Decompression Sickness: Cerebral Arterial Gas Embolism

Although recompression treatment of CAGE traditionally involved a deep excursion to 50 metres followed by a standard USN Table 6, diving physicians now use a standard 18-metre oxygen table such as USN Table 6.
If the CAGE is not caused by DCS and is a manifestation of pulmonary barotrauma,

then the following other factors should be considered:

  • The possibility of little or no inert gas loading in the tissues (thus making long saturation type treatments inappropriate and brief deep excursions more valuable).
  • The presence of pulmonary tissue damage.
  • The possibility of pneumothorax.
  • Fitness for further diving and its investigations.
