A BiPAP and CPAP machine is a relatively small device that assists with a patient’s breathing. It is connected by flexible tubing to a face mask worn by the patient. The BiPAP machine helps push air and oxygen into the lungs and then helps to hold the lungs inflated, thereby allowing more oxygen to enter the lungs. BiPAP may be used to support breathing for a number of patient conditions including CPAP or continuous positive airway pressure, it is a treatment that uses mild air pressure to keep the airways open. CPAP typically is used by people who have breathing problems. CPAP also may be used to treat preterm infants whose lungs have not fully developed.
