  2. Hypocapnia - Wikipedia

    en.wikipedia.org/wiki/Hypocapnia

    Acute hypocapnia causes hypocapnic alkalosis, which causes cerebral vasoconstriction leading to cerebral hypoxia, and this can cause transient dizziness, fainting, and anxiety. [3] A low partial pressure of carbon dioxide in the blood also causes alkalosis (because CO 2 is acidic in solution), leading to lowered plasma calcium ions ...

  3. Effect of oxygen on chronic obstructive pulmonary disease

    en.wikipedia.org/wiki/Effect_of_oxygen_on...

    Many people with chronic obstructive pulmonary disease have a low partial pressure of oxygen in the blood and high partial pressure of carbon dioxide.Treatment with supplemental oxygen may improve their well-being; alternatively, in some this can lead to the adverse effect of elevating the carbon dioxide content in the blood (hypercapnia) to levels that may become toxic.

  4. Hyperventilation - Wikipedia

    en.wikipedia.org/wiki/Hyperventilation

    The symptoms of respiratory alkalosis include dizziness, tingling in the lips, hands, or feet, headache, weakness, fainting, and seizures. In extreme cases, it may cause carpopedal spasms, a flapping and contraction of the hands and feet. [3] [4]

  5. Hyperventilation syndrome - Wikipedia

    en.wikipedia.org/wiki/Hyperventilation_syndrome

    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 ...

  6. Hypercapnia - Wikipedia

    en.wikipedia.org/wiki/Hypercapnia

    Carbon dioxide is a gaseous product of the body's metabolism and is normally expelled through the lungs. Carbon dioxide may accumulate in any condition that causes hypoventilation, a reduction of alveolar ventilation (the clearance of air from the small sacs of the lung where gas exchange takes place) as well as resulting from inhalation of CO 2.

  7. Respiratory acidosis - Wikipedia

    en.wikipedia.org/wiki/Respiratory_acidosis

    Acute respiratory acidosis occurs when an abrupt failure of ventilation occurs. This failure in ventilation may be caused by depression of the central respiratory center by cerebral disease or drugs, inability to ventilate adequately due to neuromuscular disease (e.g., myasthenia gravis, amyotrophic lateral sclerosis, Guillain–Barré syndrome, muscular dystrophy), or airway obstruction ...

  8. Masks don't hurt lung function or cause CO2 buildup - AOL

    www.aol.com/news/masks-dont-hurt-lung-function...

    Contrary to viral claims, wearing surgical masks or cloth face coverings does not restrict the amount of oxygen a person breathes in, nor does it cause a dangerous buildup of carbon dioxide ...

  9. Respiratory failure - Wikipedia

    en.wikipedia.org/wiki/Respiratory_failure

    Respiratory failure is classified as either Type 1 or Type 2, based on whether there is a high carbon dioxide level, and can be acute or chronic. In clinical trials, the definition of respiratory failure usually includes increased respiratory rate , abnormal blood gases (hypoxemia, hypercapnia, or both), and evidence of increased work of breathing.
