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 ...
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. CNH is unrelated to other forms of hyperventilation, like Kussmaul's ...
Hypocapnia (from the Greek words ὑπό meaning below normal and καπνός kapnós meaning smoke), also known as hypocarbia, sometimes incorrectly called acapnia, is a state of reduced carbon dioxide in the blood. [1] Hypocapnia usually results from deep or rapid breathing, known as hyperventilation. Hypocapnia is the opposite of hypercapnia.
Hyperpnea – fast and deep breathing; Hyperventilation – increased breathing that causes CO 2 loss; Hypopnea – slow and shallow breathing; Hypoventilation – decreased breathing that causes CO 2 gain; Labored breathing – physical presentation of respiratory distress; Tachypnea – increased breathing rate
Irregularities in breathing, including hyperventilation and shortness of breath, are key features of anxiety and panic attacks. [63] Hyperventilation syndrome occurs when an individual experiences deep, quick-paced breathing, eventually affecting blood flow to the brain and altering conscious awareness.
Breathing is normally an unconscious, involuntary, automatic process. The pattern of motor stimuli during breathing can be divided into an inhalation stage and an exhalation stage. Inhalation shows a sudden, ramped increase in motor discharge to the respiratory muscles (and the pharyngeal constrictor muscles). [5]
The Buteyko method emphasizes the role of carbon dioxide and hyperventilation in respiratory diseases as well as overall health. It is known that hyperventilation can lead to low carbon dioxide levels in the blood (or hypocapnea), which can subsequently lead to disturbances of the acid-base balance in the blood and lower tissue oxygen levels.
