Hyperventilation is irregular breathing that occurs when the rate or tidal volume of breathing eliminates more carbon dioxide than the body can produce. [ 1 ] [ 2 ] [ 3 ] This leads to hypocapnia , a reduced concentration of carbon dioxide dissolved in the blood.
Hyperventilation syndrome (HVS), also known as chronic hyperventilation syndrome (CHVS), dysfunctional breathing hyperventilation syndrome, cryptotetany, [1] [2] spasmophilia, [3] [4] [5] latent tetany, [4] [5] and central neuronal hyper excitability syndrome (NHS), [3] is a respiratory disorder, psychologically or physiologically based, involving breathing too deeply or too rapidly ...
An abrupt stop of pulmonary gas exchange lasting for more than five minutes may permanently damage vital organs, especially the brain. Lack of oxygen to the brain causes loss of consciousness . Brain injury is likely if respiratory arrest goes untreated for more than three minutes, and death is almost certain if more than five minutes.

Symptoms of early hypercapnia (i.e. where PaCO 2 is elevated but not extremely so) include flushed skin, full pulse, extrasystoles, muscle twitches, hand flaps, and possibly a raised blood pressure. In severe hypercapnia (generally PaCO 2 greater than 10 kPa or 75 mmHg ), symptomatology progresses to disorientation, panic , hyperventilation ...
The hyperventilation leads to an excessive elimination of carbon dioxide (CO 2) whereas no significant additional amounts of oxygen can be stocked in the body. As only carbon dioxide is responsible for the breathing stimulus, [ citation needed ] after hyperventilation, breath can be held longer until cerebral hypoxia occurs.
Self-induced hypocapnia through hyperventilation is the basis for the dangerous schoolyard fainting game. [ citation needed ] Deliberate hyperventilation has been used by underwater breath-hold divers for the purpose of extending dive time as it effectively reduces respiratory drive due to low CO 2 levels.
