不同程度急性缺氧对皮肤微循环的影响

The changes of microcirculation in cheek and calf of 12 subjects were recorded during simulated 3 000 m, 4 000 m, 5 500 m anoxia. The result showed that the blood volume and cocentration of cheek was decreased gradually with the increased degree of anoxia. The changes of velocity of flow in cheek were less. The effect of different acute anoxia on skin microcirculation of calf was less. The result suggests that the skin microcirculation of face involve in regulate of brain circulation during acute anoxia.
