Ukrainian Journal of Physics| Summary: | The work is devoted to the determination of the external transcutaneous laser radiation effect on the relative concentration of oxyhemoglobin in venous blood. It is shown that transcutaneous laser irradiation of biological blood-filled tissue changes the venous blood oxygen saturation value only if a certain level of laser-stimulated photodissociation of oxyhemoglobin in arterial blood is reached (more than 6% decrease of the arterial blood oxygen saturation value). From our point of view, this process is not a direct laser-stimulated photodissociation of oxyhemoglobin in venous blood, because the dissociation curve is situated in the region with high values of partial oxygen pressure. The decrease in the relative concentration of oxyhemoglobin in venous blood is most likely related to compensatory mechanisms of hypoxia in peripheral tissues, accounting for the recombination of oxyhemoglobin molecules during their passage from the point of irradiation to the point of oxygen extraction by cells. |
