You have determined your patient receiving volume ventilation has flow asynchrony. How can this be improved? 1. Increasing peak flow 2. Decreasing inspiratory time 3. Adjusting rise time 4. Adding an inspiratory pause
a. 1 and 2 only
b. 1, 2, and 3 only
c. 3 and 4 only
d. 1, 3, and 4 only
ANS: A
Flow asynchrony can be greatly improved in volume ventilation by increasing peak flow and de-creasing inspiratory time. In pressure ventilation, flow asynchrony can be corrected by adjusting rise time.
