Hyperventilation
Hyperventilation is excessive breathing — breathing faster and/or deeper than the body requires.
It is commonly brought on by anxiety, fear or stress, although hypoxia and physical strain may also cause it.
During hyperventilation, more carbon dioxide is breathed out than the body is producing.
This causes the carbon dioxide level in the blood to fall and the blood to become more alkaline.
These changes can produce symptoms such as dizziness, tingling, visual disturbances and muscle stiffness.
If hyperventilation continues, the person may eventually become unconscious. Once unconscious, breathing normally returns towards its normal rate and depth.
