What is the ideal AHI for someone using a CPAP machine?

Your AHI, according to the literature, but also according to the insurance industry that underwrites the machines and their replacements for those being reimbursed or provided, should be less than 5.0 events per hour. IOW, 4.9 or less is deemed to be 'treated.' Those of us who hang around fora and help people to dial in their prescribed flow/volume, or to make them more comfortable with their devices, feel that 4.9 can almost always be halved.

You might benefit from dropping into apneaboard.com and reading....a lot. Hours. And, at the top black marquee, to the right, you'll find a link to OSCAR. That is a free, safe, in-house software that will read your machine's SD card once a week or month, daily if you're that keen, and will show you a complete and comprehensive breakdown of all types of 'events' per hour over each night, and give you your leak, flow limits, peak pressure, and other data.

I don't know where you were advised that 14 events per hour comes remotely close to 'treated', or satisfactory. As I stated earlier, you want to be less than 5, and most of us manage to find ourselves at 3.9 or less. My monthly average for the past six years is around 0.6 events/hr.

It's worth a look!

I whol;eheartedly second this recommendation. My sleep med people got mine down to over 10 and suggested that's the best they can do. Ha!

Per gloaming's and others' advice, I've been using OSCAR to figure the adjustments better and have since worked it to consistently under 5. My target was 3 or less.

One of the suggestions was to let the machine auto adjust within a range and gradually increase the pressure range up until a) you can see the apnea score go down and b) you can see that the observed pressure no longer bumps up against the maximum pressure.

I have a follow-up with sleep med this week and let's say that will be a interesting conversation!
