occupied frequency. Further, the operator of the
biomedical telemetry device must accept whatever level of
intereference is received from other radio operations. The
operator (health care facility) is responsible for resolving
any interference that occurs subsequent to the installation
of these devices.”
• Medical telemetry equipment is only for installation and use in
hospitals and health care facilities. It is not permitted for use in
vehicles that operate outside of the medical facility premises.
The user of this equipment is not authorized to make any
changes or alterations that could compromise the national
certifications.
• Operation of telemetry equipment in the 608 - 614 MHz, 1395 -
1400 MHz, 1427 - 1429.5 MHz, and 1429.5 - 1432 MHz parts of
the Wireless Medical Telemetry Service (WMTS) and in
authorized spectrum of each country, may be geographically
restricted by government regulation. Spacelabs Medical
Customer Service can assist in evaluating if a hospital’s location
requires coordination with a protected radio astronomy
observatory or other protected government site that may be
within an 80-km (54-mile) radius.
WARNING:
• Changes or modifications not expressly approved by
Spacelabs Medical will void the user’s authority to operate
the equipment.

pressure. Finally, it provides a means for both continuous and episodic monitoring
of pulse blood oxygen saturation signals in order to detect oxygen desaturation
caused by abnormal pulmonary/circulatory functions.
The Spacelabs Medical 91341, 91343, and 91347 Ultraview Digital Telemetry
Systems are intended for use with either adult or neonatal patients in a hospital
environment. When the NIBP option is selected in the 91343 configuration, the
NIBP feature is to be used with adult patients only.
Transmitters
The transmitter is a small, battery-powered device carried by the patient that
monitors ECG activity and SpO2/NIBP (91343 only) data, and transmits this
information to the telemetry receiver module.
• The 91341 transmits two leads of ECG and use up to five lead wires. One or
two leads may be displayed.
• The 91343 and 91347 transmit four leads of ECG and use up to five lead
wires. However, only two leads may be displayed simultaneously.
• The 91343 is also capable of transmitting numerical NIBP and SpO2 data.
This data is displayed simultaneously with that of the ECG waveform data.
Each telemetry channel requires its own transmitter operating on a unique radio
frequency. Channel receivers are tuned from the Ultraview monitor touchscreen to
receive the available transmitter frequencies.
!• Episodic monitoring of NIBP values and continuous and
episodic monitoring of blood oxygen saturation values are only
supported in conjunction with ECG monitoring. SpO2 and NIBP
alarms are inhibited by ECG leads-off condition.
WARNING:
• The Ultraview Digital Telemetry transmitters are
contraindicated for use with other medical instrumentation
(e.g., respiration monitors using impedance
pneumography, electrocautery, etc.) that source electrical
current through the patient. Further, telemetry monitoring
is contraindicated for the Operating Room environment.
!• Operation of this equipment may be subject to licensing
requirements by your local telecommunications authority.
Please check with your Spacelabs Medical customer service
representative.

connected to the patient. The ECG lead wires are attached to these electrodes
and connected to the transmitter. Lead wires that are poorly connected to the
patient (including compromised electrode connections) are locally detected and
identified with flashing indicators at the ECG patient input connector. A patient-
operated RECORD button initiates an ECG strip at the system printer, if this
feature is enabled at the central or bedside monitor.
WARNING:
• Medical telemetry spectrum allocations may be assigned to
frequencies already allotted to other priority users. This
means that telemetry operations may be exposed to radio
frequency interference that may disrupt or impede
telemetry patient monitoring during the life of this
equipment. You are urged to regularly consult with
applicable local and federal regulatory agencies (e.g., FCC,
FDA, etc.) regarding the locations and frequencies of other
spectrum users in your geographic area. Spacelabs
Medical service representatives may be able to assist you
in reconfiguring your equipment frequencies to reduce the
risk of interference. Spacelabs Medical cannot, and does
not, guarantee interference-free telemetry operation.
CAUTION:
• This device has a limited bandwidth range of .05 to 30 Hz,
which may adversely affect the recording of high
frequency components in the ECG signal, especially when
the morphology of the ECG changes rapidly.
• This device has a limited dynamic range of ±4 mV, which
may render the device vulnerable to saturation by ECG
signals with amplitudes higher than 4 mV.
• To clean the transmitter, use only the following solutions
per the manufacturer’s labeling: isopropyl alcohol (70%),
hydrogen peroxide, Cidex, Betadine, and Clorox. Use of
cleaning solutions other than those listed will VOID the
warranty of the digital telemetry transmitter cases.
• Patients should not use any type of electronic equipment
(e.g., portable radios, cellular telephones, pagers, personal
computers, etc.) while connected to any medical electronic
device without in-situ evaluation by the biomedical
engineering staff.
• Use of 2-way radio equipment and other personal
communication devices must be evaluated in-situ to
assess the potential for disruption of monitoring.
!• Clean the transmitter after each use. The transmitter does not
require any preventive maintenance other than cleaning.

Transmitter Batteries
A 9-volt alkaline battery is recommended for standard use in the digital telemetry
transmitter. A 9-volt lithium battery may also be used for applications requiring
more extended battery service life.
Always observe the battery position and polarity as illustrated at the bottom of the
battery compartment. After battery installation, close and latch the compartment
cover. The transmitter begins transmitting as soon as the battery is in place.
Battery Disposal
Both the 91341, 91343, and 91347 Ultraview Digital Telemetry transmitters are
operated by 9-volt primary (non-rechargeable) batteries that must be properly
disposed when discharged. The batteries specified may be of either alkaline or
lithium chemistry. Attempting to recharge these batteries is not recommended and
can result in leaking, venting, or explosion.
Follow the battery manufacturer’s recommended handling procedure for both
types of batteries: Collect and transport the batteries in a manner that prevents
short circuit, compacting, mutilation, or any other physical abuse or electric
handling that would destroy their physical integrity. Exposure to high temperatures
or fire can cause the batteries to leak, vent, or explode.
Disposing of used batteries may be subject to national, state/provincial, and/or
local regulation, which varies depending on jurisdiction.
The recommended disposal procedure for alkaline batteries is to transport them to
a hazardous waste landfill. Since these batteries may not be classified as
hazardous waste, they may be transported to the disposal facility as non-
hazardous waste.
The recommended disposal procedure for lithium batteries is to transport them as
hazardous waste to a hazardous waste facility. If the batteries are physically
sound, disposal of these discharged batteries in a hazardous waste landfill may
be permissible. If the batteries are leaking, cracked, opened, vented, or otherwise
not physically sound, they must be transported to a qualified hazardous waste
facility.
!• Whenever the transmitter is not in use, the battery should be
removed. Insert a battery only when the transmitter is being
used with a patient.
• The LOW BATTERY message appears and an alarm tone
sounds (if LO BAT is set to ON) when the transmitter battery
voltage falls below approximately 7.0 volts. When this message
appears, the transmitter has approximately three hours of
operating time left, depending on transmitter type, selected
options, and the type of battery.
• When the battery level falls below approximately 7.0 volts, the
low battery LED on the transmitter will flash once every 15
seconds. When the battery level falls below 6.0 volts, the low
battery LED will flash once every two seconds. When the
battery level falls below 5.5 volts, the SpO2 and NIBP functions
will shut down. The LOW BATTERY message may appear after
the low battery LED on the transmitter begins to flash.

Digital Telemetry Receiver Module
The 90478 telemetry receiver module plugs into a bedside, central, or transport
monitor, or into a digital telemetry module housing. The receiver module receives
patient vital signs data from the transmitter. This data is reconstructed by the
receiver module, displayed on the monitor and analyzed as described in the ECG,
Arrhythmia, and ST Analysis chapters of the UCN Operations Manual, and in the
SpO2 and NIBP sections in this chapter.
Digital Telemetry Receiver Housing
The telemetry receiver housing can hold up to eight separate telemetry receiver
modules. Except for the ON/OFF switches, there are no operator controls on the
module housing. For normal operation with AC mains power applied, the AC
mains indicator light on the front panel of the housing must be illuminated.
Operating the system without AC mains power is limited to ten minutes of battery
backup time.
WARNING:
• Telemetry systems may be more susceptible to
interference than hardwired systems, which may impact
signal quality.
• Operation of hand-held, wireless telephone equipment
(e.g., cordless telephones, cellular telephones) near
telemetry systems may cause interference and should be
discouraged. While personal communication devices are
turned on, a separation of > 6.5 feet (> 2 meters) should be
maintained between personal communication devices and
interior walls, the patient cables, and any electronic
medical device to which the patient may be connected.
Patients should not use any type of electronic
communication equipment while connected to any
electronic medical device without an on-site evaluation by
the biomedical staff. Two-way radio equipment and other
personal communication devices must be evaluated on
site to determine if additional space limitations are needed.
• Do not install a telemetry receiver module into a bedside
that is currently equipped with any other ECG module,
hardwired or telemetry (or SpO2 module or NIBP module, if
the 91343 is operating with that specific receiver module).
Doing so may cause inaccurate patient data displays at
remote monitors.

Cleaning
Clean the transmitter after each use. The transmitter does not require any
preventive maintenance other than cleaning.
To clean the transmitter, use only the following agents.
• Mild soap and water solution
• U.S. Pharmacopoeia (USP) green soap
• Sodium hypochlorite solution (1:10 dilution of household bleach in water)
• Phenolic germicidal detergent solutions (1% aqueous solutions)
• Isopropyl alcohol solution (70%)
Assigning a Telemetry Channel
Telemetry transmitters have preassigned channel frequencies. This channel
number is identified on the back of the case and cannot be changed. To receive
this telemetry channel, one of the receivers in the telemetry receiver housing must
be tuned to its assigned frequency.
Tuning a Receiver for a Bedside
The central monitor must be tuned by a qualified service person, but the bedside
monitor may be tuned using the ECG TM SETUP menu. You may use this menu
to tune the receiver module to the pre-assigned channel frequencies on the
telemetry transmitter.
!• Tuning telemetry receiver modules to transmitter channels at
the central monitor must be done by a qualified service person.
• Your central monitor can be configured to remember beds that
are assigned to individual telemetry channels using the Module
Configuration Manager feature. These beds are permanently
assigned until you unassign or reassign them. Refer to the
Module Configuration Manager chapter of the UCN Operations
Manual.
!• The module default is set for North America using UHF band
operation. For alternate band operation, or if operating in
another country, you must select the appropriate frequency
band using the Module Configuration Manager.

Acknowledging Signal Loss
When a telemetry signal is lost because the transmitter is out of range or the
battery is removed, the receiver initiates a squelch condition indicated by a
triangular waveform that replaces the normal ECG waveform and SQUELCH is
included in the edge print for any strip chart recording. The ECG trace
automatically begins again if the lost signal returns.
After eight seconds of signal loss, the IS SIGNAL LOSS PERMANENT? message
appears. Selecting NO suspends alarm tones. Selecting YES displays the
message DISCHARGE THE PATIENT? Selecting YES again, provides you with
the message PURGES DATA-ARE YOU SURE? Selecting YES a third time,
discharges the patient from the system and purges all data for that patient.
Selecting NO at any point in this sequence returns you to the previous option.
Setting Battery Status Alarms
The telemetry battery alarm tone, and a LOW BATTERY message in the ECG
zone involved, alerts you to a low battery condition in the transmitter. You may
disable the low battery alarm tone, if your bedside or central is configured to
do so.
The factory default setting for low battery alarm is ON.
Controlling Patient-Initiated Recordings
If the Patient Record function is activated (PT RECORD is YES) in the ECG TM
SETUP menu, the patient may initiate a recording by pressing the RECORD
button on the front of the transmitter.
Telemetry Alarm Message Summary
INTERMITTENT SIGNAL LOSS
The intermittent signal loss message indicates that the patient may be out of
antenna range, or the battery is depleted. Return the patient into antenna range.

Overview
Digital telemetry ECG monitoring provides continuous monitoring of
electrocardiographic signals in order to detect abnormal cardiac rhythms,
including life-threatening arrhythmias such as asystole, ventricular fibrillation, and
ventricular tachycardia.
Setting Up ECG Monitoring
To set up ECG monitoring, plug each lead wire into the transmitter, connect each
to an electrode, and then attach the leads to the patient. Match the lead wire color
to the color-coded connectors on the top of the transmitter case. Refer to the ECG
chapter in this manual for details regarding electrode application. Telemetry
patients are commonly ambulatory and require optimal skin preparation and lead
application to minimize motion artifact. After the electrodes and lead wires have
been attached, it is important to tape a loop of lead wire close to the electrode to
minimize stress or pulling on the electrode itself. This is called stress-looping.
ECG monitoring begins when the telemetry receiver module detects a signal sent
by a telemetry transmitter. The telemetry transmitter sends a signal as soon as its
battery is installed.
ECG telemetry reception requires the following minimum conditions:
• The telemetry receiver module must be connected to an Ultraview or PCMS
monitor, either directly or through a module housing, with the power ON and a
Spacelabs Medical diversity antenna connected.
• ECG electrodes must be properly attached to the patient; and lead wires
must be properly attached to the transmitter.
• The transmitter battery must be functional.
• The telemetry receiver module must be tuned to the telemetry transmitter's
frequency (channel number).
To initiate ECG monitoring:
1Select a transmitter
2Note its channel number
3Attach lead wires to transmitter
4Attach lead wires to electrodes
5Apply electrodes to patient
6Install a transmitter battery
7Close the transmitter case

ECG monitoring in telemetry is identical to hardwired ECG monitoring. Refer to
the ECG, Arrhythmia, and ST Analysis chapters of the UCN Operations Manual
for detailed descriptions of configurations, displays, and controls. A brief overview
of ECG monitoring follows.
Electrodes
For ECG tracing with telemetry, use silver/silver-chloride electrodes or their
equivalent. Always connect all the electrodes required for a particular lead.
Missing electrodes may result in the loss of ECG tracing. Refer to the ECG
chapter in the UCN Operations Manual for information on placing the electrodes.
!• All system connections must be made by Spacelabs Medical
personnel only.
• Leakage currents are not affected by the high level output.
The patient is electrically isolated from the patient monitor by
the RF link.
WARNING:
• Operating television receivers or other CRT displays near
the transmitter (within 2 to 3 feet), or operation of some
pacemaker programmers may suppress the ECG
waveform, preventing QRS detection and rate counting. An
erroneous asystole alarm may result.
• Signals resulting from devices such as Automatic
Implantable Cardiac Defibrillators (AICD) may momentarily
blank the ECG trace rather than display an out-of-range
signal. In such cases, it may not be apparent that the AICD
has signaled and the condition of the patient should be
checked. In all instances of AICD signaling, the bedside or
central will redisplay the ECG waveform within 5 seconds.
WARNING:
• Use only Spacelabs Medical recommended electrodes.
Some electrodes may be subject to large offset potentials
due to polarization. Recovery time after application of
defibrillator pulses may be especially compromised.
Squeeze bulb electrodes, commonly used for diagnostic
ECG recording, may be particularly vulnerable to this
effect.
ECG
071-0774-00 Rev. A 2-3
CAUTION:
• Visually inspect each lead wire for obvious damage and
replace them as needed.
• Only use patient cables and lead wires specified by
Spacelabs Medical. Other cables and lead wires may
degrade performance and may damage the monitor during
defibrillation. Non-Spacelabs Medical cables and lead
wires may also change the required input impedance and
DC offset voltage, affecting monitor performance.
• Do not use stainless steel electrodes.
• Do not allow conductive parts of electrodes and
connectors, including the reference electrode, to contact
other conductive parts, including the ground.
• Poor cable dressing or improper electrode preparation
may cause line isolation monitor transients to resemble
actual cardiac waveforms and inhibit heart rate alarms.
Refer to the ECG chapter of the UCN Operations Manual for
details on proper electrode preparation and application.

Monitoring Paced ECG Patients
When monitoring pacemaker patients, use the paced feature to automatically
enhance pacemaker spikes for display and eliminate them from the heart rate
counter. The last YES/NO setting of the paced feature you select is retained as
the default.
If the interval between the pacemaker pulse and the QRS complex is greater than
150 milliseconds, the beat is considered to have originated in the atria and is not
classified as a paced beat.
To prevent pacemaker pulses from being counted as actual beats, specialized
circuitry removes the pacemaker pulses from the ECG signal and replaces them
with pacemaker flags.
!• The optimal leads for monitoring paced patients may vary. In
telemetry monitoring, pacemaker spikes are detected on lead II.
If pacemaker spikes are not detected, change the electrode
position.

Restoring Default Settings
With the Module Configuration Manager feature, you can restore all default
settings. User-configurable options are listed in the Module Configuration
Manager chapter of the UCN Operations Manual.
Changing the Display Resolution
The MONITOR/EXTENDED key determines the display resolution of the two ECG
traces, whether or not both traces are currently displayed on the monitor.
Table 1: Display Resolution
The factory default setting for display resolution is monitor mode.
WARNING:
• ECG detection circuitry may continue to count the
pacemaker rate during occurrences of cardiac arrest or
some arrhythmias. Do not rely entirely upon ECG rate
alarms. Keep pacemaker patients under close surveillance.
• The system may insert pacemaker flags into the ECG
signal in response to signals that are not pacemaker
pulses. Therefore, if you use a Spacelabs Medical monitor
to observe pacemaker performance, you must take into
account all possible sources of pacemaker flags.
• Use the pacemaker manufacturer's performance analyzer
as the primary means of evaluating pacemaker operation.
!• RESTORE SETTINGS changes the user-configurable options
for all parameters in the module.

Overview
Pulse oximetry enables you to noninvasively monitor a patient's hemoglobin
oxygen saturation either continuously or episodically. The oximetry sensor
contains two light emitting diodes (LEDs) that transmit specific wavelengths
(approximately 660 and 940 nanometers) of light that are received by a
photodetector.
Oxygen saturated blood absorbs light differently than unsaturated blood. Thus,
the amount of light absorbed by the blood can be used to calculate the ratio of
oxygenated hemoglobin to total hemoglobin in arterial blood. This ratio is
displayed as percent SpO2. Normal values range from 95 to 100%.
WARNING:
• A pulse oximeter should NOT be used as an apnea monitor.
• A pulse oximeter should be considered an early warning
device. If a trend towards patient deoxygenation is
indicated, blood samples should be analyzed by a
laboratory co-oximeter.
!• With the Module Configuration Manager feature, you can define
your own default settings for characteristics such as alarm
limits, alarm priority, and display configuration. Refer to the
Module Configuration Manager chapter in the UCN Operations
Manual for further details.
• Blood oxygen saturation monitoring must be performed in
conjunction with ECG monitoring. The ECG lead wires of the
91343 must be connected to the patient in order to perform
ECG and blood oxygen saturation monitoring.

Setting Up SpO2 Monitoring
The 91343 digital telemetry multi-parameter transmitter uses Spacelabs Medical
sensors as well as those from other manufacturers. Refer to Accessories on page
1-12 for information concerning specific sensors.
All sensors require an adapter cable between the sensor and the transmitter.
Because the adaptor cable is reusable, do not discard it when you have finished
using a disposable oximetry sensor. Disconnect the sensor cable from the adapter
cable before discarding the sensor.
To connect the SpO2 adapter cable to the transmitter, align the cable with the
notch on the front of the transmitter connector, and push the cable straight down
into the transmitter. To remove the cable, press the latch release on the bottom of
the cable, and pull the cable straight out.
Figure 3-1: SpO2 Adapter Cable to Transmitter
To enable SpO2 monitoring in the 91343 digital telemetry multi-parameter
transmitter, choose an averaging interval of 4, 8, or 16, seconds by setting DIP
switches 1 and 2 as explained in Setting SpO2 Data Averaging Period and
Sampling Interval on page 3-6.
CAUTION:
• Use only patient sensors specified by Spacelabs Medical.
Using sensors other than those specified may degrade
performance and damage the transmitter during
defibrillation.
• Check the sensor site frequently. Do not allow the sensor
to remain on one site for a prolonged time, especially when
monitoring neonates. Refer to the sensor manufacturer's
instructions.
• Never attach an SpO2 sensor on a limb being monitored
with a blood pressure cuff or a limb with restricted blood
flow.
• A poorly applied sensor may give inaccurate saturation
values.
• Choose a site with sufficient perfusion to ensure accurate
oximetry values.
CAUTION:
• Never twist the cable.
To set up SpO2 monitoring:
1Open the battery cover and
remove the battery
2Confirm that the DIP switches 1
through 8 are in the correct
setting (Switch 7 must be set to
ON for neonatal use and to OFF
for adult use)
3Reinstall the battery and close
the battery cover
4Connect the SpO2 adapter
cable (P/N 700-0014-00) to the
transmitter
5Attach the sensor to the patient

Ensuring Accurate Monitoring
Each sensor requires site specific application procedures, and the following
general points will aid oximetry monitoring success.
• Choose a site that provides proper alignment of the LEDs and receiving
photodetector.
• Reduce light interference when monitoring under bright light by using a light
block over the sensor.
• Select a site that has unrestricted blood flow and can remain as immobile as
possible to reduce or eliminate movement artifact.
• Do not restrict blood flow when securing a sensor with tape.
• Do not select a site near potential electrical interference (e.g., electrical
cords).
• The SensorWatch bar should be above the minimum signal level.

Setting or Adjusting Alarm Limits
Pulse oximetry alarm limits and delays are based either on factory default limits or
user-defined limits. The factory default settings for alarm limits are 100% for high
and 85% for low. For alarm delays, the factory default settings are 15 seconds for
alarm limit delay and 20 seconds for message alarm delay. Refer to the Alarms
chapter in the UCN Operations Manual for details concerning UCN alarm
operation.
When SpO2 alarms are enabled, a bell symbol will be displayed between the
“SpO2” label and the SpO2 measured saturation value. When any SpO2 alarm is
detected, the displayed parameter value (item 1 in Figure 3-2 and Figure 3-3 on
page 3-3) will blink yellow if the alarm priority is Low or Medium, and will blink red
if the alarm priority is High. This is done independently of any other ECG or NIBP
alarm indications.
When SpO2 alarms are enabled and the SpO2 high limit is exceeded, the SpO2
High=XXX key will blink in the color of the highest priority alarm present. When the
SpO2 low limit is exceeded, the SpO2 Low=XXX key will blink in the color of the
highest priority alarm present. Refer to Directory of Keys - UCW and Ultraview
1700 on page 1-1.
Refer to the Module Configuration Manager chapter of the UCN Operations
Manual for SpO2 parameter tables that list available user settings and factory
defaults for this parameter.

Setting SpO2 Data Averaging Period and
Sampling Interval
SpO2 data averaging is used to smooth the oximetry saturation value by
averaging the patient input values over 4, 8, or 16 seconds. This selection is made
by setting the DIP switches 1 and 2 beneath the battery compartment in the 91343
digital telemetry multi-parameter transmitter. The default value is 8 seconds.
Refer to Figure 3-4 on page 3-6.
Table 1: DIP Switch 1 and 2 Settings
The current setting of the SpO2 averaging period may be displayed by pressing
the ECG CHANNEL FORMAT key and enabling SpO2.
Figure 3-4: DIP Switch Setting in Battery Compartment
The sampling interval selection enables you to determine how often an SpO2
measurement will be taken. Less frequent SpO2 readings can extend the usable
life of the battery. (Refer to the Ultraview Digital Telemetry Products data sheet,
!• Setting both DIP switches 1 and 2 to ON disables SpO2 data
transmission.
• To enable SpO2, remove the battery, set the selected interval,
and re-install the battery.
• Disabling SpO2 operation in the 91343 transmitter lengthens
battery life.
CAUTION:
• Use care when configuring the DIP switches. Avoid using
pens or pencils to configure the DIP switches since they
may cause contamination. Avoid using sharp cutting
instruments which may cause physical damage.

made by setting DIP switches 3 and 4 beneath the battery compartment. The
default setting is in continuous.
Table 2: DIP Switch 3 and 4 Settings
Viewing Pulse Rate
In normal operations, the heart rate for display is obtained directly from the
acquired ECG leads or an alternate rate source. SpO2 can be used as the
alternate source, if it is set for continuous measurement. When it is set for
episodic measurement, SpO2 cannot be used as an alternate rate source.
SpO2 with Intra-Aortic Balloon Pumps
Enabling the intra-aortic balloon pump (IABP) feature informs the SpO2 software
that an IABP is in use. The 91343 must differentiate between true arterial
pulsations and those produced by the IABP. With the IABP feature enabled, the
transmitter excludes the IABP-generated pulsations from the calculation for SpO2.
The IABP feature also may be useful with patients experiencing irregular heart
rhythms. Enabling the IABP feature permits the transmitter to reject irregular
pulses, providing a more accurate SpO2 measurement.
CAUTION:
•No SpO
2 monitoring occurs between episodic sampling
intervals. Clinical practice or medical judgement should be
used in selecting continuous or episodic SpO2 monitoring
mode for each specific patient.
DIP Switch 3 DIP Switch 4 Effect
OFF OFF Continuous sampling (default)
OFF ON 2 minute sampling interval
ON OFF 5 minute sampling interval

CAUTION:
• DIP switch 8 must remain OFF for normal operation.
!• When the IABP feature is enabled, the pulse rate obtained from
SpO2 may not match the heart rate obtained from ECG.
• In cases of excessive patient motion or artifact, the accuracy of
the SpO2 measurement may be compromised when the IABP
feature is enabled.
• When the IABP operation is selected, the SpO2 status key in
the Channel Format menu indicates IABP.

Overview
The 91343 digital telemetry multi-parameter transmitter sends NIBP patient data,
acquired by the 90217 ambulatory blood pressure (ABP) monitor, to the 90478
digital telemetry receiver. The 90478 displays the patient’s episodic NIBP data
and trigger alarms based on thresholds set at the patient monitor.
The 90217 ABP monitor is a small, lightweight, battery-powered unit designed to
take blood pressure measurements. Refer to the 90217 Operations Manual
(070-0137-xx) for more detailed information on this product, its initialization by a
direct PC interface (90121 ABP Report Management System Operations Manual
070-0529-xx), Patient Preparation, and Event Codes.
NIBP uses oscillometric monitoring to measure systolic (S), diastolic (D), and
mean (M) arterial blood pressures. The pressure readings are sent from the
90217 ABP monitor to the 91343 transmitter by a connecting cable. The 91343
transmitter then includes the NIBP readings in the communications to the 90478
receiver using the radio frequency data link. Received NIBP measurements are
checked to eliminate the possibility of erroneous readings and valid
measurements are displayed on the patient monitor and stored in the patient
monitor for trending. The Ultraview monitor displays valid measurements and the
time the measurement was acquired. The most recent reading is displayed by the
Ultraview monitor. The most recent 120 readings are stored and may be displayed
by the monitor.

Setting Up NIBP Monitoring
Proper cuff selection and application is critical in ensuring the accuracy of NIBP
readings. To ensure proper cuff selection, first measure the circumference of the
limb at its midpoint. Match the limb measurement to the range of appropriate
circumferences (in centimeters) specified on each cuff. If the cuff bladder is too
wide for the patient, the reading will be falsely lowered; if it is too narrow, the
reading will be falsely elevated. Undersizing the cuff results in the greatest chance
of error, so a variety of cuff sizes should be available to accommodate your full
patient population.
Apply the cuff snugly. When the cuff is properly applied to an adult, you should be
able to insert one finger between the cuff and the arm. If you can insert two
fingers, the cuff is too loose, which may result in falsely elevated readings. Ensure
that the hose is not kinked when the cuff is applied.
During blood pressure measurement, the inflated cuff reduces blood flow to the
limb to which it is applied. Do not apply a cuff to a limb that has restricted blood
flow. Check the patient periodically.
!• The 90217 ABP Monitor is intended for use with adult patients
only and, when used with the 91343 Digital Telemetry System,
must also involve ECG monitoring.
• The ECG lead wires of the 91343 must be connected to the
patient in order to perform ECG and NIBP monitoring.
• The 90217 ABP, when used with the 91343 Digital Telemetry
system, purges its measurements as they are successfully sent.
This operation differs from when the 90217 ABP is used in a
stand-alone manner and stores a maximum of 240 NIBP
readings and event codes.
• NIBP readings which are not successfully transmitted by the
90217 to the 90478 within twenty-four hours of their
measurement are unavailable for patient monitor display or
trending.
!• Do not apply a blood pressure cuff to a limb being monitored
with a pulse oximetry sensor, because SpO2 is affected during
NIBP readings. Avoid applying a cuff to a limb that has an
intravenous line in place. Do not apply a cuff to a limb that has
restricted blood flow.
• Use only single hose cuffs to ensure proper operation.
Spacelabs Medical’s hoses are non-conductive with respect to
defibrillator discharge effects.
To set up NIBP monitoring:
1Configure 91343 DIP switch 5
to ON (refer to Figure 4-4 on
page 4-7)

Patient Factors Affecting Readings
Excess patient movement, speech, or muscle contractions as a result of severe
pain or shivering can interfere with automated NIBP readings. Ensure that the
patient is quiet and not moving during NIBP readings just as you would manual
readings. The patient must avoid applying external pressure to the cuff during
readings. Institute measures to minimize shivering and alleviate pain.
Some arrhythmias may cause beat-to-beat pressure fluctuations that can make
obtaining NIBP readings more difficult. If it becomes difficult to obtain readings in
the presence of arrhythmia, pressure should be temporarily verified using another
method (i.e., ausculatory, oscillometric, Doppler). Pressure also varies cyclically
with normal respiration. With deep respirations or in certain patients this effect
may be enhanced, increasing reading variability.
For patients in shock, indirect methods of measuring pressure (auscultatory,
oscillometric, Doppler) may not be reliable because of peripheral vascular
changes. These changes include peripheral vasoconstriction and diminished
peripheral circulation resulting from shunting of blood to central organs. In some
cases, peripheral pulses or Korotkoff sounds may be diminished or disappear in
spite of adequate blood pressure. In such cases, measuring a cuff pressure may
be impossible or give misleading results. Direct blood pressure measurements
(invasive) should be considered in patients with signs of shock or any patient who
rapidly becomes unstable for unknown reasons.
Setting Up the ABP Monitor
The 90217 ABP must be initialized prior to the monitoring of each patient.
Initialization is accomplished using the 90121 ABP report management system.
(Refer to the Setting Up the ABP Monitor chapter in the 90217 Operations
Manual, 070-0137-xx.)
After the monitor has been initialized, prepare the patient for monitoring as
follows:
1. Turn on the monitor and wait for the monitor to perform self-tests. When the
LCD displays the current time, the monitor is ready for operation.
2. Strap the monitor to the patient on the hip opposite the side on which the cuff
is worn. Secure the monitor using the patient's own belt or the ABP pouch
strapped over the opposite shoulder. When using the shoulder strap, use the
belt supplied with the monitor, or the patient’s belt, to provide additional
security.
3. To select the proper cuff, measure the circumference of the limb at the point
where the cuff is to be applied. Match the limb measurement to the range of
appropriate circumferences (in centimeters) specified on each cuff (refer to
Table 1 on page 4-4).
CAUTION:
• Failure to initialize the 90217 as specified may result in the
display and storage of measurements that are incorrect or
that were acquired from a prior patient. The operator must
initialize the 90217 before each patient use.

Table 1: Cuff Size by Limb Circumference
4. Position the cuff so that the center of the inflatable bladder is directly over the
brachial artery. The center of the bladder location is marked on the outside of
the cuff. Once the proper position is determined, the cuff must be tightened to
ensure that it is equally snug at the top and bottom edges and that it is not
kinked. This is especially important on larger arms. Insert a finger between the
cuff and the limb to ensure it is not too tight. It may be necessary to wrap the
cuff with its tail at an angle to achieve uniform tightness. If the cuff is not
equally snug at the top and bottom edges, the number of readings available
will be limited and the monitor may indicate that the cuff is improperly applied.
5. Once the cuff is applied, the arm should be relaxed at the patient's side. To
avoid reading errors due to hydrostatic pressure differences, the level of the
cuff on the arm should be near the level of the heart.
Cuff Size Limb Circumference
Pediatric 13 to 20 cm
Small adult 17 to 26 cm
Average adult 24 to 32 cm
Large adult 32 to 42 cm
Extra-large adult 38 to 50 cm
!• Use only Spacelabs Medical cuffs with this monitor. Using other
manufacturer’s cuffs may result in inaccurate readings, even if
the manufacturer’s recommended size is observed.
• If the cuff is too small, pressure readings may be falsely high; a
cuff that is too large produces a falsely low reading. The bladder
can be positioned in the cuff for either the left or right arm.
CAUTION:
• Avoid compression or restriction of pressure in the NIBP
patient connector tubes. Check that operation of the
equipment does not result in prolonged impairment of
circulation.
• Do not apply cuff to areas of breached or injured skin.
• Cuff hose connections use luer fittings. Be careful not to
connect the ABP monitor into an intravenous fluid line
when working close to them.
• This product contains natural latex rubber components to
which some people may be allergic. These components
include the bladder and the first four inches of tubing
extending from the cuff.

6. Lead the hose up the arm with the cuff and place it across the back of the
patient. Drape the hose so it does not cause the patient discomfort and is not
pinched shut by too tight a radius. Figure 4-1 shows the most common
positions for the cuff hose.
Figure 4-1: Common Cuff Hose Positions
7. Connect the hose to the monitor.
8. To verify proper monitor operation, take one or more blood pressure readings.
Push the START/STOP key to begin a measurement.
9. The 91343 transmitter must be configured for use with the 90217 ABP monitor
by opening the battery compartment door, removing the battery, and setting
DIP switches 5 ON and 8 OFF. Refer to Figure 4-4 on page 4-7.
10. The 90478 receiver must be configured for operation with the 91343
transmitter and attached 90217 ABP. Touch the monitor ECG key to display
the main menu. Touch CHANNEL FORMAT, then NIBP ON. The monitor will
display the NIBP measurement in a numeric format in the display zone. The
values of the measurement are displayed as ??? until a valid NIBP
measurement has been taken.

NIBP Alarm Message Summary
The 90217 ABP monitor provides an extensive set of result codes that indicate the
status of the monitor and the potential causes of an inability to take a valid
reading.
When any alarm message is displayed, the NIBP parameter value is immediately
changed to ??? and an alarm is triggered. If your module has been configured for
an alarm using the Module Configuration Manager, the parameter display will
blink yellow for Low and Medium priority alarms, and will blink red for High priority
alarms. The alarm condition will persist until a new NIBP reading is taken. (Refer
to the Module Configuration Manager chapter of the UCN Operations Manual).
The following messages are displayed on the UCN monitor to provide ABP status
information to the caregiver. These messages summarize the 90217 event codes.
Some of these messages include an event code in parentheses to provide more
detailed analysis of the event. A complete list of the event codes can be found in
the 90217 ABP Monitor Operations Manual (070-0137-xx).
NIBP UNAVAILABLE (xx)
Displayed when the 90217 ABP monitor has detected an internal condition,
defined by the code (xx). Typically, this indicates a hardware or software failure
that requires that the transmitter be removed from service.
NIBP READING FAILURE (xx)
Displayed when the ABP monitor was unable to make a reading. The code (xx)
defines the cause of failure.
NIBP AIR LEAK
Displayed when an air leak has been detected in the pneumatic system,
preventing a reading from being taken.

Alarm Message Summary
Most of the alarm message priorities in the Ultraview Digital Telemetry system are
user-preset choices in the Module Configuration Manager menus (refer to the
Module Configuration Manager chapter of the UCN Operations Manual). These
priorities are shown in the TONE column and allow selection of one out of four
possible levels.
•HIGH
•MEDIUM
•LOW
•NONE
There are a few priority choices of alarm messages that are factory-preset and
cannot be changed. When one of these choices is selected, a message displays
indicating, “This setting cannot be changed.”
The remaining alarms (and alarm messages) that can be prioritized by the user
are observed according to these preset priorities when multiple alarms are
concurrently active. The alarm with the HIGHER priority is activated and its
associated alarm message is displayed. The alarm message(s) with a LOWER
priority setting(s) in MCM is displayed when and only when the alarm message
with the HIGHER priority is cleared.
Prior to any clinical monitoring session, the user is advised to configure these
alarm priority settings in MCM and select those options that are best suited to the
desired level of patient monitoring surveillance.
Unless otherwise specified in their description, the following messages are left on
the top line (full screen monitors, medium font) or second line (split screen
monitors, small font) of the waveform zone. They are displayed for the duration of
the condition that caused the message or for the period specified in their
description unless replaced by a higher priority message. The conditions under
which these messages can be displayed are outlined below. During alarms, alarm
messages flash unless alarms are suspended.

SpO2 AMBIENT LIGHT INTF.
The ambient light present is causing interference with the signal from the sensor.
Attempt to reduce the amount of ambient light.
SENSOR OFF PATIENT
The sensor is not properly applied to the patient. (This alarm is available only with
non-disposable, finger-clip type sensors.)
SpO2 INSUFFICIENT SIGNAL
The signal amplitude from the sensor is not sufficient.
SpO2 NOISY SIGNAL
The signal is sufficiently disrupted that it may cause erroneous saturation or heart
rate data. This may be caused by patient motion, electrical interference, or other
cause.
NIBP Alarm Messages
The following general messages apply only when the 91343 transmitter is in use
and the NIBP option is enabled on the transmitter and receiver. When any NIBP
alarm is detected, the displayed parameter value (refer to Figure 4-3 and Figure
4-4 on page 4-7) will blink yellow if the alarm priority is Low or Medium, and will
blink red if the alarm priority is High. This is done independently of any other ECG
or SpO2 alarm indications.
NIBP UNAVAILABLE (xx)
The 90217 ABP monitor has detected an internal condition that is defined by the
code (xx). Typically this indicates a hardware or software failure that requires the
transmitter being removed from service.
NIBP READING FAILURE (xx)
The ABP monitor was unable to make a reading. The code (xx) defines the cause
of failure.
NIBP AIR LEAK
An air leak has been detected in the pneumatic system, preventing a reading from
being taken.
NIBP LOOSE OR NO CUFF
The cuff was able to be inflated in a manner indicating that it was not attached to
the patient correctly.
NIBP PATIENT CANCELLED
The patient has pressed the START/STOP button on the 90217, halting a reading
in progress.
NIBP LOW BATTERY
The primary (3xAA) battery voltage is low. Replace with fresh batteries.
NIBP KINKED HOSE
The pressure value increased too rapidly indicating a kinked hose or other
restriction.

NIBP EVENT CODE (xx)
The event code returned from the 90217 monitor is not defined as one of the other
messages.
Telemetry Alarm Messages
The following are general telemetry messages and apply to the 91341, 91343,
and 91347 transmitters.
INTERMITTENT SIGNAL LOSS
Displayed in the waveform zone whenever a minimum of the previous 100
samples were missed. A level 2/low priority alarm tone sounds after 10 seconds in
this condition.
LOW BATTERY
Displayed in the waveform zone when the transmitter voltage is low. This
message is accompanied by a level 2/low priority alarm tone if the SETUP menu’s
LOW BAT ON/OFF key is set to ON and displayed.
SIGNAL INTERFERENCE
Displayed in the waveform zone whenever a signal can no longer be detected
because of interference from a stronger signal source lasting more than 0.5
seconds. A level 2/low priority alarm tone sounds whenever this message is
displayed.
