limits are set to alarm at specific SpO
2
levels. When the SpO
2
level fluctuates near an
alarm limit, the alarm sounds each time it violates the alarm threshold. SatSeconds
monitors both degree and duration of desaturation as an index of desaturation
severity. Thus, the SatSeconds feature helps distinguish clinically significant events
from minor and brief desaturations that may result in nuisance alarms.
