It's about a month I have been on CPAP now. My CPAP is the ResMed AirSense 10 Autoset for Her. I started with the AirFit P 10 for Her nasal pillows, but it caused sores in the nose. I was then given the Phillips Nuance gel system, which stopped the sores. However, its air exhaust is so loud, it would wake me up and it would blow air all over me. I had to go back to the Airfit. At the time of getting into therapy, I used to sleep 6-7 hours with the machine. Along the way, I started shutting off the CPAP in my sleep. When I wake up I find the mask and chin strap have been displaced. I would have slept for 6-7 hours and used the machine for 1.5 hours according to the air report. When I tried the Nuance once again, the report said I used the machine for 3 hours in 7 hours of sleep. My husband tells me about loud noises I make when I have my mouth open in my sleep. Whether it is the Nuance or the Airfit, I always have a dry mouth in the morning and it's causing sores in my throat and the roof of the mouth. I have the humidity at 5 and also use Biotene. Anyone who has faced similar problems and found some solution could share their experience for me? Thanks.
