What is the breath termination for a CareFusion V.I.P. Bird Infant-Pediatric Ventilator set to de-liver pressure support at tidal volume = 250 mL and peak expiratory flow 15 L/min?
 
  a. Time cycle at 1 second c. Flow cycle at 1 L/min
  b. Time cycle at 1.25 second d. Flow cycle at 3.75 L/min

Question 2

With a CareFusion V.I.P. Bird Infant-Pediatric Ventilator, a flashing pressure-support display during spontaneous breathing can be caused by which of the following?
 
  a. Pressure support level too high c. Leaks around the artificial airway
  b. High-pressure alarm threshold met d. Decreased volume delivery

Answer to Question 1

ANS: D
Breaths in the volume-cycled mode on the CareFusion V.I.P. Bird Infant-Pediatric Ventilator are terminated using flow-cycling. For delivered tidal volume greater than 200 mL, the flow-cycle value is 25 of peak flow.

Answer to Question 2

ANS: C
Leaks in the system, including around the artificial airway, may result in excessive inspiratory time. This would cause the ventilator to time-cycle instead of flow-cycle the pressure-support breaths.
