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)

   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.

4. Oxygen saturation (medicine) - Wikipedia

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

   Normal arterial blood oxygen saturation levels in humans are 96–100 percent. [1] If the level is below 90 percent, it is considered low and called hypoxemia. [2] Arterial blood oxygen levels below 80 percent may compromise organ function, such as the brain and heart, and should be promptly addressed. Continued low oxygen levels may lead to ...

7. 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 ...

8. Ventilation–perfusion coupling - Wikipedia

   en.wikipedia.org/wiki/Ventilation–perfusion...

   Pulmonary embolism is blood clots occurring in the lungs. Restricted blood flow in the pulmonary circulation results in alveoli ventilated but not perfused, thus, increasing the V/Q ratio and decreasing gas exchange. It can cause hypoxemia(low oxygen level) and damage part of the lung, which may be treated with anticoagulants.

9. Hypoxic pulmonary vasoconstriction - Wikipedia

   en.wikipedia.org/wiki/Hypoxic_pulmonary...

   Hypoxic pulmonary vasoconstriction (HPV), also known as the Euler–Liljestrand mechanism, is a physiological phenomenon in which small pulmonary arteries constrict in the presence of alveolar hypoxia (low oxygen levels). By redirecting blood flow from poorly-ventilated lung regions to well-ventilated lung regions, HPV is thought to be the ...
