APAP stands for Auto Positive Airway Pressure in sleep medicine?

APAP stands for Auto Positive Airway Pressure. The key idea is that this mode automatically adjusts the pressure delivered during sleep to keep the airway open as needs change through the night. “Auto” indicates automatic adjustment rather than a fixed setting, and “Positive Air Pressure” describes the therapy that provides positive pressure to maintain airway patency. This distinguishes APAP from fixed CPAP, which uses one constant pressure, and from other terms that alter words or order (for example, omitting “Airway” or substituting “Supply” for “Pressure”).
