摘要
目的探讨高原驻训对飞行员急性缺氧耐力的影响,为航空卫生保障提供依据方法对18名参加高原驻训3个月,初下高原1周的高性能战斗机飞行员(驻训组)和36名未参加驻训的同机种飞行员(对照组)进行抗荷抗缺氧训练。以缺氧体验训练合格线2min为界,每20s记录1次飞行员的动脉血氧饱和度(arterial oxygen saturation,SaO_(2))和心率。运用飞行员抗荷抗缺氧能力检测仪、BeneView T6型心电监护仪进行训练、评估和监测。结果随着缺氧时间的延长,从缺氧体验训练60s开始,在相应的时间节点上,驻训组飞行员SaO_(2)均显著高于对照组,差异有统计学意义(t=2.63、3.32、4.79、4.32,P=0.011、0.002、<0.001、<0.001)。对照组飞行员的平均SaO_(2)随缺氧时间延长下降迅速,而驻训组随缺氧时间延长下降缓慢;驻训组飞行员的平均有效意识时间为(441.11±67.03)s,显著长于对照组的(195.00±31.49)s,是对照组的2.26倍,差异有统计学意义(t=17.74,P<0.001)。结论高原驻训后高性能战斗机飞行员急性缺氧状态下的SaO_(2)和有效意识时间得到显著提高。短期的慢性缺氧过程能显著提高飞行员的急性缺氧耐力,以利于有效应对高空缺氧。
Objective To provide references for aeromedical support by investigating the effect of training at high altitude on acute hypoxia tolerance of pilots.Methods Eighteen high performance fighter pilots who had returned to plain for 1 week as they finished 3-month residence in plateau were chosen as training group and 36 pilots who flied same aircraft type but without plateau stay and training were assigned as control group.Both groups received anti-G and anti-hypoxia training.The acceptance line of hypoxia experience training was defined to 2 min and the arterial oxygen saturation(SaO_(2))and the heart rate of pilots were tested every 20 s.The anti-G and anti-hypoxia ability detector of pilots and BeneView T6 ECG monitor were used for training,assessment and monitoring.Results SaO,level in the training group was significantly higher than that in the control group at the corresponding time point from the 60 s of the training,and the differences was statistically significant(t=2.63,3.32,4.79,4.32,P=0.011,0.002,<0.001,<0.001).The average of SaO_(2)in the control group decreased rapidly with the extension of hypoxia time,while the average of SaO_(2)in the training group decreased slowly with the extension of hypoxia time.The average of effective consciousness time of the training group[(441.1167.03)s]was significantly longer than that of the control group[(195.00±31.49)s],and was 2.26 times of the control group,the difference was statistically significant(t=17.74,P<0.001).Conclusions After stationed and trained in plateau,the SaO_(2)and the effective consciousness time of high performance fighter pilots under acute hypoxia have been significantly improved.Short term chronic hypoxia process can significantly improve the acute hypoxia tolerance of pilots,which is conducive to the effective response to high aerial hypoxia.
