  2. Hypoxemia - Wikipedia

    en.wikipedia.org/wiki/Hypoxemia

    Hypoxemia (also spelled Hypoxaemia) is an abnormally low level of oxygen in the blood. [1] [2] More specifically, it is oxygen deficiency in arterial blood. [3] Hypoxemia is usually caused by pulmonary disease. Sometimes the concentration of oxygen in the air is decreased leading to hypoxemia.

  3. Hypoxia (medicine) - Wikipedia

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

    Hemoglobin plays a substantial role in carrying oxygen throughout the body, [62] and when it is deficient, anemia can result, causing 'anaemic hypoxia' if tissue oxygenation is decreased. Iron deficiency is the most common cause of anemia. As iron is used in the synthesis of hemoglobin, less hemoglobin will be synthesised when there is less ...

  4. Oxygen saturation (medicine) - Wikipedia

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

    Continued low oxygen levels may lead to respiratory or cardiac arrest. Oxygen therapy may be used to assist in raising blood oxygen levels. Oxygenation occurs when oxygen molecules (O 2) enter the tissues of the body. For example, blood is oxygenated in the lungs, where oxygen molecules travel from the air and into the blood. Oxygenation is ...

  5. Asphyxia - Wikipedia

    en.wikipedia.org/wiki/Asphyxia

    Asphyxia or asphyxiation is a condition of deficient supply of oxygen to the body which arises from abnormal breathing. [3] [4] Asphyxia causes generalized hypoxia, which affects all the tissues and organs, some more rapidly than others.

  6. 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 ...

  7. Cerebral hypoxia - Wikipedia

    en.wikipedia.org/wiki/Cerebral_hypoxia

    Blood flow may increase up to twice the normal flow but no more. If the increased blood flow is sufficient to supply the brain's oxygen needs then no symptoms will result. [6] However, if blood flow cannot be increased or if doubled blood flow does not correct the problem, symptoms of cerebral hypoxia will begin to appear.

  8. Ischemia - Wikipedia

    en.wikipedia.org/wiki/Ischemia

    Ischemia or ischaemia is a restriction in blood supply to any tissue, muscle group, or organ of the body, causing a shortage of oxygen that is needed for cellular metabolism (to keep tissue alive). [ 3 ] [ 4 ] Ischemia is generally caused by problems with blood vessels , with resultant damage to or dysfunction of tissue i.e. hypoxia and ...

    en.wikipedia.org/wiki/Hypoxia

    Anemic hypoxia, Blood is not able to take sufficient amount of oxygen due to Anemia; Hypoxemic hypoxia or hypoxemia, a deficiency of oxygen in arterial blood; Hypoxic hypoxia, a result of insufficient oxygen available to the lungs; Intrauterine hypoxia, when a fetus is deprived of an adequate supply of oxygen
