摘　　要：本文通过对9名高原红细胞增多症患者分别在西宁(2260米)和苏州(10米)进行了静息和运动状态下有关心肺功能参数自身对比观察。发现与在西宁相比,患者在苏州静息状态下每分通气量不降低,而心率减慢、氧耗量降低,氧当量增高;在相同负荷运动中通气量低,心率慢、氧耗量和代谢量单位等都低,而AT值(无氧代谢阈值)增高。提示高原红细胞增多症患者进入平原后运动耐力增加,心肺功能有所改善。The self—comparative observations were done in 9 patients with polycythemia under the conditions of rest and exercise in Xining (2260 meter)and Suzhou(10 meter) respectively. It was found that ventilation volume per minute was not reduced in these patients at rest in Suzhou. But beart rate and oxygen comsumption were reduced and oxygen equivalent increased, on exercise with the same load ventilation volume decreased and heart rate slowed. So did oxygen comsumption and metabolism rate. On the contrary anaerobic threshold(AT)incerased. It is indicated that the patients with polycythemia gain exercise capacity after the arrival of plain and careiac and pulmonary functions are improved.
