Are consective 0 AHI possible

I had my CPAP pressure increased to 12-16 about 10 days ago. Since then, the AHI’s have been steadily falling very close to zero. Now they have been flat at 0 ( zero) for the last four days, with no OA’s and no HI’s, only a few RERA’s.
On the face of it, I am happy, but I also wonder if this is normal. If I continue to have 0 AHI’s , does it mean that I am cured? I am aware that in many, perhaps most cases sleep apnea is caused by the anatomy of our respiratory tract, that cannot be modified, but I also wonder if there aren’t other non-anatomical factors that can be eliminated by continued sleep therapy. Also, last night OSCAR reported a large leak at 0.78, but the Resmed daily report, which usually warns of large mask leaks, this time does not mention anything in this regard, with a score of 98%. I wonder why. Thanks

It all depends on how much pressure was needed to achieve the 0 AHI. It may be possible that your pressures are a bit high, but based on your previously posted Daily Reports I doubt it.

OSCAR is much more critical of leaks than the ResMed machine. The leaks have to be really bad for the machine to give you a red unhappy face.

Thanks Usually,the machine shows green faces. The leaks appear only on the Oscar daily log as a percentage.

I recall that your machine is going up to the 15 to 16 cm range for pressure in Auto. If it is still doing similar then the zero AHI just means the machine is doing a good job of controlling apnea events.
