中文摘要:

      目的氧疗是围术期麻醉管理的重要组成部分。氧疗是把双刃剑，氧浓度过高可产生肺不张、氧化应激，给机体造成损伤，过低又会导致低氧血症，影响氧合。因此，围术期氧疗如何选择合适的吸氧浓度一直是麻醉管理的热点问题。本文将围绕围术期氧疗对机体的影响、不同类型患者吸入氧浓度的选择作一综述，以期为围术期精准氧疗提供理论参考。

英文摘要:

      Oxygen therapy is an important part of perioperative anesthesia management. Oxygen therapy is a double-edged sword: too high oxygen concentration may result in atelectasis and oxidative stress damage, while too low can lead to hypoxemia and affect oxygenation. Therefore, it is a hot and difficult issue to choose the appropriate oxygen concentration perioperatively. This review will discuss the effects of perioperative oxygenation on the organism, the selection of inhalation oxygen concentration for different types of patients, in order to provide theoretical reference for perioperative precise oxygen therapy.
