After reports of carbon monoxide toxicity from the United States, the Medicines Control Agency issued a warning which recommended that soda lime used in circle breathing systems should not be allowed to dry out. We have measured carbon monoxide levels within a circle system in vitro (under a variety of conditions) and in vivo. Carbon monoxide was detected only when a patient was connected to the circle system. As levels in the expiratory limb of the circle system were significantly higher than those in the inspiratory limb, we conclude that the patient acts as the source of carbon monoxide.
在美国有一氧化碳中毒的报告后，药品控制局发布了一项警告，建议循环呼吸系统中使用的苏打石灰不应变干。我们已经在体外（在各种条件下）和体内测量了循环系统内的一氧化碳水平。仅当患者连接到循环系统时才检测到一氧化碳。由于循环系统呼气支路中的水平明显高于吸气支路中的水平，我们得出结论，患者是一氧化碳的来源。
