NIBP Troubleshooting Guide
Clinical Situation Possible Cause Solution
No NIBP displays ■ Adapter cable not inserted
correctly.
■ Remove and re-insert adapter cable.
■ NIBP not enabled on 90343 or
90478.
■ Enable NIBP function by setting transmitter
DIP switch 5 ON and setting DIP switch 8
OFF.
■ 90217 ABP not properly initialized. ■ Re initialize 90217 ABP using 90121.
■ 90343 Low battery indicator
constantly illuminated.
■ Call qualified service person.
No NIBP readings can
be obtained
■ Incorrect or inoperative cuff in use. ■ Replace with cuff known to be operative.
■ Tubing is kinked. ■ Locate kink and straighten tubing.
■ Some arrhythmias (e.g., 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
patient’s shivering.
■ Blood pressure outside of
measurement range.
■ Verify extremely high or low pressure with
another method.
Intermittent or complete
failure to operate
■ 90217 ABP error. ■ Remove 90217 ABP from service; record
event code; and call qualified service person.
Apparent incorrect
value
■ Wrong size cuff for patient. ■ Measure patient’s limbs at the midpoint;
match limb measurement to range specified
on cuff (undersizing the cuff results in the
greatest degree of error).
■ Cuff is damaged. ■ Replace with good cuff.
■ Excessive patient motion, shivering
or severe pain.
■ Ensure patient is quiet with minimal
movement during NIBP readings; minimize
patient’s shivering.
■ False high readings may be the
result of venous congestion caused
by frequent readings.
■ Reduce frequency of readings.
■ Cuff too loose or positioned
incorrectly.
■ Tighten cuff or reposition appropriately.
