摘要
目的比较适度海拔地区与低海拔地区人群的肺功能、血红蛋白、氧饱和度,分析适度海拔地区对人体肺功能的影响。方法收集并比较适度海拔地区、低海拔地区人群的肺功能、血红蛋白、氧饱和度,采用Pearson相关分析计算两个地区人群的年龄、身高、体质量与其肺功能参数之间的相关性。结果适度海拔地区人群的肺活量、用力肺活量、一秒用力呼气量、一秒率、最大呼气中期流量,与低海拔地区人群差异无统计学意义(P>0.05);适度海拔地区人群最大呼吸流量高于低海拔地区人群,差异有统计学意义(P<0.05)。Pearson相关分析显示:两个地区人群的肺功能均与年龄呈显著负相关;身高与用力肺活量、一秒用力呼气量、最大呼气中期流量均呈正相关,体质量与用力肺活量正相关;均P<0.05。适度海拔地区人群氧饱和度低于低海拔地区人群,适度海拔地区男性血红蛋白高于低海拔地区男性,差异均有统计学意义(P<0.05)。结论适度海拔地区人群氧饱和度降低,男性血红蛋白代偿性升高;适度海拔地区人群的呼吸阻力下降,最大呼气流量升高。
Objective To investigate and analyze the lung function,hemoglobin and oxygen saturation of people in moderate altitude area and low altitude area,and explore the effects of moderate altitude area on human lung function.Methods The data of lung function,hemoglobin and oxygen saturation were collected from moderate altitude areas and low altitude areas,and Pearson correlation analysis was performed to calculate the correlation between age,height and weight and lung function parameters in the two areas.Results There were no statistically significant differences in lung capacity,expiratory capacity,expiratory capacity in one second,one-second rate,and maximal mid-expiratory flow rate between the moderate altitude population and the low altitude population(P>0.05).However,the maximal respiratory flow rate of the moderate altitude population was significantly higher than that of the low altitude population(P<0.05).The Pearson correlation analysis revealed a significant negative correlation between age and lung function in both populations.Additionally,height was positively correlated with expiratory lung capacity,expiratory volume in one second,and maximum mid-expiratory flow rate,while body mass was positively correlated with expiratory lung capacity.All of these correlations were statistically significant(P<0.05).The study found that the oxygen saturation of individuals living in moderate altitude areas was lower than that of those living in low altitude areas,while the haemoglobin levels of individuals living in moderate altitude areas were higher than those of individuals living in low altitude areas.These differences were statistically significant(P<0.05).Conclusions In males from moderate altitude populations,there is a reduction in oxygen saturation and compensatory increases in haemoglobin.Moderate altitude,on the other hand,have reduced respiratory resistance and increased PEF.
