I looked up paroxysmal nocturnal dyspnea.
If you are starting to get heart failure, does this show up in your inability to get enough air when your breathing demands go up from say after having an apnea. Then by removing the cpap/bipap your able to get your breath back easily. From what I read you would not be able to get your breath back lying down you would have to set up. I can get my breath back from just taking off the cpap/bipap for 15 minutes while laying down and then when everthing goes back to normal I can put the cpap/bipap back on and not have any problems. Yeah I know, this is when you mess up and fall back to sleep not wearing cpap and get really messed up. I have heard of people tearing their mask off and not really waking up. I think I done that one a few times as well.
Is my assumption correct that using cpap/bipap puts a significant load on the heart and lungs and makes it difficult to recover in situations like after having an apnea where your hearts working capacity has been reduced? That would be a reason why people feel the need to tear the mask off while asleep because they can't get enough air.
Anybody know of any studies where they figured out a way to track the hearts working capacity at a reduced oxgen level? So they might say that your heart loses 20% of its working capapcity at a SpO2 of 85. Adrenaline I guess gets you out of that rut where you heart gets weaker from not having enough oxygen during an apnea. I'm making some big assumptions so feel free to correct anything. I do believe that that using adrenaline when the Sp02 level has been reduced takes a toll on the hearts working capacity. I know it has taken me several hour to recover after a bad apnea episodes. Even after several hours, you still don't feel like jumping around that much even though you think everthing is back to normal. Its not. I have found out by going out and doing some activity that your hearts working capactity is reduced so that your heart starts giving off tell tale trouble signs that its done more than it should. If you ignore those signs that the heart is tiring, then you do damage of some sort and feel real bad afterwards. I guess this is when people have heart attacks. They push push push. Got to do this or that. Then the next thing you know your in real trouble. I think each apnea that requires you to trigger adrenaline to get things going does permanent damage of sort. I would like to hear the technical medical jargon on the transformation that occurs in the heart if anyone knows it. It must do damage of sort to the internal workings of the muscle cells.
