Abstract:

In order to determine the safe depths at which divers can live while breathing air, a battery of medical, physiological, and performance tests were administered to subjects who lived for a month in the NavSubMedRschLab pressure chamber at 50 ft and at 60 ft. The tests included a number of measures of visual physiology and visual performance, since many of the symptoms of oxygen toxicity involve the visual system. The results showed no decrements in visual acuity or in the size of the field of view at either 50 ft or 60 ft. There were no abnormal changes in the EEG during saturation, and the only changes in the visual evoked response occurred during excursions from the saturated depth.
