Sleap Apnea

To clarify a recent post, sleap apnea is when you stop breathing in your sleep. There are vaarious types, like central or obstructive, and I'm still learning about these things. Basically, though, for one reason or another, you stop breathing and then, after a few moments, you wake up just enough to start breathing again. In mild cases it happens a few times per night. A severe case is qualified as 50 times per night. Though it varies for Sam depending on a few factors, he stops breathing as often as with every breath, where he'll wake up to take a breath, fall back a sleep on the exhale, and twenty seconds later, he'll wake up to breath again.

A CPAP machine (Constant Positive Air Pressure) pushes are through a mask that covers either the nose or both the nose and mouth at a constant preasure. This forces the airway to remain open and reduces the number of apneas a patient has. It makes it possible for deep sleep to happen without being inturrupted. There are also biPAP machines that have one pressure for inhaling and one for exhaling. I'm not sure what kind of apnea requires this added measure, but Sam doesn't have it.

Hopefully I've explained it well enough, now. If oyu have any other questions, let me know. I'm still learning things, so maybe you have a question that I haven't thought of .
