Keep having interrupted sleep - BadSleepIsNotTheWay - 10-05-2020

Hi there,

My issue is that i keep waking up several times a night. I've been using CPAP since May, and in the start i didn't have this issue.

Almost every night, i wake up a few times and feel somewhat tired during the day. It also creates some difficulty getting up in the morning, like the old no cpap days. 

Since I switched from N30I to N20 I've had quite some increase in AHI. Not sure if this is the issue.

at the bottom of the events tab move the slider to 2 - 3 minutes. above that, click on session start times or session end times. then click on a session time. the object is to scroll through your graphs, especially about the last 2 minutes of each session looking for clues to what wakes you. like flow limitations, repeating flow rate patterns (some of these are easier to see at a 7-10 minute scale), leaks, whatever you see. not all awakenings are related to disordered breathing though so it's useful to pay attention when you wake up, noting anything you might think relevant. for example, need to pee, waking slowly or abruptly, panting, anxious, elevated heart rate, sweating, pins and needles, dizziness. use a video camera to see what's happening at the time of the awakenings. use a sleep or snore app that records noise above a certain threshold. also note daytime items that might have a bearing on sleep, like stress, pain, medications, alcohol, types of food consumed. these kinds of things might help narrow it down.

Im having similar problems and I am taking off my mask several times. Together with the PAP machine I use a phone app (it records the sound and movement and shows it as a graph), its usefull to see how much I snored (when I take off the mask) and how many times I moved (it shows that I moved, but it doesn't show what I did). Then Im using a security camera with night vision too to see what I did, as I have recorded when something happened through Oscar and through the app I can just go to that point in the video to see what happened (how many times I scratched myself, if I move my legs, in which position I was sleeping, if I open my mouth when Im sleeping as Im using a nasal mask).



Some things to notice:

I was seeing in my graphs some holes between the sessions where nothing strange happened before I turned the PAP machine off. I cannot look at Oscar to see what happened if I press the start/stop button of a Resmed AirSense 10 Autoset machine (I only tested in this model, but it is possible that it happens in other models too), it trows away 30~40 seconds of recording each time I do that. If I try to scratch my face without turning it off it will record it as a leak, will flag some events that doesnt exist and maybe even raise the pressure that is not needed, if I turn it off it trows away part of the recording and I am not able to know what happened.

In my case some events and isolated leak spikes was just me scratching my face.


You have a leak that is not high but is somewhat constant with low pressure, if your mask is properly fit maybe its leaking through your mouth as you are using a nasal mask. I would suggest you to address that first.

DorMindo: I'm curious how you use your recording sleep app.

before cpap I used a sleep app with a noise activated recording feature. with cpap, it's kind of useless because the sound of the cpap machine obscures all but the loudest noises, potentially missing a lot of activity.

I guess you're commenting, not asking, but I don't quite understand the problem with oscar or the machine throwing away 30~40 seconds when you press the start/stop button. to my knowledge the data can be seen in oscar right up to the end of a session. it should be there to see what might have awakened you, for example. on the other hand, there's usually a 30 to 40 second gap in the graphs from the time airflow starts to the time the waveform shows up in the graph boxes so in my experience you'd miss the first seconds of a session but not the last part.

scratching causing leaks, moving around causing events, etc., are common at the beginning of a session while we're falling asleep and stuff that happens while awake are not important so many of us simply learn to avoid or ignore that stuff.

Hi sheepless.

Im using Sleep as Android, I don't know other apps to compare. I still can see spikes in sound when I move and the app adds a handsaw icon above some of these spikes (it means snore). The PAP machine I use is not that loud, its possible to configure the sensitivity of the microphone in the app, I don't record to listen later anymore. But the camera can record sound too. I still use it mostly because Im taking off the mask several times, then I lose the reports of the PAP machine.

Look at the attachments, there are examples of Oscar, it happened some days ago.

At one day:

At 3:07:42 it shows I turned the PAP machine off for no apparent reason, the breathing pattern did not changed, it doesnt make sense, if I moved to turn it off, the flow rate graph need to change.

At 3:09:20 it shows I turned the PAP machine on again.

Looking at the video, I turned the PAP machine off at 3:08:18, its missing 36 seconds in the Oscar reports. The time I turned it on again is correct. In this ocasion I woke up and drinked water.

At another day:

At 5:04:14 it shows a big leak. The flow rate graph shows flat top shapes indicating a flow restriction, I woke up and took off the mask, but I did not touched the stop button, so the last 40 seconds was not trown away. It can be seen that the last breath changed. I slept again and only realised that I was without the mask 3 hours later, Im using earplugs.

So, I don't think it is reliable to look at the end of a session if the person press the stop button.

I can't say I understand the problem you're describing but if you have smart start enabled, try turning it off. sometimes it results in some weird behavior, especially with some nasal masks. regardless of what the the charts you posted indicate in terms of therapy, from an oscar reporting standpoint they look normal to me. hopefully someone else will have a better answer for you.

I have sleep as android as well. I'd like to use it more but unfortunately, decreasing the sensitivity so it doesn't record cpap noise also tunes out the lighter noises of movement and all but the loudest snores.

I dont have smart start enabled.

Hi BadSleepIsNotTheWay!

Welcome to the forum.
I hope the answers here have been helpful to you.  The posters have a lot of skill figuring out what will help. They helped me a lot!

I use an N20. In fact I've had 4 of them. My sleep quality has been affected by mouth breathing sometimes. 

How are you doing with your sleep? Are things getting better?

After all, if we have to use all this crap while we sleep it had better work!
