研究目的:

1.观察OLV期间实施驱动压指导的个体化潮气量是否可以降低超重/肥胖患者胸科手术术后肺不张发生率; 2.观察个体化潮气量策略是否可以提高超重/肥胖患者术中氧合指数。  

Objectives of Study:

1. To determine whether implementing driving pressure-guided individualized tidal volume during one-lung ventilation (OLV) reduces the incidence of postoperative atelectasis in overweight/obese patients undergoing thoracic surgery. 2. To investigate whether the individualized tidal volume strategy improves the intraoperative oxygenation index in overweight/obese patients.

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.
