Hyperventilation
What is hyperventilation and what to do when it happens?
One of the most frightening experiences in which someone can happen is a fit of hyperventilation.
It is a terrifying feeling of suffocation that forces the sufferer to breathe quickly and deeply. This symptom-ing some time, real-mind leaves a person with a sense of lack of oxygen.
Why should this symptom?
The Feeling very anxious or having a panic attack are the most common reasons why you may experience hyperventilation. However, the rapid breathing may be a symptom-making of an underlying disease such as coronary or lung disorder, bleeding or infection.
Hyperventilation is common in young adults. It is more common in women, although it is also common in men.
What happens in a fit of hyperventilation? 
Although victims of an attack like this breathe desperately trying to introduce oxygen into the lungs, their real problem, oddly enough, is that they are absorbing too much air. Instead of making them feel better, that deep and rapid breathing makes it worse because it makes much lower level of carbon dioxide in the blood.
We used to think that oxygen is always “good” for the body and carbon dioxide “harmful”, but the truth is that only need a certain amount of oxygen normally in the body must be certain level of carbon dioxide that can carry out gas exchange.
A few minutes into hyperventilation, the person experiences dizziness, sweating, tachycardia, and tingling or numbness of the hands and feet and even faints, possibly confusing the state with a heart attack.
What can you do?
Fortunately, there is an easy way to stop the attack: the affected person to breathe for a few minutes inside a paper bag.
As part of the carbon dioxide breathed into the lungs again and restores balance in the blood between the gas and oxygen, the breath is becoming normal. If the patient faints, can stop breathing momentarily, but recovered his breath as the body build up enough carbon dioxide.
