A medical device that helps people, who cannot breathe normally, oxygenate their lungs. The oxygen they need can be delivered via either a nasal prong, mask, or a tube (see ventilation).
The CPAP machine pushes air into the mouth and nose directly or through a mask at a continuous rate, keeping airways open and increasing the amount of oxygen entering the lungs. This combination is why it’s called continuous positive airway pressure – air is continuously delivered to the airway. CPAP is a treatment given to people with COVID-19 who experience respiratory distress.
