THE PROCEDURE BY EVALUATION OF DIVERS FOR THE DEEP DIVING

Abstract

When a diver is selected to perform a deep diving course, he has to pass a medical test and isn’t affected by the HPNS (High Pressure Nervous Syndrome). When a diver is selected to perform a deep diving course, he has to pass an evaluation stage in order to prove his ability to tolerate the compression speed accompanied by the helium - oxygen breathing mixture without encountering the HPNS effects. The deep diving test consists in postural tremor and the EEG registration, in both conditions: at the atmospheric pressure and at 180 m deep too. Then the results obtained at the surface percentage limits are fixed for the maximum deflection agreed between the values registration made under pressure and the atmospheric pressure (surface) values.
