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 .
Risks, as noted in a 2021 study in Lifestyle Medicine, include cold shock, which can trigger hyperventilation and heart conditions. Plunge with caution.— Plunge with caution.— Kathleen Hou ...
Causes may include heart failure, kidney failure, narcotic poisoning, intracranial pressure, and hypoperfusion of the brain (particularly of the respiratory center). The pathophysiology of Cheyne–Stokes breathing can be summarized as apnea leading to increased CO 2 which causes excessive compensatory hyperventilation, in turn causing decreased CO 2 which causes apnea, restarting the cycle.
In many patients with ENS, the airflow is modeled as being more turbulent with less laminar flow across the mucosa. This change in airflow leads to an imbalance of CO 2 / O 2 levels [citation needed] in the body, which will show hyperventilation-like symptoms in patients. This reduced amount of mucus in the nose can also be attributed to the ...
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.
