A pediatric patient is being ventilated with a CareFusion V.I.P. Bird Gold Infant/Pediatric Ven-tilator in the assist/control volume mode with appropriately set trigger sensitivity
Physical assessment of the patient reveals the use of accessory muscles during patient triggering. What is the most appropriate action?
a. Turn the sensitivity off.
b. Switch to another ventilator.
c. Turn the leak compensation off.
d. Remove the source of the airway leak.
ANS: C
Leak compensation is used when an artificial airway leak prevents the ventilator from otherwise maintaining the positive end-expiratory pressure level. Small increments of flow are introduced into the circuit to provide back-pressure compensation for the leak. When leak compensation is in use, the patient's ability to trigger may be diminished.
