I am a 33 year old male, recently diagnosed with severe OSA(AHI 35.1) . I had my inlab ( level 1 sleep lab) PSG in March. The test revealed obstructive sleep apnea and no central apnea. It was a split night study with 3 hours for the diagnostic and 3 hrs for the titration with the CPAP. I was hardly able to get any sleep for the titration study but managed 25 minutes of REM sleep. The sleep study indicated treatment of OSA with APAP varying pressure between 4-13.
I started therapy the same week using a Resmed Airsense 10 and an F20 ffm. Struggled quite a bit initially due to multiple issues- mask fit, pressure intolerance etc, but I managed to make progress each day. Finally after a couple of weeks I got a point where I was able to tolerate it for 4 hrs at night. AHI ranged around 3-4 most days. I also noticed a few central apneas but I ascribed it to TESCA. I was also able to fall asleep without the mask if I wanted to.
In order to increase my compliance with the cpap I decided to try a nasal mask. Started using the N20 on April 7th and my compliance went up. The nasal mask was a lot more comfortable for me as a stomach sleeper and it felt less obstructive on my face. I was able to go up to 7+ hours each night with it. AHI went down further, now it ranged between 1-2 most days( central were still there but mostly seemed to be sleep wake junk).
Last week I had to travel overnight, I carried the CPAP along. As I was setting it up in the hotel I noticed that the mask settings were wrong. Instead of the Pillows setting for the N20 it was set as FFM. I changed the setting and went to bed. I was struggling to fall asleep. Initially I thought it was because of the hotel and being away from the bed I was used to but I happened to check the machine and noticed a very high AHI( most of them were revealed to be centrals and hypopneas later when I checked Oscar.).
Ever since that week my AHI has gone up significantly sometimes as high as 7-9. I tried changing masks, pressure settings but still the central and hypopneas persist. I also struggle to fall asleep and have multiple awakenings through the night >5. before last week I did wake up but not more than 3 times in a night. Im surprised that I'm having centrals despite it not being reported in the sleep test. I did a cardio consult not too long ago and heart is fine. Could it be a neurological condition. Im super anxious especially since my grandmom had ALS.
Im attaching my sleep report here in this post. I'll also share a few oscar reports from different dates for reference. Request fellow CPAPers to share their thoughts
