The larger "flat-top" pressure curves represent patient-triggered,pressure-limited,time-cycled breaths from the ventilator.The smaller "flat-top" pressure curves represent patient-triggered,pressure-limited (pressure-supported)spontaneous patient breaths.Pressure-supported spontaneous breaths between patient-triggered ventilator breaths are depicted in the figure.This is intermittent mandatory ventilation,and,more specifically,it is pressure-controlled intermittent mandatory ventilation because the ventilator breaths are pressure limited.
