[CPAP] New to CPAP and figuring out how to begin while waiting for consult/tests

Ahh gotcha, so basically it may have just fallen off my nose or face a bit and not pushed air in to me. I do like how minimal the nasal pillows are, but sometimes I think the full nose/mouth cover might be the move for me because I seem to have to adjust it a lot since I'm a stomach sleeper and my face ends up pushing it a bit off center here and there, so maybe that's what happened.

Since you are having a good amount of movement, try the ResMed Mirage Activa Nasal Mask. It is old school big but has bellows that allow for a lot of movement. I slept on my side with 19cmw fixed a lot with this mask. Keep the mask over the edge of the pillow for best results. I do use the P10 pillow as my daily mask.

RE: New to CPAP and figuring out how to begin while waiting for consult/tests
Hey just wanted to share these OSCAR captures since I have a question.

A couple times in the last few nights, if I either woke up with a gasp or jolt into the air or some uncomfortable sensation, I would wait just a little and restart the machine to see it in the data quickly by looking in front of the stop point.

What I noticed is a commonality of the pressure going upward each time this happened, perhaps based on the flow limitation, especially in the first two photos?

What could these flow limitations mean as far as my breathing or reason for awakening? I'm happy I had a score of 0 one of these three nights in this data, but I am definitely still waking up in weird ways and it seems this data could point to something as I try to eliminate that.

Flow Limits are driving your pressure up. Boost your PS to 4

Hey there, good news that I have not had a wake-up-gasping episode since I raised my PS to 4, it's only been a few days but I will continue to see how it goes.

I wanted to attach a new OSCAR example and ask a question since I am curious what the data means. 

What is happening on a technical level between 2:20 and 2:40 in this graph? I know the flow limits can drive the pressure up, but I am wondering what the flow limits mean is happening with my breathing during that time?

I am also curious if my leak rates are considered normal. I do notice the leak rates to be constantly jumping up throughout my daily overviews. I don't notice it leaking out of my nose that much, I do feel some air if I put my hand next to the mask when I am wearing it.

I could be wrong, but it looks like the area around 2:30 had some larger leaks than compared to the time before and after. This caused pressure to go up to make up for the loss.

It does sound like a change to PS of 4 was a good move for you.

As for the mask leaking as you describe, there are vents on the front to allow you to exhale and for the excess air from the machine that you don't breathe in to vent out as well. The air has to escape somewhere. Otherwise, you'd breathe through the mask and your nose and exhale out your mouth, which may be happening at times anyway.

Pawther, your pressure went up due to the flow limitations a flow limitation is a pre cursor for an apnea Resmed treat these with more pressure so the pressure was raised. Then over time the pressure turned to its original levels
