Abstract

We report experimental evidence of light-induced changes in the transmission spectrum of human venous blood under the action of low-intensity radiation from He-Ne laser. We have applied a sensitive registration technique and the transmission spectra of diluted and nondiluted heparinized human venous blood have been analyzed before, after and in the course of irradiation. When irradiating nondiluted blood, reproducible variations of the blood transmission spectrum in the range of 640 - 805 nm have been observed for the first time. We found these changes correlate with oxygen saturation. The changes in transmission spectra and oxygen saturation of venous blood after 1-3 procedures of irradiation can be used as a method to detect an individual sensitivity to intravenous laser irradiation.
