是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

不公开/Private

盲法:

研究过程采用双盲法,由独立麻醉医师开封并设置氧流量,操作者、患者及观察者均不知分组信息;HFNC流量显示屏遮挡,仅显示“模式A/B/C”。由同一名呼吸内科医师进行气管镜诊疗相关操作。另一名有经验的麻醉医师作为盲态观察者负责麻醉维持、监护术中生命体征,保证合适的镇静深度并记录患者基本信息、气管镜检查具体操作,以及检查过程中的各项观察指标、不良反应发生情况。

Blinding:

The study was performed in a double-blind manner, and the oxygen flow rate was set by an independent anesthesiologist. The operator, patients and observers were unaware of the group information. The HFNC flow display is occluded and only "Mode A/B/C" is displayed. Bronchoscopy was performed by the same respiratory physician. Another experienced anesthesiologist, as a blind observer, was responsible for the maintenance of anesthesia, monitoring intraoperative vital signs, ensuring the appropriate depth of sedation, and recording the basic information of patients, the specific operation of bronchoscopy, and the observation indicators and adverse reactions during the examination.
