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
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.
