I have started my CPAP treatment in 20/feb with a Philips Auto Dreamstation trial and Wisp nasal mask.
After initial adaptation things seemed to be working well (IAH constantly below 5).
In March 22nd I started another one month trial with Resmed AirSense10 - still using the Wisp nasal mask (nasal mask configuration).
Contrary to the previous Dreamstation trial, I am not adapting well to the AirSense10.
From what I could observe:
- Apparent sudden increases in pressure, causing discomfort - up to the point of 'puffing' my mouth open if I deliberatly close it;
- Much noisier than the Dreamstation had been (corroborated by my wife);
- Frowny red face indicating Mask Fit issues shows up frequently;
I followed instructions from the forum threads and downloaded SleepyHead.
Overview stats and two representative daily stats for each machine are attached.
I have changed the mask intentional leakage values in SleepyHead to reproduce the Wisp manual vent rate curve.
From all I read in previous threads, leak rate was already somewhat high with the Dreamstation machine, but it has skyrocket with the AirSense10 together with 'high pressure' discomfort.
I can't understand exactly why, since it is the same mask.
I have always been a mouth breather, but my sleep therapist indicated a nasal mask initially.
The plateau-like leaks are indicative of mouth breading?
I haven't tried chin straps yet. Will probably give it a go.
Was just wondering why the Dreamstation seemed to work fine - without any discomfort and with much less leakage.
Thanks!
