What is meant by an alarm?
During most monitoring sessions things occur which are to some extent unexpected or
outside normal routine. These are referred to collectively as alarms, even though many of
them are not in the least alarming. Note that the use of the clinical terms "Tachycardia" &
"Bradycardia" for the high & low rate alarms do not indicate clinically pathological
conditions, they simply alert the user that the fetal heart rate has met the user set criteria.
These alarms must not be relied on to detect pathological heart rate
patterns.
Alarms include:
•
Signal going outside the user set range
•
Loss of signal
•
Elapsed time counter
•
Failure of the FM800E unit
Of these, the first requires the attention of a responsible clinician. The signal going outside
the user set range is sometimes cause for concern, and sometimes not.
Other so-called alarms are unlikely to be cause for alarm at all.
