【Abstract】 From 1996,a new mechanical ventilation mode has been used in patients with ARDS.The result was satisfactory.In our practice,muscle-paralising drugswere used to had the respiratory muscles paralised and this will elimilate the phynomenon of patient-anti-ventilator,so ventilation in lung was amelioated.PEEP was also used to lift the functional residual volume of gas in lung and to improve the compliance of lung.This will prevent the lung from collapsing\,lessen the effusion in mesenchyma of lung and improve gas exchange Bronchodilator was used to lessen spasm of smooth muscle in bronchi and to lower air-way resistance.Then ventilation will also be amelioated.The above procedures can lessen the dead cavity in lung\,improve ventilation/blood ratio\,rapidly lift the Po2.The time requiring mechanical assistance in patients with ARDS was shortened considerably.The mortality of patients was lowered considerably.更多还原
