Change in ventilatory pattern over time.. Legend: Flow and inspiratory time tracings at the beginning of treatment (A), and at 7 months (B). Note that at the beginning of treatment (A), with spontaneous ventilation, the inspiratory time varies cycle by cycle; at 7 months (B), with controlled ventilation cycling, the inspiratory time is fixed and prolonged.

In Fig. 1 we can see the changes in respiratory pattern in spontaneous and controlled ("captured") ventilation, with an increase in inspiratory time.
