Arrhythmia Alarm Timeout Periods
Normally, an arrhythmia alarm is announced when an alarm condition is detected. However, there are
certain situations that can inhibit the audible and visible indications of the alarm even though the alarm
condition was detected. These include:
• if a more serious alarm condition is active in the same chain
• if a timeout period is in effect for a particular alarm
• if a timeout period is in effect for a higher alarm in that chain.
See “Arrhythmia Alarm Chaining” on page 137 for more details on alarm chains.
What is a Timeout Period?
Timeout periods are automatically started when a yellow arrhythmia alarm is detected. During this
period, the same alarm condition will not generate another alarm. Alarm conditions further down the
same arrhythmia alarm chain will also not generate an alarm, but alarms further up the chain will: see
“Arrhythmia Alarm Chaining” on page 137.
To view the timeout period configured for your monitor, in the
Setup Arrhy menu, see the menu items
TimeOut 1st and TimeOut 2nd.
This setting can only be changed in Configuration Mode.
** AFIB and ** Irregular HR alarms do not have a timeout period. These alarms can be generated
immediately after the corresponding end alarm was generated.
When
** HR High and ** HR Low alarms are configured as standard yellow alarms, they do not have a
timeout period.
Resetting the Timeout Period
To reset the timeout period, press the Alarms key and then reselect it.
