Cohort study 

研究目的:

本研究旨在通过回顾性观察分析,比较不同流量鼻高流量氧疗在ERCP镇静患者中的氧合效果及相关临床结局,为优化ERCP围术期氧疗策略提供临床依据。首要结局:进镜时的最低指脉氧饱和度SpO2; 次要结局:1)亚临床低氧血症(SpO? 90%–94%)/低氧血症(SpO? < 90%)的发生率,2)动脉血气指标变化,3)气道干预发生率,4)医患满意度评价  

Objectives of Study:

Primary Objective: To compare perioperative oxygenation among different oxygen therapies, assessed by the lowest peripheral oxygen saturation (SpO?) recorded during the procedure. Secondary Objectives:To compare the incidence of subclinical hypoxemia (SpO? 90–94%) and hypoxemia (SpO? < 90%) To evaluate arterial blood gas parameters (PaO?, PaCO?) To compare the incidence of airway interventions To assess patient and operator satisfaction
