Application progress of mechanical ventilation in acute respiratory distress syndrome

Mechanical ventilation is essential in the treatment of acute respiratory distress syndrome(ARDS).Mechanical ventilation mode and parameter set are extremely important for improving the prognosis of patients.Research data have shown that low tidal volume ventilation(＜ 6 ml/kg predicted body weight,and plateau pressure is less than 30 cm H_2O)can reduce mortality and is standard treatment for ARDS.The individualized positive end expiratory pressure ventilation is also a promising study direction.Other methods such as prone position ventilation,alveolar recruitment can not be used as routine first-line treatment,but only be used.as rescue treatment under severe hypoxemia.Additionally,this article also reviews some characteristics of mechanical ventilation on the treatment of ARDS induced by H1N1 influenza in 2009.
