The measured frequency of all ventilator dyssynchrony and specific sub-types of ventilator dyssynchrony in the landmark studies today, as a function of ventilator mode. IPS=Inspiratory pressure support, VCV=Volume-controlled ventilation, PCV=Pressure-controlled ventilation, PSV=Pressure support ventilation, APVCMV=Adaptive pressure ventilation continuous mandatory ventilation
