Each subject had passed a standard oxygen tolerance test prior to the beginning of diving training and became familiar with experimentalkcientific hyperbaric exposition. Each of them was experienced in the use of closed -circuit oxygen rebreathing apparatus type Oxy-NG (oxygen set produced by La Spirotechnique - Nice). Their main physiological data are shown in Figure 1. Twenty-seven expe
