Thanks for fixing the link.

In the future, post using imgur (see links below) - much better.

Your data shows a lot of centrals. Do you have a sleep study report?

thanks for cleaning up the links. I tried to follow the dot vs . substitute method from other threads, for those that cannot post. Not familiar with imagur, but dot substitute concept is the same.
Here shows SP02

sorry, sp02 again

How was your sleep quality? Did you find yourself awake for parts of the night with the mask and machine on?
If so that could explain some of those central/Clear Airway apneas.
Often (especially when new to this therapy) we don't sleep so soundly and have considerable time awake while wearing the mask with the machine on and we do some tossing and turning. Our awake breathing is much more irregular than we might think and the machine will sense the irregular breathing and mistakeningly give it an apnea flag. These machines don't know if you are awake or not. They just measure air flow. So sometimes they flag awake breathing by mistake.

At any rate...the hourly index for the centrals was a little less than 3.0 which even if they were all centrals most doctors wouldn't get overly alarmed about this soon into therapy. They would watch them and see if maybe they reduce with a bit of time.

For members unaware of the OP's history.

Home sleep study only...no titration and the home study was short number of hours with either mild or moderate category OSA category. I forget the exact AHI. Wasn't horribly high though.

This was a 3 day trial...I don't know where OP lives to get a 3 day only trial. That's all that is offered in his area.
Then he has to decide if he wants to continue with the therapy.

He's not so sure he really has OSA...he thinks the home study resulted in a false positive.

Fixed the link showing O2 graph for you.

Sleep quality was not great, I used to benadryls to force myself to sleep all night, because I was worried about waking up and only have 3 nights to rent. I am the false positive complainer, and this report was the worst AHI of the 3. So I thought to submit here.

I had this very cold freezing feeling in my nostril that kept irritating me and waking me up, maybe that leakage was a few times with me pushing and pulling around nose pillow to try to align it properly. A few times, I felt it come unsealed and could hear air rushing through.

I did overnight with AHI = 10 and felt the results were innacurate since I was only asleep for about 3 hours an pulled and tugged on nose apparatus during majority of clustered OA events. Came here, whined a bit, tried several alternate methods to try to cooborate data, and learned how to record and plot sleepyhead data, that I used in conjunction with 3 day rental. This is sleepyhead plot of 3rd and worst night (by AHI value). I wrote on the card that I was willing to continue.
Thanks to Pugsy, I'm fairly convinced that the non-constant ramping of pressure is sufficient to give conviction that I have some sleep apnea that could be causing daytime fatigue.

To clarify, it was an overnight lab study that I was concerned about a false positive. I ran several Sp02 studies on my own, and didn't see much evidence to cooborate the positive result (yes, I know they are not as good as overnight polysomnagraphy, but can't afford to keep paying for more elaborate tests right now).
Then I was able to get a 3 night rental resmed 'for her' which I logged data into sleepyhead and posted worst night here. Pugsy has convinced me that the pressure variation is sufficient to guarantee I have sleep apnea. So if the lab comes back and says I need it, I'll go ahead and try to procure one.

My apologies...for some reason I was thinking home study..brain fart I guess.

I wouldn't worry about the centrals until you can say you actually slept soundly for the most part.
Some centrals are normal...like sleep onset centrals and if you had a lot of wake ups then it stands to reason you probably had a lot of falling asleep times when the sleep onset centrals could happen.
Normally sleep onset centrals aren't a problem unless numerous enough to cause serious desats or numerous enough that the person keeps bouncing out of sleep all the time.

Most doctors won't do much with centrals less than 5 per hour other than watch things for a little while.
Give it time for the person to sleep better and hopefully eliminate awake breathing flags and if they are sleep onset centrals again once sleeping more soundly the chance of having a sleep stage transition central will reduce.

Finally if they are product of cpap pressure itself...some people will have the centrals go away with time.

At any rate..most doctors won't do anything with 3 per hour average anyway without other stuff going on.

Given the poor sleep quality..and the fact that you were under a lot of stress to make these 3 days count....I would just keep one eye on the centrals. I don't think that they are meaning something serious at this time.
Now if you still see 3 to 5 per hour after 3 months...then have another discussion.
