Continuous positive airway pressure (CPAP), is a positive pressure airway in which a constant flow of air is provided via a face mask.

Overview
Bilevel positive airway pressure (BPAP) is a continuous positive airway pressure (CPAP) mode used during noninvasive positive pressure ventilation. It delivers a preset inspiratory positive airway pressure (IPAP) and expiratory positive airway pressure (EPAP). BPAP can be described as a continuous positive airway pressure system with a time-cycled or flow-cycled change of the applied CPAP level.[1]. Another term for bilevel positive airway pressure, and the term becoming increasingly adopted by the medical community, is non-invasive positive pressure ventilation (NIPPV) or non-invasive ventilation (NIV).[2]
Historical Perspective
Mechanism
Differentiating BPAP from Other Pressure Airways
Continuous positive airway pressure (CPAP), is a positive pressure airway in which a constant flow of air is provided via a face mask. The pressure of this air is determined based on needs of the patient and the condition. This airway has a continuous pressure where as BPAP has two different pressures which machine alternates by itself.
Uses
BPAP and other non-invasive ventilation modes have been shown to be effective management tools for chronic obstructive pulmonary disease and acute respiratory failure.[3] Bilevel positive airway pressure is used when positive airway pressure is needed with the addition of pressure support. Common situations where positive airway pressure is indicated are those where taking a breath is difficult. These include pneumonia, chronic obstructive pulmonary disease, asthma and status asthmaticus.[4][5]
