During pressure-controlled continuous mandatory ventilation (PC-CMV),a decrease in volume delivered is characteristic in a decreased dynamic compliance.If lung compliance increased or airway resistance decreased,the exhaled tidal volume would have increased.A leak in the ventilator circuit would also drop the peak inspiratory pressure (PIP).
