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 ...
This is a shortened version of the fifth chapter of the ICD-9: Mental Disorders. It covers ICD codes 290 to 319 . The full chapter can be found on pages 177 to 213 of Volume 1, which contains all (sub)categories of the ICD-9.
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.
Paroxysmal sympathetic hyperactivity (PSH) is a syndrome that causes episodes of increased activity of the sympathetic nervous system.Hyperactivity of the sympathetic nervous system can manifest as increased heart rate, increased respiration, increased blood pressure, diaphoresis, and hyperthermia.

Central neurogenic hyperventilation (CNH) is an extremely rare neurological disorder that was initially reported by Fred Plum, MD and August G. Swanson, MD, in 1959. [ 6 ] [ 11 ] [ 1 ] Plum and Swanson described the symptoms of nine comatose patients, defining CNH as a syndrome consisting primarily of elevated arterial oxygen tension, decreased ...
Hyperventilation syndrome often presents with chest pain and a tingling sensation of the fingertips and around the mouth. Tuberculosis : Chest pain associated with tuberculosis often arises from tuberculous pericarditis, a condition caused by Mycobacterium tuberculosis affecting the pericardium.
Pitt–Hopkins syndrome (PTHS) is a rare genetic disorder characterized by developmental delay, moderate to severe intellectual disability, [1] distinctive facial features, and possible intermittent hyperventilation followed by apnea. [2]
Hyperpnea is also distinguished from hyperventilation, which is over-ventilation (an increase in minute ventilation), which involves an increase in volume and respiration rate, resulting in rapid and deep breaths. The exact mechanisms behind exercise hyperpnea are not well understood, and some hypotheses are somewhat controversial.
