Extreme Bradycardia and Extreme Tachycardia Alarm Limits
The Extreme Brady/Tachy Alarm Settings menu specifies the configured delta values that are
applied to the HR lower limit alarm and HR upper limit alarm for the Extreme Bradycardia and
Extreme Tachycardia LTA alarm detection, respectively. For example, if the HR lower limit
alarm is configured to 50 and the Extreme Brady delta value is configured to -10, the Extreme
Bradycardia LTA detection threshold will be at 40 bpm. Likewise, if the HR upper limit alarm
is configured to 120 and the Extreme Tachy delta value is configured to +20, the Extreme
Tachycardia LTA detection threshold will be at 140 bpm. The HR lower and upper limit alarms
are not required to be enabled for the Extreme Bradycardia and Extreme Tachycardia LTA
alarm detection to be enabled. The Extreme Bradycardia and Extreme Tachycardia LTA alarms
will not activate until 20 seconds after the alarm limit threshold is crossed.
The following tables list the default Extreme Bradycardia and Extreme Tachycardia alarm
limits for adult, pediatric, and neonate patients, and the ranges in which you can set these
limits:
