Enabling and Adjusting Alarms
Spacelabs Healthcare Technology
Pulse oximetry alarm limits and delays are set internally based upon defined default values. Refer to
the user manuals for your patient monitor for details on operating system alarms.
To enable and adjust SpO
2
alarms (telemetry)
1 Touch ECG.
2 Touch ALARM LIMITS.
3 Touch SPO2 ALARM LIMITS.

Additional Information for Telemetry Products
When SpO
2
alarms are enabled, a bell symbol appears immediately after the measured
SpO
2
saturation percentage (%).
Data Averaging
Data averaging is performed internally on the telemetry transmitter. The data averaging feature
smooths the oximetry saturation value by averaging patient input values over several seconds.
Telemetry
For telemetry monitoring, the heart rate for the display is obtained directly from the acquired ECG
leads. In addition, the pulse rate is obtained from the SpO
2
parameter. SpO
2
pulse rate is viewable in
the patient’s trends and on the 96281-C telemetry transmitter.
Heart Rate Averaging
On-Transmitter Heart Rate Display Performance
The 96281-B and 96281-C transmitters can show the patient’s heart rate when the transmitter is in
view mode. The heart rate shown on the transmitter is to aid patient hook up and is indicative only; it is
not for diagnostic use. The heart rate shown on the transmitter is not related to the heart rate shown on
any central monitor/station. The heart rate is calculated using the QRS complexes detected within the
last five seconds on ECG data. Averaging is performed within the five second window. The heart rate
shown on the screen is updated approximately every 1.8 seconds.
