Objective to observe the effect of pulmonary surfactant on lung gas exchange and oxygenation index in the patients with acute respiratory distress syndrome (ARDS).
目的观察肺泡表面活性物质对急性呼吸窘迫综合征(ARDS)患者通气、氧合功能的影响。
Results: Standardization regression coefficient from big to small in proper order were: oxygenation index, CT, body temperature of the admission day, BMI were the most influence on ALI;
结果：按标准化回归系数绝对值由大到小：氧合指数、CT、入院体温、体质量指数对ALI的影响最大；
Near-infrared spectroscopy (NIRS) was used to continuously monitor the cerebral tissue oxygenation index (TOI) percutaneously.
术中应用近红外分光光谱仪（NIRS）经皮连续监测脑组织氧合指数（TOI）变化。
