HELP needed for OSCAR graph analysis for first time user

[newbieusa]

First time use. Woke up feeling eyes pressured, little bit bloated and bit headache.

I am new user
Used machine for first time today and couple of things noticed
- In night sometimes I went out of breathe I mean i cannot exhale out due to air coming into my nose
- Woke up with pressurized eyes (literally felt eyes heavy)
- Woke up with bit of headache but it went away in few mins
- Woke up feeling slightly bloated

I sleep mostly on my back, some times on side
I do not breathe from mouth (did not as far as i know last night either when using APAP first time)

I am trying to learn how to read OSCAR but here are screenshots and attachment if anyone can help me read and interpret, and see if i can do to have optimal APAP experience

Machine used-  Resmed Airsense 10 APAP
Pressure - 7 to 15
Mask - AirFit N30i Nasal Mask

Here is another screenshot

Unfortunately i cannot modify the subject line

I need help with "OSCAR graph analysis"  and see if anyone can read/interpret and point out the issues or feedback to have an optimal APAP experience

Are you asking for the thread title to be changed to, "OSCAR graph analysis"?
- Red

[newbieusa]

Yes if title can be changed to "HELP needed for OSCAR graph analysis for first time user?", that would be greatly appreciated. 

And if someone can help out with checking out the graph and what i need to do to tune APAP or so, to have proper experience rather than suffering what i did as mentioned in my first post

[Crimson Nape]

Done! I changed it to, "HELP needed for OSCAR graph analysis for first time user". I dropped the question mark.

Thank you I appreciate it

You are having a lot of positional apnea.  Positional apnea can NOT be controlled by pressure changes.  You have to find out what position you are getting into and cutting off your own airway.  Have you changed your sleep position?  Sleeping on your back?  Using more (or new) pillows?  These things can cause positional apnea by chin dropping to your sternum and cutting your airway.  Think of it of a kinked hose – nothing can get through – you have to unkink the hose…

IF you can’t make a simple change like changing to a flatter pillow helps then you will need a collar.  I have a link to collars in my signature at the bottom of the page.  It shows people who are not wearing a collar and the SAME person wearing a collar.  There is a huge difference between the two.

You can easily see positional apnea by looking at the Oa and H events.  When they are grouped together they are positional - almost all of your Oa were grouped (positional).

If you can get the positional apnea fixed that will help the too high pressure (15) you are having.  When air can not get through because of positional apnea the cpap raises the pressure until it reaches the max you have set.  You could set the max lower if you wish so it does not "run away" with the pressure. Maybe max of 10....

Thank you so much for your detailed response

I was not aware there is something called positional apnea as well.
How do I know which position is working for me/or am i in? As far as i know when i sleep i am on my back and sometimes on side, and as soon as morning comes by I usually am on my stomach.
So I guess I would need to find out what position is causing that issue.

I will definitely order a cervical collar, looks promising. I already have a flatter pillow i sleep on. 

I tried fixing the maximum pressure and set it to 12 last night. I think I am less bloated today and bit less eye pressure. But still do have a headache and little eye pressure. 
I also set "Smartstart" = ON. Humidity = ON. EPR = ON (as i was not able to exhale on first day of use due to pressure coming into nose so fast)


I also had to take my mask off early morning as i was not able to sleep properly, I mean i was not able to exhale. 

I may change the n30i mask and replace it with p30i mask so that i can have those mask resting inside the nostril. I think n30i mask moves and leaks when i turn to side as it does not fit properly OR it does not have proper support. 

Here are the new reports from recent night after the above changes.

There is potential apnea during the night so you need to keep looking for an answer for that. 

You have added EPR but I can’t tell what that setting is. If you don’t have it set to 3 do that. 

One important graph is flow limits. They are apnea also. And they drive up pressure. The EPR 3 will help if they are high.

[newbieusa]

Thank you

Attached is the screenshots which shows EPR and flow limits

EPR is set to 1 currently (I will try to set it to 3 tonight and see the difference)

Is flow limits high in this screenshot? what should the ideal be?
