摘要
国内首次302m氦氧饱和潜水模拟实验中,用心理学测验和主观感觉询问对3名受试者的神经和心理反应现象进行了观察。加压到200m、250m、302m和302m停留1天后,受试者的简单视觉运动反应时较常压对照值分别延长了7.3%、4.5%、6.5%和6.1%。加压到200m受试者书面心理学测验失分率较常压对照值增加了156.4%。加压到250m受试者滚珠投递数和失误数较常压对照值分别减少12.2%和增加27.6%。302m停留1天后受试者滚珠投递数和失误数较常压对照值分别减少11.3%和增加56.2%,扑克花样分类时间较常压对照值增加8.7%,书面心理学测验失分率较常压对照值增加113.8%。减压后或减压毕,上述各指标的变化均恢复常压对照水平。根据测试结果和受试者的症状和体征,实验中所观察到的高压神经综合症的表现较国外同样深度的实验报道为轻,这可能与实验采用的缓慢加压速度和设置中间驻留站有关。
During the simulated heliox saturation dive at the depth of 302 m.,some neurophysiological and psychological functions of the 3 subjectswere observed through the senses of the subjects and psychological tests.The results showed that simple visual reaction-time was prolonged by7.3%, 4.5% and 6.5% during the compression from surface to 200m, 250mand 302m respectively. The error ratio of mental test in book-answerway increased by 156.4% at the interim stop of 200m. During compressionto 250m, the ballbearing rate decreased by 12.2% and the error ratioincreased by 27.6%. After staying at 302m. for 1 day, the simple visualreaction-time was prolonged by 6.1%, the ballbearing rate decreased by11.3% and the error ratio increased by 56.2%, the sorting card timewas prolonged by 8.7% and the error ratio of mental test in book-answerway increased by 113.8%. All the changes mentioned above returned tothe control levels after the beginning of decompression or reaching thesurface. The symptoms of HPNS of the subjects were light, which mightbe related to the slow compression rate and interim stops.
