Figure 1

Trigger dyssynchrony, double trigger. Display of flow (top) and pressure (bottom) vs time. Note the start of the third successfully triggered breath (red line). In this breath cycle, patient effort initiates a second breath (solid arrows), represented by a quick decrease in pressure at the trigger threshold, such that flow increases. In addition, an ineffective missed effort (dashed arrow) just before the double trigger is demonstrated by an increase in flow and a decrease in pressure.
