Answer to Question 1

ANS: A
Double triggering is usually a result of the patients' ventilatory center wanting a larger breath or a longer inspiratory time than is set on the ventilator. This causes the patient to continue inspiration when the ventilator transitions into the expiratory phase resulting in the ventilator triggering a second time. The biggest problem with double triggering is that normally there is no exhalation after the first breath, so that the actual delivered tidal volume may be up to double what is set on the ventilator. Double triggering is most common with volume A/C because of the precise setting of the tidal volume.

Answer to Question 2

ANS: B
Cycle asynchrony occurs when the ventilator ends the breath at a time different from when the patients' respiratory center wants to end the breath. It is more common in pressure than vol-ume-targeted ventilation, but it can occur in all modes of ventilation.
