研究目的:

本研究的目的是观察肺复张后使用不同水平的 PEEP 对肺顺应性恢复到基线水平的时间及对全身麻醉期间患者氧合、通气、肺力学参数和血流动力学指标的影响程度。  

Objectives of Study:

The aim of this study was to observe the time to return to baseline level of pulmonary compliance and the extent of effect on oxygenation, ventilation, pulmonary mechanical parameters and hemodynamic indices of patients during general anesthesia by using different levels of PEEP after pulmonary recruitment maneuvre.
