Which statement best describes the key idea for BiPAP?

• A. It is used to provide oxygen only
• B. It uses a single pressure level
• C. It delivers high tidal volumes to exceed dead space
• D. It provides ventilation and oxygenation support, e.g., COPD with CO2 retention

Answer: (D)

BiPAP uses two pressure levels to support breathing noninvasively, delivering both ventilation and oxygenation. The higher inspiratory pressure helps increase tidal volume and improves CO2 removal, while the lower expiratory pressure keeps the airways open and aids oxygenation. This approach is especially helpful in COPD with CO2 retention, where the goal is to assist ventilation and gas exchange without requiring invasive ventilation. It’s not simply about delivering oxygen at a single pressure or pushing large tidal volumes; the dual-pressure ventilation provides the needed support for both ventilation and oxygenation.
