Using capnographic changes to assess pulmonary perfusion impairment during pulmonary surgery: animal experiments and clinical studies.
A distinctive capnography pattern may signal reduced blood flow during lung surgery, enabling real-time monitoring.
This study first reported a characteristic "chair-back" capnogram with an alpha angle less than 90 degrees during sleeve lobectomy, suggesting impaired pulmonary artery perfusion, in both animal experiments and clinical cases. When interpreted together with decreases in PetCO2 and increases in the Pa-etCO2 gradient, the "chair-back" capnogram may serve as a potential real-time capnographic sign of pulmonary perfusion impairment when a double-lumen tube is used during pulmonary surgery.
