[Effect of cyclic hypoxia-hypercapnia on microcirculatory blood flow in healthy servicemen].
To evaluate how the training on hypoxia-hypercapnia combined effect (HHCE) influences the microcirculatory state 25 healthy servicemen were examined who underwent 20-day HHCE cycles--30-minute breathing, O2 - 12%, CO2 - 4%. It was established that during HHCE compared with atmospheric aie breathing the microcirculatory blood flow increases on the average by 35%. During training the microcirculatory reactivity in response to HHCE progressively increases. The gradual intensification of microcirculation in normal breathing conditions was noted.
