  2. Hypocapnia - Wikipedia

    en.wikipedia.org/wiki/Hypocapnia

    This risk is caused due to air hunger being reduced (due to low blood carbon dioxide levels) but oxygen levels not being increased. In fact hypocapnia reduces the oxygen levels available to the brain due to the elevated affinity of oxygen to hemoglobin (Bohr effect) hence highly increasing the chances of blackout.

  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. Hypoventilation - Wikipedia

    en.wikipedia.org/wiki/Hypoventilation

    By definition it causes an increased concentration of carbon dioxide (hypercapnia) and respiratory acidosis. Hypoventilation is not synonymous with respiratory arrest, in which breathing ceases entirely and death occurs within minutes due to hypoxia and leads rapidly into complete anoxia, although both are medical emergencies. Hypoventilation ...

    CO2 supplies have been disrupted by soaring gas prices and many industries are struggling with the fallout.

  6. Metabolic acidosis - Wikipedia

    en.wikipedia.org/wiki/Metabolic_acidosis

    Metabolic acidosis is a serious electrolyte disorder characterized by an imbalance in the body's acid-base balance.Metabolic acidosis has three main root causes: increased acid production, loss of bicarbonate, and a reduced ability of the kidneys to excrete excess acids. [5]

  7. Obesity hypoventilation syndrome - Wikipedia

    en.wikipedia.org/wiki/Obesity_hypoventilation...

    The high carbon dioxide can also cause headaches, which tend to be worsening in the morning. [ 6 ] The low oxygen level leads to physiologic constriction of the pulmonary arteries to correct ventilation-perfusion mismatching, which puts excessive strain on the right side of the heart.

  8. Hypoxemia - Wikipedia

    en.wikipedia.org/wiki/Hypoxemia

    Additionally, oxygen in a confined space can be consumed if carbon dioxide scrubbers are used without sufficient attention to supplementing the oxygen which has been consumed. Hypoxic or anoxic breathing gas mixtures, and exposure to a vacuum or other extreme low pressure environment will remove oxygen from the blood in the alveoli. [18]

  9. Photorespiration - Wikipedia

    en.wikipedia.org/wiki/Photorespiration

    This ability to avoid photorespiration makes these plants more hardy than other plants in dry and hot environments, wherein stomata are closed and internal carbon dioxide levels are low. Under these conditions, photorespiration does occur in C 4 plants, but at a much lower level compared with C 3 plants in the same conditions.
