Answer to Question 1

ANS: D
The peak flow for this pressure supported breath is 40 L/min. The breath flow cycled at 20 L/min, which is 50 of the peak flow. Therefore, the flow-cycle setting is 50.

Answer to Question 2

ANS: A
During pressure support ventilation, when a breath is delivered, the flow will begin to taper down after a very short period of time. When flow drops to a certain percentage of the initial peak flow the ventilator flow cycles out of inspiration. A time cycled breath is usually a breath that is con-trolled by the ventilator during pressure control ventilation. Pressure cycling is used for intermit-tent positive pressure breathing (Bird Mark 7). Volume cycling is utilized during ventilator breaths on certain ventilators.
