Second Spo Event; Figure 10-4. Second Spo 2 Event: No Satseconds Alarm - Covidien Nellcor Operator's Manual

Second SpO
10.6.2
Consider the second event. Suppose the SatSeconds alarm limit is still set to
25. The patient's SpO
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 15, there is no audible alarm.
