A continuous positive airway pressure (CPAP) machine was initially used mainly by patients for the treatment of sleep apnea at home, but now is in widespread use across intensive care units as a form of ventilation.
CPAP stands for continuous positive airway pressure and is the most popular treatment for obstructive sleep apnea. CPAP works as a âsplintâ to prevent airway collapse and obstruction, the main causes for periods of apnea and snoring. The CPAP machine uses pressure to gently blow air into your airway, keeping it open.
