We determined cardiac output and blood volume by measuring indocyanine green(ICG) concentration by using near infrared spectroscopy(NIRS). 0. 8ml of ICG was enough to measure ICG concentration when we set the probe on the forehead. However, the concentration of ICG among each subjects showed a wide difference that it was not accurate as cardiac output measured by impedance cardiography or blood volume measured by Evans blue dye dilution method.

采用近红外光谱法测定吲哚菁绿（ICG）浓度，测定心排血量和血容量。0. 将探头置于额头上，8ml ICG足以测量ICG浓度。但各受试者间ICG浓度差异较大，与阻抗心动图测心输出量或Evans蓝染稀释法测血容量不一致。
