NBP Monitoring: Troubleshooting
LEAK
The NBP cuff is loose or there is an air leak in the cuff or tubing. Check
that the cuff is on snugly. Check the connection between the cuff and the
tubing. Check the connection between the tubing and the blood pressure
monitor. Try another measurement. If the problem persists, contact your
local sales/service representative.
LOW INFLATION PRESS
This message appears when K-sounds are detected immediately upon
inflation. The inflation pressure is too low for proper NBP measurement.
Try another measurement or adjust dynamic/fixed inflate. Refer to the
Setting Test Parameters section in this chapter for more information. If
the problem persists, contact your local sales/service representative.
MOVEMENT
This message appears when there is excessive patient arm movement, or
if the patient’s arm was bent during the measurement. Check the patient
and try another measurement.
SENSOR?
This message appears when the K-sounds on the measurement were too
weak, or not enough sounds were detected. Reposition the microphone
and try another measurement. This message can also appear if the
deflate rate is not properly adjusted. Refer to Setting Test Parameters in
this chapter for more information. If the problem persists, contact your
local sales/service representative.
WEAK PULSE
The patient’s heart rate is erratic. Check that the microphone cable is
plugged firmly into the patient cable, and check that the microphone is
positioned correctly on the patient. Try another measurement. If the
problem persists, it could indicate a defective microphone, microphone
cable, or patient cable. Contact your local sales/service representative.
