研究目的:

1.观察固定PEEP和个性化PEEP在肥胖患者减重手术中对肺功能的影响作用。 2.调查麻醉期间肥胖患者适宜的呼气末正压水平,为减重代谢手术的麻醉呼吸精细化管理提供科学可靠的依据,并科学的完善肺保护通气策略。  

Objectives of Study:

1.?Observing the effects of fixed positive end-expiratory pressure (PEEP) and individualized PEEP on pulmonary function in obese patients undergoing bariatric surgery. 2.?Investigating the appropriate level of PEEP during anesthesia in obese patients, providing a scientific and reliable basis for the refined management of anesthesia and respiration in bariatric surgery, and scientifically improving the lung protective ventilation strategy.

指标类型:

主要指标

Outcome:

lung ultrasound score

Type:

Primary indicator

测量时间点:
