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 91343 or 90478 ■ Enable NIBP function by setting transmitter
DIP switch 5 ON and setting DIP switch 8
OFF
■ 90217 ABP not properly initialized ■ Reinitialize 90217 ABP using 90121
■ 91343 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
