Study on the effect of altitude hypoxia environment on cardiopulmonary function of working miners
-
摘要: 为促进高原地区矿工心肺功能及身体健康,本文综合利用问卷调查法、数理统计法、对比分析法等科学方法,对西藏华泰龙(高海拔地区)和河北开滦(低海拔)两地的健康矿工进行心肺功能检测,从通气指标、代谢指标和心率变异性指标3个维度对检验结果进行研究对比和统计分析。研究结果表明,高原矿工在通气、代谢及心率变异性指标3个层面均与平原作业矿工存在显著差异,且各项指标表明高原矿工的心肺功能均要显著弱于平原矿工。基于以上研究结果,提出改善高原矿工心肺功能的针对性建议。本研究对改善高原作业矿工身体健康有一定的参考价值和借鉴意义。Abstract: In order to promote the cardiopulmonary function and health of miners in plateau areas, this paper uses scientific methods such as questionnaire survey, mathematical statistics and comparative analysis to test the cardiopulmonary function of healthy adult miners in Chian Tyrone, Tibet (high altitude area) and Kailuan, Hebei(low altitude area), and studies the test results from three dimensions of ventilation index, metabolic index and heart rate variability index.The results showed that there were significant differences in ventilation index, metabolism index and heart rate variability index between the plateau miners and the plain miners, and the indexes showed that the cardiopulmonary function of the plateau miners was significantly weaker than that of the plain miners.Based on the above research results, some suggestions were put forward to improve the cardiopulmonary function of plateau miners.This research has certain reference value and significance for improving the health of miners working on plateaus.
