I have long covid and was finally scheduled for sleep study. Though I never had problems with sleep apnea before covid that I know of (?) my test came back that I have obstructive sleep apnea and I also have somewhat Central sleep apnea at this point.

I was put on a CPAP with what I just call a nasal sling kind of, unfortunate that I don't open my mouth during sleep at all and so I can do just a nose thing. This is just a thin silicone tube with a whole cut in it that goes over my nostrils only.
I am in my fourth week and I've already passed the test for medicare. My first night on CPAP I used it for 10 hours.
My pressure is set between 5 and 10 and my understanding from my DME is at night time I'm always at 10. When I put it on and I'm on 5, (I don't use ramp) I can't breathe so well. This morning when I woke up I could breathe great with it on. For like 30 minutes at which point my awake pressure should have dropped to 5 by then but when I looked the pressure was at 8.5 still
and I could breathe great. Now if I can just get my sleep doctor to increase my pressure range to higher than 5-10 five isn't enough for me to have it on when I'm awake and they say when I'm asleep I'm always at the max they have set of 10 so clearly I need higher pressure.

I'm still in my first 30 days so what do I know right?
Here's what I know. Except for two days when my machine wasn't working correctly, I have used it every single night for at least 8 to 10 hours since the day I got it. I use the respironics dreamwear headset where the tube comes out the top of my head. The nasal pillows don't work for me even tho.yhe DME wanted me to use them for some reason. I have ZERO air leaks, and I am very very claustrophobic! My advice is going to be to keep trying different headsets and different pillows nasal pillows slings masks whatever until you find one that works because since I've used CPAP for less than a month now my life has changed. My long covid has changed. Don't give up. Now if I can just get my sleep doctor to change my pressures...
