Addressing Early Cycling dyssynchrony

An upward deflection in the expiratory flow-time scalar during a patient-triggered breath indicates the presence of early cycling dyssynchrony. This occurs when the ventilator ends inspiration before the patient's neural inspiratory effort is complete. The dyssynchrony can be corrected by reducing the expiratory trigger sensitivity ( E-sense) setting to a lower percentage, there by prolonging the inspiratory phase and aligning it with the patient's neural inspiratory time. In this example, early cycling was partially corrected by adjusting the E-sense from 30% to 10%.
