Flow Mismatch: Patient Ventilator Asynchrony Associated With Volume Ventilation

From post surgical patients to patients with ARDS volume ventilation (VC-CMV or VC-IMV) remains a very popular modality. Traditional volume ventilation is easy to use and comprehend, extensively available on numerous ventilators, and is able to provide adequate gas exchange by presetting minute ventilation. Additionally, VC-CMV is the most common mode used to ventilate patients with ARDS[i], due to fact that the operator may limit the delivered tidal volume thus insuring a low tidal volume strategy.
