BiPAP® (Bilevel Positive Airway Pressure) is an electronic breathing device used in the treatment of sleep apnea, lung disease, and to treat respiratory weakness. Also known as NIPPV, use of the device overnight improves quality of sleep, daytime sleepiness, and may improve thinking ability. Non-invasive ventilation (e.g CPAP or BIPAP), is another treatment used for respiratory distress. Oxygen is forcefully delivered through a face mask into your lungs
