AHI going up

Hi everyone so I've been on the CPAP for about 2 months so far and have noticed some improvement not much but I have . But lately this past week I've been starting to get sleepy again and have noticed that lately my AHI has gone from 1-1.8 to going up to 2.5 even up to 4. Yes that's not a high number I know BUT I don't know why when I wake up I FEEL the diffference rather then when I was getting the <1.8 . I'm not sure what could be causing the sudden change . I deal with mild depression and anxiety and it was helping me out with it but now that my AHI is going up again my depression is coming back. Any ideas of why my AHI could be going up? I've checked if leaks have been a problem and so far my machine reads that there's barely any leakage. My equipment is pretty new so I don't see any damage. Any other ideas ? My machine is the resmed airsense 10 with a full face mask . I'm 22 years old weigh about 190 lb.

Was hoping one of the more medical folks would answer. I am not a med pro so take what I say with a grain of salt. Your apnea is counteracted by positive air pressure from the CPAP. The positive air pressure keeps your airway open and hence the apnea incidents are mitigated. It is a "mechanical" thing.

If you remain on therapy and there are no major mask leaks and your AHI goes up and you feel more groggy during the day, the issue of mild depression and anxiety seem to be the things that may be contributing to higher AHI and the groggy feeling. Best to discuss with your doctor as I am not sure anyone here is qualified to speak to these things but the more knowledgeable might have some idea whether the mild depression and anxiety or other issues may lead to higher AHI.

Good luck and hope someone smart chimes in but if not, the doc is your best bet! Good luck.

Hi Yayoe10. There can be several reasons you sometimes see a higher AHI. Medications can contribute if you have taken anything different that causes relaxation, and some people have sleep apnea that worsens when they sleep in different positions (like on the back). If you continue to experience these slightly elevated AHIs and believe it is causing you to not feel well, consider talking to your sleep physician. It might also be that your machine pressure just needs a slight adjustment. Your home care company and/or sleep physician should be able to determine this by monitoring the data from your machine. Hope this helps, and please let us know how you're doing!
