TELEMETRY TRANSMITTER (96281) OPERATIONS MANUAL 3-1
ECG and SpO

ECG Overview
ECG monitoring begins when the system detects a signal through the connection of ECG electrodes or
by installation of a battery into a telemetry transmitter.
Please refer to the operations manual for your
patient monitor for complete information on ECG and SpO
2
setup.
Telemetry ECG monitoring requires the minimum conditions from the list that follows:
• ECG electrodes must be properly attached to the leadwires.
• The leadwires must be properly attached to the telemetry transmitter.
• The telemetry transmitter must have functional batteries.
• The telemetry receiver module must be:
- Inserted in the receiver housing that is connected to a central station, or
- Connected to a monitor that is powered ON.
- Configured to the same channel number as its corresponding telemetry transmitter.
- Connected to a Spacelabs Healthcare diversity antenna.
Patient Preparation and Electrode Application
Use silver/silver-chloride electrodes or their equivalent, and always connect all electrodes required for
a particular lead. Missing electrodes may result in the loss of the ECG waveform.
Note:
Use only Spacelabs Healthcare-recommended electrodes. Some electrodes may polarize and
create large offset potentials. This can compromise recovery time after application of defibrillator
pulses. Squeeze-bulb electrodes, commonly used for diagnostic ECG recordings, may be
particularly vulnerable to this effect.
Noise on ECG signals, especially noise that resembles actual cardiac waveforms, is a frequent cause
of false alarms. Some of this noise may be because of electrode positioning, patient movement or
intermittent signal connections (either of electrode to skin or of leadwires to electrodes). You can
eliminate some of this noise (and many of these false alarms) by paying careful attention to skin
preparation and electrode application.
The telemetry transmitter is color-coded to match the color of the leadwires.
Table 1 on page 3-3 lists
leadwire color and identifier codes.
