Abstract

A rapid, simple and low-cost method is presented for intracardiac left-to-right shunt quantification in children with congenital heart disease. The percentage of shunt is calculated from data obtained by continuous PO2 measurement during oxygen inhalation, using a nondisposable intravascular PO2-electrode cardiac catheter. These values are compared with those obtained by the dye-dilution method (correlation coefficient r = 0.89) and the Fick method (correlation coefficient r = 0.98). The PO2 measurement proved reliable for small, medium, and large sized shunts.

摘要

本文介绍了一种快速、简单且低成本的方法，用于定量评估先天性心脏病患儿的心内左向右分流。分流百分比通过使用一次性血管内PO2电极心脏导管在吸氧期间连续测量PO2获得的数据来计算。将这些值与通过染料稀释法（相关系数r = 0.89）和菲克法（相关系数r = 0.98）获得的值进行比较。结果证明，PO2测量对于小、中、大型分流均可靠。
