What defines the BiLevel Positive Airway Pressure (BiPAP) mode?

BiLevel Positive Airway Pressure (BiPAP) is characterized by its use of two different pressure settings: one for inhalation (inspiratory pressure) and another for exhalation (expiratory pressure). This distinct feature allows for improved ventilation and comfort for patients who require respiratory support. The inspiratory pressure is higher to assist in the delivery of breaths when the patient inhales, while the expiratory pressure is lower, which facilitates natural exhalation and decreases the work of breathing.

The other options do not accurately represent the primary function and design of BiPAP technology. A single fixed pressure would not allow the necessary flexibility that BiPAP provides, which is essential for managing variable breathing patterns. Additionally, BiPAP is not solely a method for high-flow oxygen delivery, nor does it rely on an oxygen concentrator exclusively, as its primary function revolves around managing airway pressures rather than just providing oxygen.
