目的:了解和掌握南极内陆不同海拔环境对考察队员心肺功能相关指标的影响,为南极冰穹A考察医疗保障提供科学依据。方法:16名考察队员行进至海拔2 000m、2 500m、3 000m、3 500m、4 087m(冰穹A)等不同海拔的南极内陆高原时,严密观察和详细记录呼吸、心率、血压、血氧饱和度变化和高原反应问卷。结果:随着海拔梯度的升高,各组间心率、呼吸及血氧饱和度有明显的差异变化,且存在显著差异(分别为P<0.01,P<0.05,P<0.01)。而且2 500m以上海拔组与2 000m组在心率、呼吸及血氧饱和度存在显著变化,血压在各组间无显著性变化。结论:昆仑站考察队员在不同高海拔缺氧程度下所致的心肺功能相关指标有显著的差异性,这对预防和治疗南极高海拔低氧环境下高原病有积极的指导作用。
OBJECTIVE: To understand and grasp the influence of different altitude environment in Antarctica on the indexes related to cardiopulmonary function of expedition members, and to provide a scientific basis for the medical insurance of Antarctic Dome A. Methods: Twenty-six expedition members closely monitored and recorded respiratory, heart rate, blood pressure and blood levels in the Antarctic inland plateau at altitudes of 2 000 m, 2 500 m, 3 000 m, 3 500 m, and 4 087 m (Dome A) Oxygen saturation changes and altitude sickness questionnaire. Results: There was a significant difference in heart rate, respiration and oxygen saturation (P <0.01, P <0.05, P <0.01, respectively) as the altitude gradient increased. In addition, there was a significant change in heart rate, respiration and oxygen saturation at 2 500 m above sea level and 2 000 m group, with no significant changes in blood pressure among the groups. Conclusion: There are significant differences in cardiopulmonary function index between Kunlun station expeditioners at different altitude hypoxia, which has a positive effect on the prevention and treatment of altitude sickness in Antarctic high altitude hypoxia environment.
