And - mesenteria - I actually believe the pink shaded areas in the chart is Variable Breathing. I have a lot of those. And I looked closer to this night's charts. Maybe those periods of VB is my problem. They co coincide with my shallow sleep. I woke up at around 3:30 when I had a long period of VB together with CA and H. Then frequent VB from then on - and I never really slept well after that.
I am not sure what VB even is, but I did zoom in most of those episodes, and it is clear even to a novice such as myself that they always start with some interruption of the normal breathing pattern. And I also frequently get other events during those VB periods.
So what happens when I go into VB? Why? And can anything be done about it?
I am hoping that someone will be kind enough to take the time to look at all these charts, which all show the period before most of my VB episodes and the first part of them.
First chart, the first VB episode. I seriously question this, since I was not even sleeping yet. I turned the CPAP on at 22:47 and the VB started at 22:49..? I know for sure I did not fall asleep in 2 minutes. It even flags a Hypopnea right before the VB. While I am awake. And I cannot see any pause in the breathing. Is this really a Hypopnea? Or is my machine giving false alarm?
Second chart, at 00:20. Some irregular breathing and then entering into VB.
Third at 01:39. A pause in my breathing prior to the VB. A pressure pulse and an H during the VB. Note how my pressure does not change despite the H. Is this because the VB algorithm in the machine I read about?
More charts in next post.
