(1) Selection of bends-resistant individuals
(2) Thorough denitrogenation before flight
(3) Limitation of decompressive pressure changes by appropriate choice
of cabin atmosphere pressure and composition
(4) Space-suit pressure setting
In some cases, further improvements might be obtained by using, in the
cabin atmosphere, an inert-gas component which has a lower solubility in
tissue and body fluids or less tendency than nitrogen to form bubbles.
