Overview
Digital telemetry ECG monitoring provides continuous monitoring ot
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 wrre 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 01 the transmitter case. Refer to the ECG
chapter in the UCN Operations Manualtcr details regarding electrode application,
Telemetry patients are commonly ambulatory and require optimal skin preparation
and lead application to minimize motion anitact. After the electrodes and lead
wires have been attached, it is important to tape a loop at lead wire close to the
electrode to minimize stress or pulling on the electrode itsell. 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 lollowing 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 lunctional.
- The telemetry receiver module must be tuned to the telemetry transmitters
lrequency (channel number).

All system connections must be made by Space/abs Medical
personnel only.
Leakage currents are not affected by the high level output.
The patient is electrically isolated from the patient monitor by
the HF link.
HNING:
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 OHS 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-rango
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.
ECG monitoring in telemetry is identical to hardwired ECG monitoring. Refer to
lhe ECG. Arrhythmia, and STAnalysis chapters 01 the UCN Operations Manual
for detailed descriptions of configurations, displays, and controls. A brief overview
cl ECG monitoring lollows.
Electrodes
For ECG tracing with telemetry, use silver/silver—chloride electrodes or their
equivatent. Always connect all the electrodes required tor a particular lead,
Missing electrodes may result in the loss of ECG tracing. Refer to the ECG
chapter in the UCN Operations Manual lor inlormation on placing the electrodes.
Some electrodes may be subiect to large offset potentials
WARNING:
& - Use only Spacelabs Medical recommended electrodes.
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.

CAUTION:
- Visually inspect each lead wire for obvious damage and
replace them as needed.
0 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
delibrillation. Non-Spacelabe Medical cables and lead
wires may also change the required input impedance and
DC oilsel voltage, affecting monitor performance.
- Do not use stainless steel electrodes.
- Do not allow conductive parts of electrodes and
connectors, including the reierence electrode, to contact
other conductive parts, including the ground.
- Poor cable dressing or Improper electrode preparation
may cause Ilne isolation monitor transients to resemble
actual cardiac waveiorms and inhibit heart rate alarms.
Reler to the ECG chapter of the UCN Operafions Manual for
details on proper electrode preparation and application.

Pulse oximetry enables you to noninvasively monitor a patient‘s hemoglobin
oxygen saturation either continuously or opisodically. The oximetry sensor
contains two light emitting diodes (LEDs) that transmit speciiic 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 oi light absorbed by the blood can be used to calculate the ratio oi
oxygenated hemoglobin to total hemoglobin in arterial blood. This ratio is
displayed as percent Sp02. Normal values range irom 95 to 100%.
WARNING:
b ' A pulse oximeter should NOTbe used as an apnea monitor.

Setting Up Sp02 Monitoring
The 91343 digital telemetry Mufti-parameter transmitter uses Spacelabs Medical
sensors as well as those from other manufacturers. Refer to Accessories on page
1-13 for information concerning specific sensors.
CAUTION:
- Use only patient sensors specified by Spacelabs Medical.
Using sensors other than those specified may degrade
performance and damage the transmitter during
deflbrillatlon.

- Never attach an Spo, 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
oxlmetry values.
All sensors require an adapter cable between the sensor and the transmitter.
Because the adaptor cable is reusable, do not discard t| when you have finished
using a disposable oximetry sensor. Disconnect the sensor cable from the adapter
cable before discarding the sensor.
To connect the Spoz 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.
CAUTION:
E - Never twist the cable.
