NOTES: SpO
2
alarms are on in all clinical modes (except AED and Manual) unless you specifically turn them
off or alarms for the entire device are off. Once disabled, alarms remain off until they are turned back
on.
While an NBP measurement is in progress, SpO
2
alarms are suppressed.
SpO
2
Desat Alarm
The SpO
2
Desat alarm provides an additional limit setting below the low limit setting to notify you
of potentially life-threatening decreases in oxygen saturation. This additional limit is preset through
Configuration Mode.
NOTE: If the SpO
2
Low Limit alarm value is set below the configured SpO
2
Desat Limit, the Desat Limit is
automatically adjusted to the SpO
2
Low Limit value. Should the SpO
2
reading fall below this value,
the SpO
2
Desat Limit Alarm is announced.
