Cuff Fittings
Air system integrity in the NIBP system is essential for 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 cannot 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 noninvasive blood pressure measurements.
