Effect of Low Tidal Volume Ventilation in Improving Oxygenation and Thus Reducing Acute Lung Injury in the Cardiac Surgical Patient

acute respiratory distress syndrome, acute lung injury, cardiac surgery, the incidence of ards after elective cardiac surgery is 1-3%, the impairment of lung function and oxygenation may occur in 20-80% of patients undergoing surgery., the purpose of this study is to assess the efficacy of low tidal volume ventilation., reducing interleukin and cytokine production may prevent or reduce the incidence of acute lung injury., interventional, na
