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.
Propaq Audio Alarm Holdoff with Acuity
When a Propaq Encore in Adult or Pediatric Mode is connected to an Acuity System, the
audio alarms at the bedside Propaq can be delayed up to 4 minutes and 15 seconds. The
delay time is selected in Acuity software at the time of Acuity installation. Visual alarm
indications are not delayed.
