What Is a BiPAP Machine & How Does BiPAP Therapy Treat Obstructive Sleep Apnea?
BiLevel Positive Airway Pressure (also known as BiPAP, or BPAP) machines are a type of non-invasive ventilation device used to treat obstructive sleep apnea (OSA), among other types of sleep apnea and other sleep disorders. BiPAP therapy utilizes two different pressure levels to provide positive pressure ventilation:
-
Inspiratory Positive Airway Pressure (IPAP): Higher air pressure is delivered during inhalation.
-
Expiratory Positive Airway Pressure (EPAP): Lower pressure is maintained during exhalation.
