The present invention includes a detector that detects the spectrum of a blood volume indicator, an intravenous probe for insertion into a blood vessel of interest, an optical fiber that connects a detector (spectrophotometer or photodetector) to the intravenous probe, and blood. Determine total circulating blood volume (BY) using a blood volume determination device with a light source (wide spectrum light source, laser diode, LED) to illuminate the volume indicator and minimally invasive techniques. Disclose the method and system. [Selection diagram] Fig. 1 |
