求翻译：吸痰是保持呼吸道通常，预防肺部感染的重要措施，临床常用开放式气管内吸痰（open endotracheal suctioning,OS）， 吸痰过程中需脱离呼吸机， 对正在进行高浓度吸氧、机械通气的急性肺损伤动物可导致低氧血症。密闭式气管内吸痰(closed endortacheal suctioning,CS)过程中不需要脱离呼吸机，可以保持吸痰时的通气及吸入氧浓度（FiO2）不被污染，避免了交叉感染，能减少并发症，提高抢救成功率，降低患者死亡率，提高患者生存质量。是什么意思？

Suction is to keep the respiratory tract is usually the prevention of pulmonary infection, commonly used in clinical open endotracheal suctioning (the open of endotracheal suctioning, os), the suction process required from the ventilator, ongoing high concentrations of oxygen, mechanical ventilation

The process is to maintain respiratory tract is usually to prevent lung infections of the important measures, clinical commonly used in open-air suction catheter (Open endotracheal suctioning, OS) and the process required in the process, from breathing to the ongoing high-density oxygen and mechanic

Maintain respiratory suctioning is usually important measures for prevention of pulmonary infection, commonly used clinical open endotracheal suctioning (open endotracheal suctioning,OS), be out of breath in the suction process, high concentrations of oxygen and mechanical ventilation in acute lung
