A few persisting centrals

[Lukie]

I have been using CPAP for a week now. Average usage is 9 hour a night.
It appears that obstructives are almost completely gone as are most of the hyponeas. But there are a few lingering hyponeas and centrals. My AHI last night was 1.3 with 0 obstructives 1 central .3 Hyponea
My sleep study showed an AHI of 6.7 with 1 obstructive,2 centrals and the rest hyponeas.

I'm sleeping much better with control of the hyponeas but why the persisting centrals. My machine is supposed to treat both centrals and obstructives.
I need to change from Quattro air to a less leaky mask, maybe mirage Quattro
I am fine with a full face. Any comments?

If you're getting those numbers after only a week I'd say you're doing extremely well. I know that zero apneas is the ideal but I don't think it's achievable for everybody. You probably shouldn't worry too much.

Have a look at your Sleepyhead charts and see what time the centrals are occurring - I think it's normal to have a few when you're transitioning into and out of sleep.

I also have a few centrals still lingering along with the occasional obstructive. Not sure how long you've been on cpap. I've been on for about 4+ months. I notice my AHI number slowing going down. It still bounces up and down with the occasional bad night, but one night I actually had zero incidents. I think the more used to the machine your body gets, and the better fit you have with a mask, the numbers hopefully get better.

I think I read somewhere that higher pressures can cause CAs. Some day in the future when things have been consistent for a while, I may lower my pressures gradually to see if the CA lessen or disappear. My pressure range is set 5-15. When I look at Rescan, it indicates my 95% pressure is 8-9.
My AHI in the beginning was 3-5, now it is less than one almost every night.

A few centrals during the night are nothing to worry about. As long as the overall AHI is below 5, forget about them.

Some work like mad to get their AHI to zero. Some work like mad to get it to 3. But, really, we should all work like mad to get a good night's sleep so that you feel great the next day. Because feeling great is the key here, not the AHI.

I like what SuperSleeper wrote in "How to find the optimum pressure on your constant-pressure CPAP machine"

Keep a written log of how you feel each morning, afternoon and evening. Note any pain, daytime sleepiness, changes in energy level or mental alertness. Make sure you listen to your body.

Lukie, you are doing extremely well, just continuing doing what you have been doing, the trick with CPAP is to keep everything consistent. Hardly anyone will have '0's every night. You also have to allow for errors, our CPAPs are not sleep studies, sometimes movement in bed can record an apnea. Just on the masks, I used the mirage Quattro for 2.5 years and find there are much less leaks with the Quattro air, but everyone has a different shaped face so if you can try different masks. Do you know what the 95% leakage rate is showing on Sleepyhead?

Be sure to look at the airflow waveforms. Often, when you look at the real data, not much really happened when it says "central" or Hypopnea.

Also, you will sometimes find it's a big whopping, long apnea that you DO need to worry about.
