I have been using my cpap machine for 3 weeks with a nose pillow. Prior, my AHI was 32. Pretty much immediately after starting it dropped to 5 and below. The last couple of nights it has been 6, even with an indication of mask fitting fine. I realize it’s not horrible but was wondering if anyone had any similar experience or insight into what maybe happening. Thanks
