A non-invasive technique of measuring cardiac output changes is described and studies of its accuracy and reproducibility are reviewed. Cardiac output changes in 11 patients undergoing Caesarean section under general anaesthesia were measured with this technique. Increases in cardiac output after induction and commencement of surgery (mean 19%, p less than 0.05), and after delivery (mean 19%, p less than 0.05) were found.
本文描述了一种测量心输出量变化的非侵入性技术，并综述了其准确性和可重复性的研究。使用该技术测量了11例接受全身麻醉下剖宫产手术患者的心输出量变化。结果发现，诱导麻醉和手术开始后（平均增加19%，p<0.05）以及分娩后（平均增加19%，p<0.05）心输出量均增加。
