hyperventilation - why is it so seldom diagnosed in people?

It is usually: Diagnosed as panic disorder because hyperventilation in the absence of other symptoms of panic is rare. Some other illnesses that can trigger hyperventilation are strokes, lung disease, over-exhaustion, and head injuries.

Why does hyperventilation reduce intracranial pressure?

Vasoconstriction: Hyperventilation causes low carbon dioxide which leads to increased blood pH level (alkalosis) which causes blood vessels to constrict. Alkalosis also causes decreased freely ionized blood calcium, which results in cell membrane instability and subsequent blood vessel constriction. Hyperventilation reduces intracranial pressure as a result of this vasoconstriction within the brain.

A 40-year-old member asked:
I have difficulty catching breath. Could this be due to hyperventilation?

Not really: Hyperventilation is the normal reaction by the body to a situation where increased minute ventilation (both rate and depth of breathing) is required, such as exercise. If one hyperventilates while at rest, it can indicate either pulmonary disease, heart disease, central nervous system disorder, anemia, or anxiety. All of these situations should be evaluated by a physician or other provider.

Is there a way to treat hyperventilation?

Yes: If you are breathing too fast for no physiologic reason, such as for fever or vigorous exercise, then breathing into a paper bag would be helpful.

Hyperventilation, what size paper bag?
1 doctor answer • 1 doctor weighed in

Whatever: Can you still find a paper bag? The idea is to build up co2 levels so the smallest bag that will cover both your nose and mouth and hold a good breath would work. But a big bag would probably work almost as fast if that's all you have. Plastic would not be a good idea.

Aw, c'mon: As long as you are getting high; why care about destroying your brain.
