Inclusion criteria

Inclusion criteria: 1. Patients scheduled for elective video-assisted thoracoscopic partial pulmonary resection under general anesthesia, with a body mass index (BMI) between 24 and 35 kg/m². 2. Age 18 to 75 years, irrespective of gender. 3. American Society of Anesthesiologists (ASA) physical status classification I-III. 4. Informed of and willing to participate in the trial, having provided written informed consent.

Exclusion criteria

Exclusion criteria: 1. Severe pulmonary diseases, such as chronic obstructive pulmonary disease (COPD) with a GOLD classification >2, severe asthma, or a history of pneumothorax, which may affect pulmonary compliance. 2. Severe cardiac (New York Heart Association [NYHA] class III or IV), hepatic (Child-Pugh score 10-15), renal (requiring renal replacement therapy), or hematopoietic system diseases (e.g., leukemia). 3. Conditions that make lung ultrasound difficult to perform (e.g., chest wall fracture, thoracic deformity). 4. History of previous pulmonary surgery. 5. History of upper respiratory tract infection within two weeks prior to surgery. 6. Participation in other clinical trials within the past three months.
