[Intravenous laser irradiation of blood and oxygen transport function]

The oxygen-transporting function of the blood was assessed in children with acute respiratory failure before and after laser irradiation of the blood. The microcirculatory component of transport was assessed by transcutaneous oxygen monitoring using functional tests, the hemic component by assessment of the gaseous composition of arterial blood and estimation of oxygenation algorithm. Four variants of tissue hypoxia were revealed in the examinees. Laser exposure had a good effect on the mechanisms leading to two types of hypoxia, hypoxic and ischemic.
