Average Volume-Assured Pressure Support (AVAPS) is intended to maintain which respiratory parameter?

• A. Respiratory rate
• B. Tidal volume
• C. Inspiratory time
• D. Expiratory time

Answer: (B)

AVAPS is designed to keep ventilation consistent by targeting a specific tidal volume. It automatically adjusts the inspiratory pressure support from breath to breath to reach and maintain the set average tidal volume. If the delivered volume falls short because of changes in lung mechanics or patient effort, the device increases pressure support; if the volume is too high, it lowers it. This breath-by-breath adjustment helps maintain adequate ventilation when factors like compliance or resistance vary. The mode doesn’t focus on fixing a particular respiratory rate or timing parameters like inspiratory or expiratory time, which are set by other controls; the primary goal here is to regulate tidal volume.
