Central apnea can affect a person during the day, with lapses in breathing or very shallow breathing because of lack of signaling from the brain, while obstructive apnea is significantly less likely to occur while awake, as obstruction mostly happens due to muscle relaxation and lack of awareness due to unconsciousness.
However when a cessation of breathing occurs (whether or not it is voluntary while you are awake ( "during the day" ), or it is an involuntary cessation while you sleep like in the case of "Central Apnea" ), your brain will automatically attempt to OVERRIDE this cessation of respiration, after a few seconds, which is why you can only "HOLD YOUR ...
This will cut the pressure back on exhale only while you are awake. After you go to sleep it will stop the cutback and make the pressure more effective. Since you likely need so little pressure you could also try it with the EPR on full time. You could also try it with EPR right off. EPR Level: 3 cm. This will drop the pressure 3 cm on exhale ...
When this has happened to me, it has been due to a mask leak, which drove my APAP to ramp up the pressure, With the result that I would awake, trying to exhale against what felt like a hurricane. After turning off the machine, it would revert to normal functioning. That was a RESMED gen 8. I’ve had no trouble with my Gen10.
For me, even some light keeps me awake so I need the room to be real dark. Anyway, the last 10-20 minutes before what sounded like me waking up, I can really hear myself breathe and sometimes it'd sound like I was sighing deeply or taking a little deep breathe. Before that, nothing like that kind of breathing. Last night, it wasn't really like ...
When you stop or slow breathing for whatever reason, you don't instantly run out of oxygen. The left-over oxygen in your lungs is known as your FRC, Functional Residual Capacity. With normal lungs full of air, you are thought to have something like two minutes' worth, normally, though the CO2 buildup happens gradually during that time and your ...
That is the most extreme fatigue that I have experienced. Fortunately that happens only a few times a year. My new CPAP equipment is reporting central apnea. I wonder if there is a relation between that and this experience of feeling that my body will stop breathing unless I consciously inhale and exhale when I am feeling such extreme fatigue.
I question if it's true apnea, because since you're awake and can consciously breathe to overcome it your breathing never actually stops, which you don't do when you're asleep, but the events seem highly related: if it's happening when you're awake, it's probably happening when you're asleep, but even more severely.
OSA is a condition in which the upper airway collapses during sleep resulting in a pause in breathing due to blocked airflow. This leads to recurrent episodes of low bloodstream oxygen and disruption of sleep that can increase the risk of heart disease and affect the ability to achieve restful sleep.
I'm unable to fall asleep while using cpap because at the moment of sleep onset my breathing gets very slow and very shallow, or stops entirely. Then I wake up to breathe. It's not due to obstructive apnea as the machine reports a clear airway at the time of occurrence (in sleepyhead).
