  2. Hypoxemia - Wikipedia

    en.wikipedia.org/wiki/Hypoxemia

    Tissue hypoxia refers to low levels of oxygen in the tissues of the body and the term hypoxia is a general term for low levels of oxygen. [2] Hypoxemia is usually caused by pulmonary disease whereas tissue oxygenation requires additionally adequate circulation of blood and perfusion of tissue to meet metabolic demands.

  3. Arterial blood gas test - Wikipedia

    en.wikipedia.org/wiki/Arterial_blood_gas_test

    A low PaO 2 indicates abnormal oxygenation of blood and a person is known as having hypoxemia. (Note that a low PaO 2 is not required for the person to have hypoxia as in cases of Ischemia, a lack of oxygen in tissues or organs as opposed to arterial blood.) At a P a O 2 of less than 60 mm Hg, supplemental oxygen should be administered.

  4. Hypoxia (medicine) - Wikipedia

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

    Hypoxemic hypoxia is a lack of oxygen caused by low oxygen tension in the arterial blood, due to the inability of the lungs to sufficiently oxygenate the blood. Causes include hypoventilation, impaired alveolar diffusion, and pulmonary shunting. [8] This definition overlaps considerably with that of hypoxic hypoxia.

    The process might initially seem counterintuitive, as low oxygen levels might theoretically stimulate increased blood flow to the lungs to increase gas exchange. However, the purpose of HPV is to distribute bloodflow regionally to increase the overall efficiency of gas exchange between air and blood.

  9. Intermittent hypoxic training - Wikipedia

    en.wikipedia.org/wiki/Intermittent_hypoxic_training

    Intermittent hypoxic training (IHT), also known as intermittent hypoxic therapy, is a technique aimed at improving human performance by way of adaptation to reduced oxygen. An IHT session consists of an interval of several minutes breathing hypoxic (low oxygen) air, alternated with intervals breathing ambient (normoxic) or hyperoxic air.
