Abstract
[ Abstract ] Objective To simulate the push - pull - like effects of physiological reaction to hypoxia, viz. The human physiological reaction when the environment is rapidly switched from high oxygen partial pressure to low oxygen partial pressure. Methods Six young male volunteers underwent two kinds of environments, I. E. They were switched from the normal pressure and normoxia condition and the normal pressure and 50% high oxygen partial pressure condition to the low oxygen partial pressure condition ( 12.9% ,simulation of 4 km above the sea level ), respectively. Afterwards, all volunteers sat silently for 30 min. During the whole process, the physiological parameters of these volunteers, such as saturation of blood oxygen, heart rate and respiratory wave, etc, were continuously measured. Results ( 1 ) Compared with the condition switched from normoxia to hypoxia, the decrease range of the volunteers'SpO2 was more obvious when the environment was switched from hyperxia to hypoxia. ( 2 ) The changing time of oxygen partial pressure was 2 min. ( 3 ) There were significant individual differences in the volunteers' reaction patterns and tendency of physiological parameters. Conclusion The self - designed normal - pressure and hypoxia cabin is feasible. The push - pull - like effects of physiological reaction to hypoxia are simulated preliminarily and some valuable physiological parameters are observed, which provides basic data for further research and alleviating the adverse influence caused by push - pull - like effects on flying personnel.关键词
