Alarm activation
Physiological alarms have individual activation criteria as shown in
the table. Alarm annunciation does not depend on case activity.
Checking alarm function
1. Set a parameter alarm limit outside of the current measured
patient values. For example, connect the SpO
2
sensor and adjust
the SpO
2
high limit under the measured SpO
2
values.
2. Confirm that the following alarm notification events occur:
• The audible alarm sounds the correct tone.
• The alarm light illuminates.
• The SpO
2
numeric value flashes in the digit field with the
correct color.
• An alarm printout (if enabled).
3. Audio pause the alarms and confirm that the alarms are paused
and that the left side of the alarm indicator light is a correct
color.
4. Return the parameter alarm limit to the original value.
