Conditions
Interventions
Artificial Intelligence Group:The physical matching criterion of the DLB model is that the outer diameter of the anterior end of the bronchial lumen is 1~2mm smaller than the patients left bronchial i
Traditional Experience Group:For female patients, 1.52 Fr for models with a height of 1.60 m
For male patients, 1.60 m 1.70 m tall model is 41 Fr. Since there is no 41Fr left DLT in our hospital, the maximum model of left DLT in this study is 39 Fr.
