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 ...
Symptoms can include hyperventilation, hyperthermia (fever), gastrointestinal discomfort, diarrhoea, hives, vomiting, delirium, hepatitis, [8] jaundice, anorexia, convulsions, coma and death. [7] Fatty degeneration of the heart and kidneys, necrosis of hepatic cells [ 9 ] in addition to yellow atrophy of the liver have been recorded in autopsy ...
Sleep apnea is a common sleep disorder that affects more than 20 percent of people in the United States. It happens when your breathing temporarily stops while you sleep. Depending on the severity ...
The main physiologic causes of hypocapnia are related to hyperventilation. Hypocapnia is sometimes induced in the treatment of medical emergencies such as intracranial hypertension [3] and hyperkalemia. Self-induced hypocapnia through hyperventilation is the basis for the dangerous schoolyard fainting game.
The toxic effects of salicylates have been described since at least 1877. [5] In 2004, more than 20,000 cases with 43 deaths were reported in the United States. [1] About 1% of those with an acute overdose die, while chronic overdoses may have severe outcomes. [3] Older people are at higher risks of toxicity for any given dose. [5]
Central neurogenic hyperventilation (CNH) is an abnormal pattern of breathing characterized by deep and rapid breaths at a rate of at least 25 breaths per minute. Increasing irregularity of this respiratory rate generally is a sign that the patient will enter into coma .
Treatment-emergent central sleep apnea (TECSA), also known as complex sleep apnea, is a type of sleep apnea that typically develops when a patient starts CPAP therapy for OSA. This can occur when ...
