Good Afternoon, Emerita.

I tried to do a chart like yours. Are you saying that I am waking up to breathe because of build of of CO2? I recall one thing that they were very concerned about when I first went in was that my CO2 was very high which is one reason I was in for 8 nights and not overnight as I was told. I had arterial blood taken daily I think.

In doing this graph, I noticed the mask pressure graph had the same look to it at the same point. I don't know what mask pressure is. The pressure was 12 when the graph you see was like this. It did not get higher. My machine is set from 12-20.

I turned on the snore but nothing shows and I assume it will not until I reinsert card and use it tonight.

Thank you.

It looks to me as though you slept right through that CA, though of course it's impossible to be sure.

"Are you saying that I am waking up to breathe because of build of of CO2?" No, what I was describing was the other way around. A brief arousal (wake-up) followed by a CA. The arousal involved deeper breathing, which can reduce the amount of CO2 in your blood, which reduces your drive to breathe. During the CA, the CO2 builds back up, and then you start breathing again.

As your posted segment suggests, not all CAs are triggered by arousal breathing.

Your CA index varies from one night to the next -- that's very common -- and it doesn't ever get high enough to suggest you have a cause for concern. But you should discuss these issues with your doctor to get his/her professional opinion, especially give your problems with CO2 levels.

Yes, Miss Emerita, am waiting for a phone consult. Decided not to go in overnight in this present situation. Thank you for all your help.

Any idea as to why mask pressure matches CA?

Thanks.

Not sure how the mask pressure matches CAs. Could you say more?

Your machine won’t change the pressure in response to a CA. It responds to OAs, Hs, FLs, and snores.

Good evening Emerita. I have posted two pics. Mask Pressure does not mean the air pressure from achine which is set to 12-20. That is just called pressure. No idea what what mask pressure is.

I spoke with consultant today. I was supposed to goin on the 24th but it has been cancelled.

He was very pleased with my results. From dying in August 2019 and not expected to last, my AHI was 60+ and my left EF was under 40. Now over 53% and my average AHI under 2.

Since I have been wearin g the nose clip, my readings have been more stable. He rtold me that my Airsense 10 is very sen sitive and I ought not worry too much if it records a lot of CA as I am probably being aroused without me knowing and they are false + or something like that.

He also said that yes, they know that a high carb meal vastly reduces AHI, sometimes to 0, but it is as yet not known why. I generally eat low carb and it was only because I ate a high meal that I found out.

They don't want to see me for a year unless a problem develops.

I feel very well. Lost another 35lbs since I stopped the Bisoprolol on November 11th.

Am having a 24hr halter next week.

A sharp nurse in ICU who discovered my SA saved my life. Wish I knew she(it was a she)was.

I didn't know one could feel this way.

It’s wonderful to hear that things are going so well for you! Many thanks for updating us.

The consultant may have been referring to the fact that arousals from sound sleep are sometimes followed by CAs. The problem isn’t so much the CA as it is the arousal.

As you sleep better, you may see fewer CAs, and they can also just dwindle with time.

I hope you’re on an upward spiral here—sure sounds like you are!

Thank you, Miss Emerita.

Yes things are going well. My reading last night, normal eating, was 0.5, and I got up 2x for a pee. 5 CA Nothing else. Wasn't my best sleep. I had planned to swim today but as I have puppies due imminently I realized I can't risk being too tired to stay up all night if needs be.
