Apneas into hiponeas and pressure pulse
#1
Hi everyone,

Hope you slept well.

When i have a good night with really few OAs and CAs it seems to increase my numbers of HI. The breathing of a lot of Hi(well apneas too) seem to restart rigth after the pressure pulse.

Is it the fonction of the pressure pulse? OR is it just to detect the sort of apnea?

Is my understanding correct that some of the HI that would have been apneas?

Do HI affect sleep? Since they are really mild in lenght and often the flow just slow dows i'm under the impressure they dont disrupt sleep and have little to no impact on sleep quality. Is my assertion rigth?

Thank you,

Ghandi

Pressure pulse is your machine's method of discriminating between an obstructive and clear airway apnea. It's akin to the FOT method used by ResMed.

Hi's are often the precursor to OA's. Auto machines respond to them to prevent OA's.
IMO: They are not a significant disturbance to sleep quality.

My machine isnt auto. So i can just speculate those HI's were wanna be apneas.
It surely looks like it.

That's a really good news. I'd trade an apnea for an hypopnea anytime Smile

from: http://en.wikipedia.org/wiki/Hypopnea

"In the context of diagnosis and treatment of sleep disorders, a hypopnea event is not considered to be clinically significant unless there is a 30% (or greater) reduction in flow lasting for 10 seconds or longer and an associated 4% (or greater) desaturation in the person's O2 levels, or if it results in arousal or fragmentation of sleep."

I think having an oxymeter is going to be necessary.

I think it shows that you have your pressure set at the minimum amount necessary to prevent OA events. You might want to bump it up just a tad since 7 cm W.C. is relatively low and you wouldn't notice the difference in comfort or leakage if you go to 7.4 or 7.6 and it might pay off by giving you some margin to cover a night when your conditions may warrant a little more pressure.

You can consider yourself fortunate in being able to control your problem with such a low setting since it makes mask leakage quite easy to manage and that makes your nose and face take less of a beating from the mask. In contrast, I have to maintain a pressure of 17.9 and my mask must be set quite snugly to stop the leaks. I don't recognize myself in the mirror when I first remove the mask. Ohwell

I just traded my ResMed S9 Elite in for a S9 AutoSet but I have found that I still can't install my mask any softer since it will wake me up when the machine bumps the pressure up to the 17 + range in the middle of the night.

Sleep-well

ps. Feel free to ignore all of the above since you don't really have a problem and I can't help but think of the old rule, "If it ain't broke, don't fix it".

I picked up a CMS50F oximeter. I only wear it occasionally.
Price is reasonable; and it gives reassurance that one is not badly desating.

I pretty much agree Ghandi, however two things remain true for you:
First, you need to get that pressure up to eliminate the possibility of those long drawn out OA's you get. But it's great to hear you had a good night last night. So whatever you did, do it again.

Secondly, once the OA's and CA's are taken care of further elimination of the Hypops is useful for better sleep.

Surfie, I think if you will squeeze the range between your min pressure and your max pressure you'll get over that goofy leak situation. Then maybe you'll be able to loosen your mask a little bit and return to that suave, sophisticated looking guy you once were. ............Nah, probably not gonna happen.
