A CPAP machine is a medical device that delivers continuous positive airway pressure to the airways. It prevents alveoli collapse during exhalation and increases functional residual capacity in the lungs.
In Our Own Words
CPAP stands for continuous positive airway pressure, and a CPAP machine can treat certain types of breathing disorders. It works by delivering a set amount of air pressure into the airways and lungs, which helps keep the airway open and helps you move air in and out more with less blockage, or obstruction. Its a familiar device for many who have obstructive sleep apnea. CPAP may also be used to treat infants whose lungs have not yet fully developed.
When used at home, a correct pressure is determined by the doctor and programmed into the machine. A small mask goes over the nose, which blows the set air pressure to keep the airway open while you breathe.
Symptoms and Side Effects
- Dry nose
- Pressure sores around the mask
- Nasal congestion
