ELEMETRY TRANSMITTER (96281)
A
BOUT THE TRANSMITTERS
The patient-worn transmitters are small battery-powered devices
that monitor ECG activity and SpO
2
data (96281-C only) and
transmit this information to the telemetry receiver module.
Each transmitter only uses one channel. The wideband units transmit
four leads; the narrowband units transmit two leads. The
transmitters with a display show four leads.
A label is affixed to each transmitter with its channel number
representing a unique radio frequency. Telemetry receivers are
tuned from the Spacelabs Healthcare monitor touchscreen
to receive the available transmitter frequencies.
All transmitters are assigned a channel number at the factory. When
using telemetry, the receiver must be assigned the appropriate
channel for a patient at the bedside or central monitor. Admission of
the patient is done at the monitor.
Lead Fault Indicators
The 96281 transmitter has amber indicators on the front of the
transmitter case. Each indicator provides the status of its respective
leadwire and flashes if the leadwire is disconnected from the skin
electrode or if the skin electrode makes poor electrical contact with
the patient. It is possible for all lead fault indicators to flash
simultaneously if all electrodes are disconnected. In addition, all
indicators may flash if the transmitter is unable to determine an ECG
waveform.
Up to five standard, disposable, silver/silver chloride chest
electrodes may be connected to the patient. The ECG leadwires are
attached to these electrodes and connected to the transmitter.
The 96281 telemetry transmitter is designed to operate with five
patient leadwires. If you choose to use only three or four patient
leadwires, patient information is still processed, but a lead fault
message will show on the host monitor. An optional leadwire
grouper is available for use with the ECG leadwires (refer to Figure
2-2 on page 2-3).
