Dye dilution method

Japanese: 色素希釈法 - しきそきしゃくほう（英語表記）dye dilution method

A method for examining circulatory dynamics. A dye is injected rapidly once or continuously into the blood flowing through the blood vessels, and the state of blood flow is measured by continuously observing the process of changes downstream as the dye is diluted by the blood flow. The most commonly used method is the single rapid injection method, which is performed by using a peripheral vein in the arm as the injection site and a peripheral artery as the recording site, sandwiching the heart and pulmonary blood vessels. The dye used is indocyanine green, which is non-toxic and resistant to chemical and optical changes.

循環動態を検査する一方法。血管内を流れる血液に色素を1回急速注入または持続的に注入し，血流によって希釈される変化過程を下流で連続的に観察することによって，血液の流れの状態を測定しようとする方法である。最も多く用いられるのは1回急速注入法で，心臓，肺血管をはさんで注入部位を腕の末梢静脈，記録部位を末梢動脈として実施する。色素は毒性がなく，化学的，光学的な変化を受けにくいインドシアニングリーンが用いられる。
