[Engineer]

If a pressure-support breath on a CareFusion V.I.P. Bird Infant-Pediatric Ventilator is 25 mL and the peak inspiratory flow is 10 L/min, the breath will flow-cycle at _____ L/min.
 
  a. 0.50 c. 1.25
  b. 1.00 d. 2.00

Question 2

A pressure-support breath on a CareFusion V.I.P. Bird delivers 230 mL, and the peak inspiratory flow is 18 L/min. This breath will flow-cycle at _____ L/min.
 
  a. 0.9 c. 3.6
  b. 1.8 d. 4.5

Answer to Question 1

ANS: A
Between tidal volumes of 0 mL and 50 mL, the flow-cycle value is 5 of peak flow. Therefore, 5  10 L/min = 0.5 L/min.

Answer to Question 2

ANS: D
For delivered volumes greater than 200 mL, the flow cycle value is 25 of peak flow. Therefore, 25  18 L/min = 4.5 L/min.
