You will probably need to crack open the case on the unit. find the NIBP tubing and carefully trim each end where they connect to nipples. The tubing has most likely relaxed over the years and is not tight on the nipples anymore. I simple trim of a half cm or a little more and refit them on should remedy your leak issue.

Typical leaks are usually the cuff, hose, hose o-rings or a combination of. Use Snoop or soapy water to look for leaks or swap out with a known good working set.

If none of the above are the issue, you'll have to check for internal leaks. Usually the pump, it's tubing or both have will have leaks and require replacement. This monitor is very old and past EOL. I would suspect the pump has leaks. You may have a hard time finding a replacement pump. If you do replace the pump, you're required to perform a pump calibration procedure.
