采用直接法测试最大摄氧量(Vo_2max)评价心肺功能,用WHO—NCTB评价作业工效。结果表明:移居者空运进入3680m高原后,早期体力下降明显,Vo_2max下降23％,经7～15月适应后,体力可逐步恢复,达到稳定,但Vo_2max仍比平原值低7.97％。4350m移居者各项指标均较3680m移居者低,7月后已达稳定,但Vo_2max比平原下降21％。低氧时3689m移居者作业工效的影响,表现在反应速度变慢,工效下降,而4350m移居者已开始累及记忆功能,提示低氧的蓄积效应。
The maximum oxygen uptake (Vo_2max) was measured by direct method to evaluate the cardiopulmonary function, and the work efficiency was evaluated by WHO-NCTB. The results showed that after 3600m altitude, the settlers dropped significantly and the Vo_2max decreased by 23%. After being acclimated for 7-15 months, the physical strength gradually recovered and reached a stable level, but Vo_2max was still 7.97% lower than that of the plain. The indicators for the 4350m settlers were all lower than the 3680m settlers and reached a stable level after July, but Vo_2max was 21% lower than that of the plain. Hypobaric 3689m migrant workers ergonomics, the performance slowed down the reaction, work efficiency decreased, and 4350m settlers have begun to affect memory function, suggesting that the accumulation of hypoxia effect.
