ASV

Q: ASV is a mode of ventilation that stands for?

A) Assisted support ventilation
B) Adaptive support ventilation


Answer: B

The objective of the above question is to understand this mode of ventilation by its nomenclature. As the name says "adaptive", it is a ventilatory mode that adapts (calculate/adjust) respiratory rate and inspiratory pressure to achieve targeted minute ventilation.


Although weak there is some data to suggest that ASV decreases the weaning of ventilator duration.
