Hyperventilation

Definition

noun

(1) Excessive ventilation

(2) A condition characterized by prolonged breathing of air at a faster rate than the normal or when at rest


Supplement

Hyperventilation in humans may lead to dizziness, fainting, light headedness, and cramps. That is because hyperventilation results in decreased carbon dioxide in the blood below the normal level since it is expired faster than being produced in the body. When this happens the pH level of the blood rises. This in turn causes blood vessels to constrict, which then slows down oxygen transport into various body parts, including the brain.

Respiratory vs metabolic acidosis/alkalosis

... exchange; that is to say, the body is not keeping up with the demand, or exceeding it. The two textbook causes are hypoventilation (acidosis), and hyperventilation (alkalosis). As a result of aerobic respiration, your body produces CO2, which when mixed with water, creates H2CO3, which disassociates ...

Re: Tachypnea vs. Hyperventilation

Think about this, hypocarbia takes place when we hyperventilate since the CO2 levels in our blood decreases and more O2 levels on the other hand. CO2 is not just merely a gaseous waste. It actually stimulates us to breathe. The moment that our body senses that this gas is below the normal, we compen...

Perspiration among carnivores [mammals].

I don't know about the evolution question you asked, but carnivores maintain thermostasis through hyperventilation (think of panting dogs in the summertime).
