[Problems in the deep: the isopression phase].
Fundamentally, accident mechanisms during the isopression phase of diving are primarily dependent upon the partial pressures of the respiratory gases. An increased nitrogen partial pressure leads to compressed-air intoxication; an increased oxygen partial pressure while diving with oxygen-enriched gas mixtures can trigger an oxygen-induced convulsion. Elevated pCO2 can be provoked by inadequate breathing and/or physical exertion at greater diving depths. Through an adjusted diving behavior and observation of the limits, these problems could be easily avoided.
