NIBP Troubleshooting Guide
Clinical Situation Possible Cause Solution
No NIBP screen key is
displayed
■ Module not inserted correctly. ■ Remove and re-insert the module.
No NIBP readings can be
obtained
■ Incorrect or inoperative cuff in use. ■ Replace with the cuff known to be
operative.
■ Cuff tubing is attached to an adult
outlet, but monitor is configured in
the neonatal mode (or vice versa).
■ Connect tubing to the correct outlet.
Correlate monitor mode, cuff and
patient type.
■ Tubing is kinked. ■ Locate kink and straighten tubing.
■ Some arrhythmias (for example,
atrial fibrillation and frequent
ventricular ectopy) may cause a
single or repeated failure to obtain
a reading (may be due to true
beat-to-beat variations in
pressure).
■ Document arrhythmia if present, verify
pressure with another method, then
follow hospital procedure for care of
this type of patient.
■ Excessive patient motion or
muscle contractions associated
with shivering or severe pain.
■ Ensure that patient is quiet with
minimal movement during NIBP
readings. Minimize the patient’s
shivering.
■ Blood pressure outside of
measurement range.
■ Verify extremely high or low pressures
with another method.
Intermittent or complete
failure to operate
■ Hardware error (codes 10, 20, and
30) detected during previous
measurement.
■ Check the presence of the RESET
NIBP key in the CHANGE CONFIG
menu. Touch RESET NIBP to
re-enable monitoring.
■ Remove the module from service and
call a qualified service person if this
condition occurs repeatedly.
Apparent incorrect value ■ Wrong size cuff for patient. ■ Measure patient’s limbs at the
midpoint. Match limb measurement to
the range specified on the cuff
(undersizing the cuff results in the
greatest degree of error).
■ Cuff is damaged. ■ Replace with a good cuff.
■ Excessive patient motion,
shivering or severe pain.
■ Ensure the patient is quiet with minimal
movement during NIBP readings.
Minimize the patient’s shivering.
■ False high readings may be the
result of venous congestion
caused by frequent readings.
■ Reduce the frequency of the readings.
■ Cuff too loose or positioned
incorrectly.
■ Tighten the cuff or reposition it
appropriately.
