ResMed AirSense10 Autoset: during the night the pressure goes way up and creates a leak and stays that way

During the night, the machine increases to pressure about 3 fold. The mask loses it's seal and air blows around it. Once it does that it just stays in that mode until I wake up, turn off the machine and turn it back on. Then it's ok for a while. A called my vendor and they had not better advice than to turn it off and one when it happens. There must be a better solution.

Better mask fit may help, but basically that is what autoset CPAPs do. It is turning itself up because it thinks you are obstructing and need the increasing air pressure to keep your airway open. I would guess that your obstruction is worse in your REM sleep and your machine is responding by increasing the pressure. In the past ResMed machines have been rather slow to reduce the pressure after having increased it but this may be linked to the leak you describe. The leak may be interfering with the machines ability to sense your breathing and so it just leaves the pressure up. Hopefully, though, you will become less sensitive to it over time. Stopping the machine and starting it again is what you should be doing when the pressure is too high.

I thought that is how they were designed to work. They ramp up. Mine starts at 5 and I think goes to 12? (I don't remember the exact numbers). When I get up to go to the bathroom and put it back on, it drops back down to 5 and then does the rampup cycle again.

Ramp is very helpful to some new ones starting out on CPAP who are not yet used to the pressure. It helps them fall asleep. However, many experienced PAP users eventually completely stop using the ramp feature once they are used to the feel of the pressure, since they find it easier to fall asleep under the full pressure that prevents sleep-onset apneas.

So if ramp helps you fall asleep, great. But if you keep getting jarred awake as you start to fall asleep, or if you feel starved for air when you first put the mask on, turn the ramp feature off. During allergy season, I like starting out with a pressure of at least 8 cmH2O, sometimes more, in order to feel comfortable using the mask. Otherwise, I feel starved for air, myself.

You need to have your Doctor or clinician check the setting in your machine. It can be set for a range of operation over which the S10 Autoset will change to the pressure you need. My S10 is set for a range of 12 to 14. It usually ends up at about 13.8 average for the night.
