Breathing disturbances still causing awakenings?

Where can I find the parameters used to trigger standard flags CA, OA, H, etc? I want to see how those are determined compared to the UF1 & UF2 flags I just enabled.

I figure out that they are flagged if longer than 10 seconds. There must be parameters for flow also.

Those come from your machine, not Oscar.

I'm starting to realize I probably hold my breath when I turn over in bed.

Hi Rob K,

Oscar can show you sleep positions using data from another software called Somnopose. In Oscar, the import function is under Data->Import Somnopose. While Somnopose only supports Apple iPhones, it is is neat in that it uses the gyroscope (or whatever it is) in the phone and records, "Left hand side", "Right hand side", angle data. The idea is you strap your phone to your chest and sleep with it, with the Somnopose software constantly recording the phone's position. Later on, upon importing the data into Oscar, new graph panels will appear that shows your sleep positions, and you can easily correlate it with the other data in Oscar like the Flow and apneas, etc.

A couple years ago, I made an equivalent software that runs on Android phones and generates Oscar-compatible position data (same as the Somnopose data format), because I don't have an Apple. I never made it polished or releasable, kind of a learning experience, but it was useful. In my case, I occasionally get a small cluster or two of obstructive events during a night, not always though. Turns out, which I had been guessing but it was nice to confirm using the position data -- when I'm sleeping on my side, things are great. If I'm on my back, then I'm prone to getting some OAs, regardless of the pressure level. Sometimes, the data showed when I attempt to roll over from one side to another... I don't quite make it... LOL.. and end up on my back for a while...

At the time, I looked into less bulky things than wearing a phone, and there is a company that makes very small 1-inch gyroscope sensors with recording + bluetooth -- neat little things that could be put into a headband or maybe tape it right on the mask itself. I bought one of the sensors, it was inexpensive. It comes with a programmer API, and I considered making an app with it, but I got distracted with other things and never did.

Cheers!

Deficit, sounds like you have put a lot of thought into this stuff. I'm using android. It sure would be nice to have a position sensor that is non intrusive. Then to have that data tie into Oscar somehow would be nice.

Does this look like a legitimate OA? There is a deep breath before it happens which makes me question it. During most nights I get a lot of shorter ones that don't get flagged. Still the same deep breath ahead of the flat line. There's a couple examples in the other chart.

When you post those things, put the event over close to the right side, so we can see more breathing leading up to it,

but, the breathing preceding the events looks like awake breathing to me.

Looks more like arousal/awake breathing to me also.
Iffy at worst.
They aren't always clear cut and easy to tell which way they are leaning.

Sorry about that, still learning how to post charts the proper way. Here's another and hopefully better look at those events.
I thought is was normal asleep breathing leading up to those events but that's why I'm here, to learn.

Have been busy lately and not getting in much studying. Still keeping a log. I've notice that I'll get long periods of waxing and waning. Sometimes it seems to go on throughout a large part of the night. A large portion of my events are during the periods with increased and decrease breathing.

I thought this may be related to back sleeping, but I sleep on my side a majority of the night so I don't know what is causing it. I do see periods of steady breathing but do see a ton of waxing and waning along with events throughout the night. Maybe it has to do with waking periods since I do wake throughout the night maybe 5-10 times.

Any thoughts? Is this what they call cheyne stokes or is it something else? Trying to figure what direction to take my studies.

Here's a period of waxing and waning with steady breathing on both sides. And a more zoomed in version showing the increase and decrease in breathing.

The periods were breathing varies a lot is where the majority of my events happen. They also seem to correlate pretty well with the periods of deep sleep according to my sleep monitor. This is also when I'm waking the most based on how the cpap data looks. If my sleep monitor is somewhat accurate it would suggest that my deep sleep is quite disturbed. That would explain why I feel the way I do.

Right now it seems like I'm having problems with deep sleep. That would pose the question of my sleep monitor being correct or not. My monitor is a Withings/Nokia which is an inflatable pad that you sleep on. It senses breathing and heart rate with changes to pressure on the pad. It also tracks breathing disturbances and gives you a heads up if things are unusual. The data is very vague and of no use if you already know you have breathing disturbances. When I researched it 5 years ago it seemed like the most accurate monitor on the market.

Now to figure out what to do. Is there something I can change? I should look at getting something that monitors sleep position to see how that correlates to what I'm seeing in the data. This will help figure out if I'm having positional problems during the night.

Studying the data more closely, I'm actually waking up during all stages of sleep. There seems to be a definite correlation between deep sleep and irregular breathing as long as my sleep monitor is correct.
