“Vascular bubbles formed as a result of DCS continue to grow for hours after their initial formation and mainly damage the endothelium with numerous secondary effects related to biochemical or immunological responses developed with time (Francis and Mitchell 2003).” “There are two theoretical considerations supporting recompression using oxygen. First, the rapid removal of the bubbles from recompression can prevent some of these secondary effects and avoid permanent tissue damage; and second there is the advantage of increased inspired oxygen partial pressure when pure oxygen is breathed, which can help counteract the effects of tissue hypoxia that may result from DCS-induced endothelium damage.

Don't leave it to chance.
Treatment for DCI is best performed in a hyperbaric chamber. But the stark reality is most incidences are unable to receive chamber treatment within 30 minutes from the onset of symptoms. And it is clear that the longer the hold-up to treatment, the poorer the chances are for a more effective recovery. Meanwhile, in-water recompression using oxygen or OIWR, is simple and easy to deploy within minutes from a decompression emergency. It has been in use for over 30 years with great success. With the proper equipment and training, and the right conditions, OIWR can be performed safely and can truly spell the difference between full recovery and permanent disability. Be prepared.
