FHR High Alarm

Fetal Heart Rate Monitoring: Fetal Heart Rate Alarms
Fetal heart rate threshold alarms are "latching." This means that a clinician must
acknowledge the alarm using the monitor's
alarm.
Active Threshold Alarm: Press the
component of an active threshold alarm. The visual indications remains present
until the FHR value returns to within the defined acceptable range.
Unsilenced, Resolved Threshold Alarm: If a threshold alarm condition
resolves, prior to being silenced (clinical acknowledgment), the visual and
audible indications both remain present. Press the
cancel both the audible and visual indications.
The simplest example of a high FHR alarm occurs when the FHR value is
continuously greater than the threshold (high limit) for 5 minutes. When data
consistently violates the limit, the time-to-alarm is 5 minutes. See
