Last night's sleepy head data- # CA's okay?

Post by Wonderbrah » Fri Oct 21, 2016 4:41 pm

So I'm using a full face mask with Resmed 10 autopap set to 9.0-20.0 pressure. Just wondering if the trend in central apnea events is normal for me? I was diagnosed with obstructive sleep apnea.

Could I be better off using a set pressure to avoid CA's? I was originally prescribed a straight 9.0 pressure based on my sleep study but I was recommended from here to trade in my machine for an auto and increase the maximum pressure to much higher than 9.0

The CAI = 1.16 which is not high enough to be of any concern.

Are you a newbie to CPAP? It's important to realize that a few CAs here and there are not anything to worry about. And in this night, you only have a few CAs here and there.

I would raise the minimum pressure to 10

You didn't say how many CAs you're seeing. If it's just one or two, probably no big deal. If it's a lot, then you need to discuss with the doctor who prescribed the machine.

Sometimes, CPAP pressure can cause Central Apneas, even in patients who were only diagnosed with purely Obstructive Sleep Apnea. It may be necessary to lower the max pressure.

Actually that information is provided on the detailed software report and all a person has to do is click on the link and do a little common sense reading.

FWIW I agree with what RobySue said.
I don't see the need to do anything but shrug the shoulders and move on. I seriously doubt if your centrals are related to your pressures at all and thus changing pressures is unlikely to do anything with the CAs.

Pugsy you beat me to it. Thanks for pointing this out.

Again, thanks for the support.

Why?

The OHI = 0.44 and the HI = 0.88 and there are no clusters of events. So the current pressure level is just fine in terms of controlling the OSA stuff and it's not high enough to be triggering enough CAs to worry about.

Overall, I think this newbie needs to concentrate on learning how to sleep well with the machine rather than starting down the rabbit hole of dial winging with nothing in mind beyond chasing a 0.0 AHI.

It may be taking too much time to get from his current min of 9.0 to what is needed to stop an event. With a med of 13.0 and 95% of 16.56, I would think a modest increase to 10.0 would be worth a try. Plus..the large jump in pressures from 9.0 to 16.0 several times during the night may be disturbing.

Okay, so what about last night's data. A lot of hypopnea's.

Anything I can adjust?

How'd you sleep last night?
How do you feel today?
The pressure sort of went all over the place last night.
Can you get me a screen shot of the flow limitation graph please?

If you have more nights like last night than you do the other night...and you didn't sleep so great and maybe don't feel so great then maybe a little more minimum pressure is in order.
More minimum pressure would be for the OAs and hyponeas and I suspect the Flow limitations (but need to see the FL graph to be sure).
Not sure how much more minimum though.

I always try to find out how a person sleeps and feels and not just base advice on the AHI or pressure numbers all by themselves because numbers alone don't always tell a good story.

Yes, here you go. Thanks for the quick response

I slept okay. I usually take 1 mg of melatonin and a combination of zinc and magnesium(ZMA by Optimum Nutrition). Last night I took neither but still fell asleep quickly, maybe a little less deep overall. Didn't recall any dreams shortly after waking, such as while in the shower like I usually do. My alarm went off of at 9. Kept hitting snooze until like 930. Felt like I could have slept a good few more hours at least. In comparison, the night before with the 2.0 something AHI, I woke up feeling completely rested.

Could you also explain flow limit please? What does it tell you?

Thank you. That FL graph looks pretty much like I expected. FLs are part of what the auto adjusting algorithm will try to squash with more pressure. Your FL graph is fairly active but I have seen worse...and I have seen better.

So how about the answers to my questions as to how you feel you slept and how you feel today?

Is this result with this report a typical example of how your reports look or is this a rare occurrence?

I recently switched from nasal p10 pillows because while, they worked fairly well with an AHI range of 1.0-4.0 or thereabouts most nights, lately I was experiencing an extremely high leak rate even while wearing a chin strap. This is with a brand new P10 mask and straps I bought from cpap.com too. Tried tweaking different things (strap tightness, position, etc.) but couldn't fix it so I switched to the simplus full face mask. I've only been using it for a few nights now so i don't really know what the trend will be.

I definitely feel tired today. Kept yawning in class. Have work later. Will need multiple cups of coffee.

If I were to raise the minimum pressure, what would I raise it to, in your opinion?

Personally I would go to 12,but, do it gradually.
