【摘要】 肺萎陷是围手术期最常见的肺部并发症之一，它不仅增加低氧血症发生的风险，还会形成其他肺部并发症的病理生理学基础。作为围手术期肺保护的重要举措，肺保护性通气策略(LPVS)在预防肺萎陷、改善患者预后中起着重要的作用，其策略主要包括小潮气量、个体化适度呼气末正压、间断肺复张和低吸入氧浓度。本文就LPVS在预防肺萎陷的研究进展做一综述，为临床实践提供参考依据。更多还原

【Abstract】 Pulmonary collapse is one of the most common pulmonary complications during perioperative period.It not only increases the risk of hypoxemia,but also forms the pathophysiological basis of other pulmonary complications.As an important measure of perioperative lung protection,lung protective ventilation strategy (LPVS) plays an important role in preventing lung collapse and improving the prognosis of patients.Its strategies mainly include low tidal volume,individualized moderate positive end expiratory pressure,intermittent lung recruitment and low inhaled oxygen concentration.This paper reviews the research progress of LPVS in preventing lung collapse,so as to provide reference for clinical practice.更多还原
