Work Shifting, Late Cycling, and Failed Trigger

Work shifting: During early inspiratory phase, the pressure-time scalar is deviated towards the baseline indicating strong inspiratory effort 

Late Cycling: with relaxation of inspiratory muscles and contraction of expiratory muscles the pressure rises above the baseline. Patient completes one breath and starts another breath during the same inspiratory phase (identified by the pressure drop during late inspiratory phase). This pressure drop is sensed by the ventilator and it switches to pressure support within the same breath to deliver additional flow (a feature available in this ventilator, also known as flow adaptation)

This type of patient-ventilator dyssynchrony can happen if there is a gross mismatch between the set RR and spontaneous RR or when the set inspiratory time is much longer than the neural inspiratory time.
