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 is used to treat sleep-related breathing disorders including sleep apnea. It also may be used to treat preterm infants who have underdeveloped lungs. If your doctor prescribes CPAP over other treatment options for your sleep apnea, your insurance will work with a medical device company to provide you with a CPAP machine and the disposable mask and tube.
