Capnography has been studied for decades as a potential diagnostic tool for suspected pulmonary embolism. Despite technological refinements and its combination with other non-invasive instruments, no evidence to date allows recommending the use of expired carbon dioxide measurement as a rule-out test for pulmonary embolism without additional radiological testing. Further investigations are, however, still warranted.
二氧化碳描记法作为疑似肺栓塞的潜在诊断工具已经研究了几十年。尽管技术得到了改进,并与其他非侵入性仪器相结合,但迄今为止没有证据表明可以推荐使用二氧化碳呼出量测量作为排除肺栓塞的常规检测手段,而无需进行额外的放射学检查。然而,仍需要进一步的研究。
