Concepts of Alarm Response Delay
As with any pulse oximeter equipment, the audible and visual alarms are subject to alarm
response delay, which is composed of Alarm Condition Delay and Alarm Signal Generation
Delay. Alarm Condition Delay is the time from the occurrence of the triggering event to when
the alarm system determines the alarm condition exists. While Alarm Signal Generation
Delay is the time from the onset of an alarm condition to the generation of its alarm signal.
The graphic below is a simplified illustration of the concept of alarm response delay and does
not reflect actual lengths of delays.
