What should I share from Sleepyhead?

Last night I had an AHI of 2.49 with a pressure of 17-20. The majority of them were centrals. So I suppose I'll lower the pressure incrementally until they mostly disappear. I usually strap on a weighted backpack to keep me on my side, which tends to reduce the obstructives. Without the backpack I have equal numbers of obstructives and centrals. I'll try 16-20 tonight and see what happens. I have a consistent small leak that I'm wondering about - can leaks cause centrals? And what can I do to stop the leak? I've tried various masks and positions, but nothing seems to help.

PR... you are pretty much one of the experts here. Do you have any suggestions for Dank?

There's not much more a person can do with a cpap at 20cm constant pressure.

If dank thinks that any lower pressure gives worse sleep, then the only thing that could be done (aside from finding out that lower pressures are actually ok) is to move to a machine that allows more pressure.

Whether that higher pressure will reduce the occasional obstructive that's showing up or not, and whether it will exacerbate the centrals that are showing up or not... that's anybody's guess.

can leaks cause centrals?

No, all leaks can do, if they're big enough, is confuse the machine so it can't tell if an apnea is central or obstructive... in which case, resmeds will flag them as UA, unknown apnea.

Sleepyhead showed that the high pressure was causing way too many centrals. I'll try to pllay the balancing game of lowering the pressure until centrals aren't a problem

You may have better luck, now that you're getting more useful data.

I finally did it. I ordered a cheap tongue restraining device, suctioned it to my tongue, and crammed the bulb under a full face mask. I wore a foam cervical collar and a weighted backpack and set my pressure to 16-20. I got this bitch down to 0.3 events per hour. My lips are numb, my tongue is on fire and my bite has shifted painfully, but I FINALLY fixed my sleep apnea. My sleep was still poor, probably because I had an ill fitting plastic vice lampreyed painfully to my tongue. I'm nonetheless very pleased with these numbers.

if there is no improvement in sleep quality...

Agree, focus on sleep quality first, then work on the numbers
