I am so glad you are out there - it makes me feel much less alone.
btw there was a thread about this - but now I've joined and logged in I cannot find it.
I am new to CPAP therapy, but it is great to get a good nights sleep again.
Or it was.....
I had a trial machine for 2 months - the same model Airsense 10 auto. Worked a treat - never missed a beat.
As a member from WA mentioned, the pricing here is Oz is outrageous, so I have bought a new machine online. I new there was a risk without a local agend :( It has worked fine for a bit over a week, and then the last two nights it has woken me and my husband up with a whining air noise when I inhale. And the bigger the inhale the bigger the noise. After a bit more searching before bed last night I found (somewhere on the internet) someone mentioned the seals on the builtin water tank had caused them a problem.
Sure enough, when the noise started after a few hours sleep, I played with the tank, holding it more firmly closed while the machine was still running, and the amount of aiir leakage and hence noise decreased. In the end my hubby had a look at it, and we found that the internal seal in the tank is very loose.
I also noticed that although the inside of the top of the tank is usually misted over with humidity, it was completely dry and clear looking. (I had the humidity set on 3 as on 4 I was getting rainout). I wondered if the escaping air was also bringing downn the humidity coming to me? (less important).
Anyway, after refilling the tank and restarting the machine, with the humidity turned up to 5 (and then adjusted back down to 4 cos it was too wet! in there) there was no more leaking or noise for the rest of the night.
Atm the plan is to see what happens tonight.
But I'm keen to know if anyone else has any insights here, and if it is a flaw in my tank or a feature of the design and hence needing constant adjustment to work quietly??
Please note I am a novice with the machine - only got into the clinical program for the first time last night after seeing online how to do it.... will investigate the sleepyhead software when am feeling brave. :unsure:
