Causes of the Bends

The direct cause is due to bubble formation and growth within body organs and tissues. Mainly seen in divers but can be seen in high altitude pilots or astronauts as well as persons working in compressed air environments. The exact mechanisms are not fully understood but rapid ascents from depth or sudden decompression as well as incorrect decompression procedures do seem to be a cause. Effects differ from person to person but varying predisposing factors are thought to heavily contribute to DCI even with correct procedures. Breath holding and air trapping in the lungs during ascent or decompression may also lead to DCI as well as some heart defects.
