Alarm Holdoffs
Propaq Audio and Visual Alarm Holdoffs
Motion artifact or other factors can cause false vital sign alarms.
To help minimize false alarms, the Propaq briefly delays or
“holds off” triggering alarms for certain vital sign limit
violations.
After the alarm holdoff period begins, if the monitor detects that
the patient’s vital sign has returned to acceptable limits, the
Propaq cancels the alarm holdoff. The next time a vital sign limit
is violated, the Propaq starts a new alarm holdoff period. The
following table summarizes the alarm holdoff periods.
When the Propaq is connected to the Acuity Central Monitoring
System, Acuity does not receive any alarm indication from the
monitor until this holdoff period expires.
