[Hyperventilation in military aviation and diving]

ABSTRACT

The most important risk of aviation [in altitude over 10 thousand feet] and sub aquatic seafaring [in depth exceed over 30 meters] is hyperventilation. The problems manifested itself at first and especially second world war when pilots flew at altitude over 10 thousand feet. Those pilots had some signs and symptoms while faced mental and physical stresses that eventuated in aircraft crash. This study collected related data from several books, articles and knowledge about military and civil aviation. Etiology of hyperventilation is related to stressing [mental and physical problems] such as ambient changes [temperature, pressure and, etc], face to emergency situations, physiological and mental changes and, etc. Signs and symptoms were different in everyone this manifestations cause from motor and sensory impairment, psychomotor, cognitive, neuromuscular, consciousness and death. These risks are more important in military aviation due to highest performance and in seafaring because stresses in the work. The astronauts, air crews, sea crews and athletics always have consciousness and higher performance. Thus informing them about hyperventilation and its complications, prevention and treatment for population are necessary
