What is Hyperventilation?
Hyperventilation is the term associated with rapid breathing, which is breathing that is in excess of what the body needs to function. Rapid breathing can be the result of a physical ailment or a psychosomatic - or emotional - response to a particular environment or event. The term hyperventilation syndrome relates to an over breathing pattern. Some patients may not even be aware that they are over breathing.
Hyperventilation is normally associated with anxiety or panic attacks, but it can be much more. Often, hyperventilation and panic work off each other - one feels panicked and starts hyperventilating; the feeling of not being able to breathe makes one feel even more panicked.
Hyperventilation syndrome may seem similar to anxiety or panic attacks, but it is really quite different. Panic disorders are associated with such things as fear of death or claustrophobia. With hyperventilation syndrome, however, the rapid breathing occurs without a particular emotional complaint (for example with asthma, emphysema, or lung cancer).
The Effects of Hyperventilation on the Body
Normal lung function clears out carbon dioxide (CO2) from the bloodstream. With hyperventilation, CO2 levels drop in the blood resulting in reduced blood flow to the brain and associated weakness, fainting, dizziness, confusion, agitation, and feeling like you can't breathe. In extreme cases, particularly for those patients with a history of heart disease, low carbon dioxide levels can cause spasms of the blood vessels that lead to the heart; spasms enough to cause a heart attack.
Hyperventilation can also cause a decrease in calcium levels in the blood, resulting in numbness or tingling usually in the arms and around the mouth, spasms or cramping of the hands and feet, and twitching muscles.
Hyperventilation symptoms usually:
- last hours as opposed to minutes
- occur in younger people
- improve with exercise
- do not improve with administering of heart medications
