Digital Telemetry
General Telemetry Overview
The 90478 digital telemetry receiver module, when used in conjunction with
Spacelabs Medical telemetry transmitters, an Ultraview 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 90343
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 SpO
2
measurements and episodic
noninvasive blood pressure (NIBP) measurements.
One operational mode is available with the 90343 and the 90347 multi-lead
transmitters. When all electrodes are connected to the patient, leads I, II, III, AVR,
AVL, AVF, and Vx are available. When no chest lead is applied, leads I, II, III,
AVR, AVL, and AVF are available using the remaining connected electrodes.
ECG monitoring in telemetry is identical to hardwired ECG monitoring. Refer to
ECG Setup on page 8-4 for more information.
For more information on SpO
2
and NIBP monitoring refer to Setting Up SpO2
Monitoring on page 14-4 and Multiparameter Telemetry (NIBP) on page 17-17.
