What mode delivers spontaneous breathing support with two CPAP levels, IPAP and EPAP?

Bilevel Ventilation Continuous Positive Airway Pressure Assist-Control Ventilation Synchronous Intermittent Mandatory Ventilation

Correct Answer:

Bilevel Ventilation

Explanation:

Two-pressure spontaneous breathing support is provided by bilevel ventilation. The higher pressure during inspiration (IPAP) gives inspiratory pressure support to increase tidal volume and reduce work of breathing, while the lower pressure during expiration (EPAP) keeps the airways open and prevents collapse. This setup differs from CPAP, which uses a single continuous pressure, and from modes like assist-control or SIMV, which are time-based and deliver breaths at set intervals rather than a two-tier pressure scheme. So the mode described is bilevel ventilation, often called BiPAP.
