早在1897年指示剂稀释法已用于心排出量的测定。指示剂包括染料、放射性示综物、温热(温盐水或冷盐水)等。最早使用的指示剂是染料。60年代中期,我国已开始进行染料稀释法的研究。十余年来,由于药品工业和电子仪器工业的发展,染料稀释法已大为改进,可以直接由电子计算机报告计算结果。目前最常用的染料是心绿。它毒性小,对心血管系统无副作用,能迅速排泄,因而在短时间内可重复注射。本文报
As early as 1897, the indicator dilution method has been used for the determination of cardiac output. Indicators include dyes, radioactive compounds, warm (warm salt water or cold salt water) and so on. The earliest used indicator is dye. In the mid-1960s, China has begun to study the dye dilution method. More than ten years, due to the development of pharmaceutical industry and electronic instrument industry, the dye dilution method has been greatly improved, and the calculation results can be directly reported by electronic computers. The most commonly used dye is heart green. It is less toxic, has no side effects on the cardiovascular system and can be excreted rapidly, allowing repeatable injections within a short period of time. This article reported
