摘要

A 68-year-old presented for pulmonary lobectomy under one lung anesthesia. It is essential to determine if the remaining parenchyma is adequate for ventilation. The DLCO can predict that. The technique of placing a double-lumen tube with a fiberoptic bronchoscope serving as a stylet must be precise. There are two basic scenarios for intraoperative hypoxia. Hypoxic pulmonary vasoconstriction (HPV) is not operant in the upper lung or is operant in the dependent lung. Exact placement of the double-lumen tube enables the implementation of CPAP or PEEP to treat hypoxia.
