Q. What is the difference between a CPAP mask and a BiPAP mask?

Answer

While continuous positive airway pressure (CPAP) masks have a single pressure setting, bilevel positive airway pressure (BiPAP) masks may be adjusted independently for inhalation and exhalation.BiPAP Masks: The air pressure delivered by a BiPAP may be adjusted independently for inhalation and exhalation. Both IPAP and EPAP stand for Inspiratory and Expiratory Positive Airway Pressure (EPAP).CPAP Masks: The pressure of the therapeutic air delivered by a CPAP mask is fixed and cannot be altered by the user or their sleep therapist. In most cases, treatment for OSA involves the use of a CPAP machine, which maintains a constant air pressure throughout the night.
