I have had my Air Sense 10 Autoset for 3 months. The last time I cleaned it then plugged it in the machine was blowing too much air (pressure starts at 5 then 2 minutes later it goes up to 18, I’m not able to breathe and have to take the mask off). The machine made a lot of noice where before the was no sound of air being pushed. None of the settings had been changed and every time I did a mask fit test it showed that the mask was not fitting properly. I unplugged the machine at least 3 times and the same issue kept occurring (pressure would increase too much and the machine claimed the mask was not fitting correctly). I made an appointment with the tech that I originally got the machine from. I called twice and was told that I needed to make an appointment with my doctor so they could change the prescription. I knew that there was an issue with the machine so instead I emailed the tech and scheduled an appointment so he could check the machine. It turns out that the flap where the tubbing connects to the mask was stuck and that is why so much air was being pushed at one time. The tech unstuck the flap and now the machine no longer made a lot of noise and did not push out too much air. Make an appointment with your tech first so they can check the machine. The problem was solved so simply by unsticking the flap in the bottom of the mask that regulates the air flow. Hope this helps.
