This report presents a new, simple and reliable method of quantitating left-to-right shunts from arterial dilution surves. When indicatior (e,g., indocyanine green) is injected centrally (right venticle or pulmonary artery) and blood is withdrawn rapidly from either the aorta or other central systemic artery, in the presence of a left-to-right shunt to recorded indicator-dilution curve usually shows two discrete peaks: p-1 of the magnitude of the shunt expressed as percent of pulmonary blood flow, Experimental and clinical data demonstrate that this method is accurate in quantitating shunts from such curves.
本报告提出了一种新的、简单且可靠的方法，用于从动脉稀释曲线定量左向右分流。当指示剂（如吲哚菁绿）经中心部位（右心室或肺动脉）注入，且在存在左向右分流的情况下，从主动脉或其他中心体动脉快速抽血时，所记录的指示剂稀释曲线通常显示两个离散的峰：P-1，分流大小以肺血流量的百分比表示。实验和临床数据表明，该方法可准确地从此类曲线定量分流。
