What is a BIPAP machine?

Bipap Machine is used in sleep apnea treatment. Patients with BiPAP-treated obstructive sleep apnea have a face mask while they are sleeping that is connected to the BiPAP  that forces air into nasal passages at sufficiently high pressures to overcome airway obstructions and promote normal breathing. During inspiration and exhalation, the airway pressure in the upper Airway is continuous.
