How does adaptive-servo ventilation (ASV) work?

ANSWER

ASV devices track how you breathe while you sleep. They react to your breathing pattern and adjust air pressure to help you breathe more normally during the night. If the ASV senses your breathing rhythm is off, it responds with extra air pressure. Once your breaths are steady again, the ASV gently adjusts its air pressure to normal levels. When you�re breathing at a stable rate, your ASV gives you just enough pressure to keep it that way.
