The concentration of carbon dioxide in end-tidal gas was compared with the tension in arterial or superior vena caval blood during thoracotomy in twelve patients. In six adults requiring pulmonary resection, one-lung anaesthesia did not change the difference between the two measurements. In six children in whom a systemic to pulmonary arterial anastomosis was being created to improve pulmonary blood flow impaired by cyanotic congenital heart disease, occlusion of the pulmonary artery caused in increase in the blood-end-tidal carbon dioxide gradient. This change was particularly marked in two neonates and was of sufficient magnitude to render end-tidal monitoring unreliable in these circumstances.
在12例患者开胸手术期间，对终末潮气二氧化碳浓度与动脉血或上腔静脉血中的张力进行了比较。在6例需要肺切除的成人患者中，单肺麻醉并未改变这两种测量值之间的差异。在6例因青紫型先天性心脏病导致肺血流受损而进行体肺分流术以改善肺血流的儿童中，肺动脉阻断导致血-终末潮气二氧化碳梯度增加。这种变化在2例新生儿中尤为明显，其幅度足以使在这些情况下终末潮气监测不可靠。
