Non-invasive blood pressure
NIBP troubleshooting
Problem Solution
NIBP measurement does not work or
the values seem unstable.
●
Check that the cuff tubing is not bent, stretched, compressed,
or loose.
●
Check the cuff position and cuff tube connection.
●
Prevent motion artifact.
●
Use NIBP cuffs of correct size.
Why does the mean value display while
the associated systolic and diastolic
values display as - - -?
●
Assess the patient and perform a visual inspection of the
equipment to ensure system integrity.
The following conditions may cause the mean value to display in
the NIBP parameter window while the associated systolic and
diastolic values display as - - -:
●
Very low systolic and diastolic amplitude fluctuations (e.g.,
patient in shock).
●
Very small difference between the mean and systolic pressure
or the mean and diastolic pressure.
●
Loss of system integrity (e.g., loose connections or worn parts)
Why is the monitor re-inflating the cuff
automatically? The cuff target pressure must be higher than the patient’s systolic
pressure to obtain an accurate systolic and diastolic measurement.
If a systolic blood pressure cannot be found, the monitor searches
for a systolic reading by re-inflating the cuff at a higher pressure.
This systolic search may occur once per NIBP determination cycle.
During a systolic search, the maximum cuff inflation pressure
will not exceed the normal pressure range of the cuff. For more
information, refer to the technical specifications.
For PDM and PSM, the monitor may be taking a control
measurement. If the measured NIBP value exceeds the alarm
limits, a single low priority alarm sounds and a new measurement
is automatically taken. If the new value (the control measurement)
also exceeds the alarm limits the alarm priority escalates to
medium. In
Manual mode and STAT mode there are at least
four seconds between the first measurement and the control
measurement for
Adult and Child cuffs, eight seconds for Infant
cuffs. In Auto mode there are at least 30 seconds between the first
measurement and the control measurement.
For PSM, if Weak pulsation or Artifacts is detected, the module
repeats the measurement up to three times. Assess the patient
and perform a visual inspection of the equipment to ensure system
integrity.
For PSM, if cuff occlusion is detected during inflation the module
might repeat the measurement. Perform a visual inspection of the
equipment to ensure system integrity.
