Nitrogen Narcosis and Performance Under Water

摘要: Abstract Eighteen divers were tested four times under water, twice at a depth of 5 ft and 100 ft. They performed three tests—digit copying, sentence comprehension test manual dexterity test. All showed significant drop in efficiency depth. This was small for digit copying (7-9 per cent) (3 5 cent), somewhat larger (15-3 cent). In all cases the approximately same as found equivalent pressure dry chamber. contrasts with previous results where impairment open sea has been considerably greater than Possible reasons this discrepancy are discussed it is suggested that level anxiety may be crucial factor.
