What feature characterizes full ventilatory support in APRV?

• A. It only works during spontaneous breathing
• B. It is effective even when the patient is apneic
• C. It maximizes tidal volume
• D. It does not involve the use of supplemental oxygen

Answer: (B)

Full ventilatory support in Airway Pressure Release Ventilation (APRV) is characterized by its ability to provide effective ventilation even when the patient is apneic. This mode is designed to maintain a specific mean airway pressure that facilitates gas exchange and ensures adequate ventilation regardless of the patient's ability to initiate breaths. By allowing for controlled release phases, APRV supports ventilation while providing an opportunity for spontaneous breaths, catering especially to patients who may not be able to breathe on their own. The ability to effectively ventilate patients who are not breathing on their own underscores the importance of this feature in clinical settings, particularly in cases where patient respiratory drive may be compromised. The other options do not capture the essential attributes of full ventilatory support in APRV; for instance, the mode does facilitate spontaneous breathing but does not rely solely on it, nor is it primarily aimed at maximizing tidal volume or avoiding supplemental oxygen use.
