  2. Hypoxia (medicine) - Wikipedia

    en.wikipedia.org/wiki/Hypoxia_(medicine)

    In this situation there is not enough oxygen in the alveolar gas to fully oxygenate the blood volume passing through, and P a O 2 will be low. Conversely, an increased V/Q ratio tends to be a consequence of impaired perfusion, in which circumstances the blood supply is insufficient to carry the available oxygen, P a O 2 will be normal, but ...

  4. 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.

  5. Generalized hypoxia - Wikipedia

    en.wikipedia.org/wiki/Generalized_hypoxia

    Generalized hypoxia is a medical condition in which the tissues of the body are deprived of the necessary levels of oxygen due to an insufficient supply of oxygen, which may be due to the composition or pressure of the breathing gas, decreased lung ventilation, or respiratory disease, any of which may cause a lower than normal oxygen content in the arterial blood, and consequently a reduced ...

    One of those vital signs is blood oxygen level, and in the hospital, it’s measured with a pulse oximeter. Patients with Covid-19 can sometimes have relatively mild symptoms and seem to be ...

  7. Respiratory failure - Wikipedia

    en.wikipedia.org/wiki/Respiratory_failure

    Respiratory failure results from inadequate gas exchange by the respiratory system, meaning that the arterial oxygen, carbon dioxide, or both cannot be kept at normal levels. A drop in the oxygen carried in the blood is known as hypoxemia; a rise in arterial carbon dioxide levels is called hypercapnia. Respiratory failure is classified as ...

  9. Cerebral hypoxia - Wikipedia

    en.wikipedia.org/wiki/Cerebral_hypoxia

    Blood oxygen saturation may be used for hypoxic hypoxia, but is generally meaningless in other forms of hypoxia. In hypoxic hypoxia 95–100% saturation is considered normal; 91–94% is considered mild and 86–90% moderate. Anything below 86% is considered severe. [8] Cerebral hypoxia refers to oxygen levels in brain tissue, not blood.
