Evaluation of My OSCAR Data

Post by mlandau33 » Thu Sep 02, 2021 11:05 am

I would appreciate any thoughts on my OSCAR data. I've been on CPAP for four months and have gone through a number of masks. With the help of many people on this forum, I have found the best mask for me - either Bleeps or the N30. I use one strip of vertical tape over my mouth plus a headband over my mouth. These have gotten my air leaks level down from 60.

Thanks for all the help and support.

Seems like a large number of clear airways events...did your sleep study have a large number of central apaneas events?

it's always a good thing to let us know how you slept when posting a graph. did you sleep fairly well? did you have a lot of wake ups? feel poorly in the morning? and so on.

when someone is starting therapy, they may register what appears to be a large number of clear airway events. and they may find they disappear as their therapy progresses.

or at least, that was the case for me.

I slept reasonably well.
Since I began CPAP several months ago, I've had similar amounts of "clear airway" events, uncorrelated to the number of "obstructive" events. My in-hospital sleep test averaged 1.4/hour when sleeping on my back and 0.2/hour (small sample) when sleeping on my side. What I can tell you, my O2 levels have improved substantially since I began CPAP. On most nights I'm between 95-99 (using a Wellue) 02 ring. Prior to CPAP, I was constantly getting drops well down into the eighties.

Could you post last night's chart, first doing two things:

* Turn off the calendar by clicking the triangle next to today's date.

* Squeeze in the following graphs:

Events
Flow rate
Pressure
Leaks
Flow limitations
Snores.

You can squeeze them into a single screen shot by grabbing the horizontal gray bars that separate them and pushing them up a little.

Will do for tonight's sleep chart (last night was not a good representation because of market-related happenings.

Here goes (note that the large leak around 06:00 was my fault):

Thanks for the reformatting. If you're sleeping reasonably well, you can definitely consider just sticking with your current settings. You might see additional improvement in your daytime functioning if you slept longer, six hours is not enough for many people.

You are seeing a fair number of central apnea events. Judging from your total time in apnea, your CAs and OAs are all pretty short in duration. Some of the CAs may just be 10-second pauses between breaths after a sigh; others may be pauses after an arousal. In the latter case, it's the arousal more than the CA itself that's problematic.

Your flow-limitation graph is quite active, and your machine will tend to raise pressures in response to FLs. The FLs themselves, and the higher pressures, may be of no consequence to how well you're sleeping, or they may be preventing you from sleeping as well as you could. For that reason, I'll present a second option (the first being to change nothing).

FLs can reflect nasal congestion or they can reflect a loosening of the tissues lining the airway, often in the pharynx, or they can be some of each. If you zoom in on your flow rate, you will probably see inhalation traces that are flattened or dented on the top. You need to exert more effort to complete your inhalation, and that repeated effort can interfere with the normal progression of sleep stages.

The best way to treat FLs is to introduce EPR -- expiratory pressure relief. With EPR of 1, for example, your pressure will be 1 cm H2O lower when you exhale than when you inhale, which means it'll be 1 higher when you inhale than when you exhale. This little boost can help you complete your inhalations with less effort. EPR can also be set at 2 and 3. Sometimes EPR will increase the number of CAs, more often it won't.

So the second option I'd suggest is to turn on EPR at a setting of 1. Also raise your minimum pressure to 12; otherwise your pressure on exhale will be 10 (a drop of 1 from 11), which might leave you vulnerable to more OAs (though you have so few this isn't a huge worry). If you try this and it goes OK for a few nights, you could up the EPR to 2, then perhaps later 3.

Your choice, really.

Thanks, Miss Emerita. I have nasal congestion for sure. I've been on allergy shots and nasal sprays which have helped. That six hour sleep amount was really 7.25 hours. The last 1.25 hours showed up a couple of hours later on the SD card. I will follow your advice on EPR and also adjust up the lower pressure limit.

I'll post in another couple of days. Last night got messed up because I did not set up my Bleep Dreamport correctly.
