Paper Abstract

One of the mechanisms of influence of laser radiation on the biological tissue is photodissociation of oxyhemoglobin with releasing of molecular oxygen, thus decreasing the degree of blood oxygen saturation. The experimental study of oxygen saturation of arterial blood under laser action is based on the registration of small variations of the saturation value on the background of the natural saturation oscillations. While the determination of the value of oxygen saturation allows to observe respiratory processes, the value of venous saturation allows to determine the dynamics and efficiency of the oxygen absorption in tissues, as well as the condition of venous vessels. The tissue and vein oxygen saturation have not been studied sufficiently so far. The simlutaneous control of arterial and tissue saturation values will give opportunity to study the oxygen supply processes. The aims of this work are experimental study of laser induced photodissociation of oxyhemoglobin and determination of the dependence between the saturation value and the laser parameters. This will allow to develop new methods of control, as well as to realized a feedback during laser therapy.
