In the present study, we investigated the psycho-sensorimotor abilities of divers exposed to 6 ATA (50 m of sea water; corresponding to legal limit for occupational diving in North America, United Kingdom, and Northern Europe), or 7 ATA (60 m; the legal limit in France and Southern Europe) of compressed air (1 ATA = 100,000 Pa), using psychometric tests of manual dexterity, visual choice reaction time, and number ordination. The results of the present study showed that abilities in these tests were not significantly altered by pressure exposure to 6 ATA of compressed air. However, data obtained at 7 ATA showed slight but significant decreases in performance. Nevertheless, a few subjects presented large decreases in performance ranging from -20% to -25% of control. Finally, our results supported the ergonomic point of view that the laws limiting occupational diving to 6 ATA (50 m) are better adapted to reality and the requirements of underwater activity.
在本研究中,我们利用手动灵巧性、视觉选择反应时间和数字排序的心理测量测试,调查了暴露于6个绝对大气压(50米海水深度;相当于北美、英国和北欧职业潜水的法定极限)或7个绝对大气压(60米;法国和南欧的法定极限)压缩空气(1个绝对大气压 = 100,000帕斯卡)下的潜水员的心理感觉运动能力。本研究结果表明,这些测试中的能力在暴露于6个绝对大气压的压缩空气压力下并未显著改变。然而,在7个绝对大气压下获得的数据显示,表现略有但显著下降。尽管如此,一些受试者的表现大幅下降,幅度在对照的-20%至-25%之间。最后,我们的结果支持了人体工程学观点,即将职业潜水限制在6个绝对大气压(50米)的法律更符合实际情况和水下活动的要求。
