Paper Abstract

The influence of low-intensity laser radiation on the transport of human blood within skin capillaries is investigated in vivo on cardiac ischemia patients. For the sample as a whole the mean blood perfusion increased by thirty percent after exposure, for 10 minutes, to light from a Helium Neon laser at an irradiance level of 225 W/m2. In some individual patients the blood perfusion more than doubled. A two-dimensional theoretical model is developed that suggests that modest heating of the blood is induced by the incident radiation and could be responsible for the observed increase.
