If the patient is being ventilated via a mechanical ventilator via intermittent mandatory ventila-tion with partial ventilatory support, what would probably happen to PaCO2 if the patient sud-denly had no spontaneous breathing?
a. Increase
b. Decrease
c. Stay the same
d. Change according to FiO2
ANS: A
With partial ventilatory support, if spontaneous breathing ceases or becomes inadequate, as may be the case with the development of rapid shallow breathing or apnea, alveolar ventilation may decrease, and PaCO2 may increase above an acceptable level.
