The endotracheal tube and bronchial blocker combination is an accepted lung isolation technique used during thoracic surgery. A reliable and inexpensive method of confirming lung isolation that uses capnographic monitoring of the bronchial blocker central lumen is presented. As the bronchial blocker balloon is inflated, lung isolation is confirmed when the normal respiratory variation of carbon dioxide (CO(2)) is replaced by a persistent plateau CO(2) waveform.
气管内导管和支气管封堵器联合使用是胸外科中一种公认的肺隔离技术。本文提出了一种可靠且经济的方法，通过监测支气管封堵器中央管腔的二氧化碳（CO2）呼末变化来确认肺隔离。当支气管封堵器气囊充气时，正常的呼吸性 CO2 变化被持续的平台型 CO2 波形所取代，即可确认肺隔离。
