Hyperventilation (or overbreathing) is the state of breathing faster and/or deeper than necessary, bringing about lightheadedness and other undesirable symptoms often associated with panic attacks. Hyperventilation can also be a response to metabolic acidosis, a condition that causes acidic blood pH levels.
Counterintuitively, such side effects are not precipitated by the sufferer's lack of oxygen or air. Rather, the hyperventilation itself reduces the carbon dioxide concentration of the blood to below its normal level, thereby raising the blood's pH value (making it more alkaline), initiating constriction of the blood vessels which supply the brain, and preventing the transport of oxygen and other molecules necessary for the function of the nervous system.[1]
Lungs and breathing activity
Commonly confused terminology
view • talk • edit
Shortness of breath or dyspnea - sensation of respiratory distress
Labored breathing - physical presentation of respiratory distress
Hyperventilation - increased breathing that causes CO2 loss
Hyperpnea - faster and/or deeper breathing
Tachypnea - increased breathing rate
Hyperaeration/Hyperinflation - increased lung volume
Hyperventilation can, but does not necessarily always cause symptoms such as numbness or tingling in the hands, feet and lips, lightheadedness, dizziness, headache, chest pain, slurred speech, nervous laughter, and sometimes fainting, particularly when accompanied by the Valsalva maneuver. Sometimes hyperventilation is induced for these same effects. - Reply
