First SpO
2
Event
Consider the first event. Suppose the SatSeconds alarm limit is set to 25. The
patient’s SpO
2
drops to 79% and the duration of the event is two (2) seconds
before saturation again exceeds the lower alarm threshold of 85%.
Because the SatSeconds alarm limit is set to 25 and the actual number of Sat-
Seconds equals 12, there is no audible alarm.
Figure 10-3.
