Alarms
Enabling or Disabling Alarm Validation
When the alarm validation is enabled (see
page 275), an alarm condition must exist for a
certain time before audible and visual alarm signals
are triggered. This feature reduces nuisance
alarms.
When the alarm validation is enabled, the time
between the detection and enunciation of a
parameter falling outside the set alarm limits equals
the time of detection plus the assigned alarm
validation delay. For HR, adding the delay time may
exceed the maximum of 10 seconds allowed by
AAMI EC13 and IEC 60601-2-27.
The following table lists which parameters have an
alarm validation time. Parameters that do not
appear in the table have no validation times and
audible and visual alarm signals are triggered
almost immediately.
Parameter Upper Alarm Limit Lower Alarm Limit
ECG/Heart rate (HR) 6 s 6 s
Pulse rate (PLS) 6 s 10 s

Select the validation period for the ST upper-limit alarm in the ST-setup page (see "Alarm Setup for ST" on page 93).

For Nellcor OxiMax SpO2: the SatSeconds alarm time overrides the alarm validation setting (see page 196).
