BiPAP (Bilevel Positive Airway Pressure)
BiPAP (also known as BiLevel) is similar to CPAP therapy; however, with BiPAP therapy there are two different pressure settings for the patient. BiPAP therapy is used to treat patients with breathing disorders beyond sleep apnea. The BiPAP machine is able to be set at two pressures: an inspiratory and expiratory pressure. The dual settings of the BiPAP machine allow patients with compromised lungs, a more effective inspiration. BiPAP therapy is useful for people who have congestive heart failure and various types of lung disorders. BiPAP therapy is also used in treating central sleep apnea, a sleep disorder characterized by failure of the brain to signal the chest muscles to breathe.
