11.7.5.1 Arrhythmia Alarm Chains
If multiple alarms overlap, announcing all of the detected alarm conditions would be confusing, and a more
serious condition might be overlooked. So arrhythmia alarms are prioritized by alarm "chains".
11.7.5.2 Setting Arrhythmia Alarm Timeout Period
The arrhythmia algorithm can disable alarm light and alarm tone for designated period of time when certain
arrhythmia alarms are detected.
This function is password protected. For more information, see C.4.6The Other Tab.
• For the following alarms, alarm light and alarm tone cannot be disabled: HR high, HR low,
Tachycardia, Bradycardia, Afib End, Irr. Rhythm End.
• The timeout period is only applicable to the alarms in the medium priority chains and atrial
fibrillation chain. For the alarms in the high priority chain, alarm tone and alarm light are presented
as soon as the alarm condition is detected.
• Alarm indication rules for alarms in the atrial fibrillation chain are the same with those for the
medium priority chains.
