Continuous mandatory ventilation (CMV)is a full ventilatory support mode.Therefore,a pressure-controlled continuous mandatory ventilation (PC-CMV)rate of 8 breaths/min is not partial ventilatory support.A ventilator rate setting of 8 breaths/min or more is also considered full support.Therefore,even though pressure-controlled intermittent mandatory ventilation (PC-IMV)could be partial ventilatory support,it is full support because of the set rate of 10 breaths/min.Volume-controlled intermittent mandatory ventilation (VC-IMV)with a set rate of 4 breaths/min is partial ventilatory support and MMV can be partial ventilatory support when the patient is participating in the work of breathing (WOB)to maintain effective alveolar ventilation.
