Alarm on Tachycardias Most tachycardias will alarm in less than 8 seconds. These include AAMI 3.1.2.1 part f.
waveforms. Certain multifocal tachycardias may initially alarm as “low rate.”
Apnea delay setting Adult/Ped = 6, 10, 15, 20, 25, 30 seconds
Neonate = 6, 10, 15, 20 seconds
Alarm Holdoff Time Period a
a. To help minimize false alarms, the monitor briefly delays or “holds off” triggering alarms for limit violations for these vital signs. After
the alarm holdoff period begins, if the monitor detects that the patient’s vital sign has returned to acceptable limits, the monitor
cancels the alarm holdoff. The next time a vital sign limit is violated, the monitor starts a new holdoff period.
HR/PR = 3 seconds (except NIBP PR)
SpO
2
= 10 seconds
RR/BR = 5 seconds
Audio Alarm Holdoff with
Acuity When a Propaq CS monitor in Adult or Pediatric Mode is connected to an Acuity System,
the audio alarms at the bedside monitor 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 and Nurse Call alarm are not delayed.
