Cary hyperventilates for several minutes before diving into a swimming pool. Shortly after he enters the water and begins swimming, he blacks out and almost drowns. What caused this to happen?
2 possibilities:
First when you hyperventilate you are blowing off carbon dioxide.this makes your body more alkaline(respiratory alkalosis.)If you blood gets too alkaline you pass out.
Second,since it is rising carbon dioxide levels that warn you that you need to breath you can run out of enough oxygen in your blood(and brain) without knowing you need to breath and pass out.
