So, it is not a lack of oxygen or nitrogen, it is the air pressure that makes us sick from the barotrauma. It is starting to make sense. Thank you, Doc!
When an IED explodes, it causes blast-induced barotrauma. If it doesn't kill you, it knocks the wind out of you which is actually the low air pressure after the shock wave passes.
Atomic bomb experiments show the initial blast and shock wave that causes low pressure. When the shock wave dissipates, the surrounding air rushes back in.
So, if you live and train at altitude...I remember the 1968 Olympics in Mexico City. The athletes trained at altitude in Oregon to prepare.
I like this subject.
