Continuous positive airway pressure
Continuous Positive Airway Pressure (CPAP)
Continuous Positive Airway Pressure (CPAP) /ˈsiːpæp/ is a form of positive airway pressure ventilator, which applies mild air pressure on a continuous basis to keep the airways continuously open in people who are able to breathe spontaneously on their own.
Etymology
The term "Continuous Positive Airway Pressure" is derived from its function. The word "continuous" refers to the constant flow of air, "positive airway pressure" refers to the method of maintaining the airway's openness.
Function
CPAP is primarily used to treat sleep apnea, a serious sleep disorder that occurs when a person's breathing is interrupted during sleep. It is also used in hospitals to aid in the breathing of patients with severe respiratory issues.
Usage
A CPAP machine uses a hose and mask or nosepiece to deliver constant and steady air pressure. The mask, which can be a nasal mask, full-face mask, or nasal pillow, is connected to the machine via a tube. The machine then generates a flow of air that creates enough pressure to keep the airway open.
