Ultraview Digital Telemetry
2-2 071-0774-00 Rev. A
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.
