利用减压舱观察了模拟不同海拔高度急性低氧对大鼠行为的影响。结果表明，随海拔高度升高，缺氧程度加深，大鼠进食量明显减少、活动减少，对敲击舱壁的声音刺激反应减弱，呼吸困难及发纶程度加重。表明缺氧引起中枢神经系统功能活动抑制，进而发展为意识障碍。 The effects of acute hypoxia at different altitudes on the behavior of rats were observed by using decompression cabin. The results showed that as the altitude increased, the degree of hypoxia deepened, the food intake of rats decreased significantly, the activity decreased, the percussion bulkhead sound stimulation reaction weakened, dyspnea and aggravate the degree of aggravate. Hypoxia caused central nervous system functional activity inhibition, and then developed into disturbance of consciousness.
