I have registered as a member to help out my mom who was just diagnosed with severe sleep apnea. She had the initial sleep study that she was diagnosed on and then the sleep doctor prescriped her an AutoCPAP.
So we are totally new to the world of sleep apnea.
Anyways my question is for the AutoCPAP machine I thought that it sensed her ability to breathe and responded to her, giving what she needed to help out.
But it seems more like it is always on, like when she is just putting it on and getting settled, laying but not sleeping it is already blowing air. Is it supposed to do that? Does it just always blow some air no matter if she needs it or not at that point?
Greetings and Welcome to the Apnea Board!
Yes, the machine is always blowing air. That is the Continuous part of Continuous Air Pressure (CPAP). The intention of the machine to prevent events from happening, not to stop them as they happen. With an Auto machine, if it sees that events are still happening, it will increase the air pressure in an attempt to prevent future events from happening.
It can take some time to get used to it, it is not a normal sensation. But assure your mother that we do get used to it. Many people here have commented on waking up and having to lift up their mask to see if the machine was really on (it was).
Yes, it always blows air. It maintains and airflow to the mask that creates a positive pressure to keep the airway open. An auto machine adjusts pressure within a preset window in response to events to try to maintain an open airway. The "auto" means it adjusts pressure. Straight CPAP runs at constant pressure.
You'll note vents on the mask from which air constantly flows out when the machine is on. That's to purge the mask of exhaled air and the carbon dioxide from breathing.
