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 124 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 124).
This setting can only be changed in Configuration Mode.
♦ To view the timeout period configured for your monitor, in the Setup Arrhythmia menu,
see the menu items TimeOut 1st and TimeOut 2nd.
Resetting the Timeout Period
♦ To reset the timeout period, select the Alarms Off or Pause Alarms permanent key and
then reselect it.
