Cuff fittings

Air system integrity in the NIBP system is essential to ensure accurate measurements.

Routine wear of the O-ring gasket located in the threaded fitting of the cuff hose can

result in air leaks. If you encounter air leaks that can not be found from the tests in this

manual, replace the O-ring first.

1. Disconnect the cuff hose from the monitor.

2. Using pliers, pull off the metal fitting from the cuff hose.

3. Cut approximately 1/2" off the cuff hose.

4. Using a small screwdriver, remove the C-clip from the fitting.

5. Remove the knurled nut from the fitting.

6. Remove the O-ring gasket and replace it with a new one, being careful not to nick or

otherwise damage the new O-ring.

7. Reassemble the fitting with the knurled nut and C-clip.

8. Press the fitting back onto the cuff hose.

WARNING Use of NIBP channel with leaking cuff hose fittings may result in

inaccurate non-invasive blood pressure measurements.
