17 Monitoring Noninvasive Blood Pressure
147
NOTE
Be aware that a combination of a recorder speed of less than 3 cm/min and a repetition time of less
than five minutes can result in not all noninvasive blood pressure measurements being recorded on the
fetal trace. For example, if the recorder speed is set to 1 cm/min and the repetition time is set to
2 minutes, due to the low speed setting, the recorder will only be able to record every other
noninvasive blood pressure measurement. This affects only the local fetal trace recording, and all
measurements are displayed as normal on the monitor's screen.
Choosing the Alarm Source
You can monitor for alarm conditions in systolic, diastolic and mean pressure, either singly or in
parallel. Only one alarm is given, with the priority of mean, systolic, diastolic.
If mean is not selected as alarm source ( Sys. , Dia. , or Sys & Dia selected), but the fetal monitor can
only derive a mean value, mean alarms will nevertheless be announced using the most recent mean
alarm limits. Check that the mean alarm limits are appropriate for the patient, even when not using
mean as the alarm source. When no value can be derived an
NBP MEASURE FAILED
INOP will be
displayed.
Assisting Venous Puncture
You can use the cuff to cause sub-diastolic pressure. The cuff deflates automatically after a set time if
you do not deflate it.
