Inside open water and particular during professional or recreational diving the individuum is additionally burdened by significant changes in the ambient physical conditions, which heavily influence the human physiology.

Changes in the partial pressures of breathing gases during diving may gain significant influence on physiological processes to the point of toxic effects of under normal pressure harmless gases. A particular focus is set here on hyperoxia, hypercapnia and the narcotic effects of nitrogen.

Furthermore, darkness, coldness and extreme ambient conditions can have a severe impact on the diver´s mind, thus possibly leading to erroneous reactions in an emergency situation.
