hi all, I have a Resmed Airsense 10 for her, lately after having the machine on for approx 5min, I get an error message saying tube blockage, I unplug it, have a look - no blockage - I put it back on, the pressure starts at 4 and after approx 5 min it rises to 10.4 and just about blows my ears out. I take it off, repeat the above process and again, after approx 5 min the same thing happens. when I check the sleep report - it says it ha only been on for less than 30 min however, there is still air going through the mask but it is causing bloating and other embarrassing side effects. I am using the Philips Dreamwear nasal mask. cn anyone shed some light on this for me, I am beyond frustrated and my machine is only approx 3 years old. thanks all
