2. Hypoxemia - Wikipedia

   en.wikipedia.org/wiki/Hypoxemia

   Definition. Hypoxemia refers to the low level of oxygen in blood, and the more general term hypoxia is an abnormally low oxygen content in any tissue or organ, or the body as a whole. [2] Hypoxemia can cause hypoxia (hypoxemic hypoxia), but hypoxia can also occur via other mechanisms, such as anemia. [4]

3. Oxygen saturation (medicine) - Wikipedia

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

   Oxygen saturation (medicine) Oxygen saturation is the fraction of oxygen -saturated haemoglobin relative to total haemoglobin (unsaturated + saturated) in the blood. The human body requires and regulates a very precise and specific balance of oxygen in the blood. Normal arterial blood oxygen saturation levels in humans are 96–100 percent. [1]

4. Hypoxia (medicine) - Wikipedia

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

   Hypoxia is a condition in which the body or a region of the body is deprived of adequate oxygen supply at the tissue level. [ 1 ] Hypoxia may be classified as either generalized, affecting the whole body, or local, affecting a region of the body. [ 2 ] Although hypoxia is often a pathological condition, variations in arterial oxygen ...

5. Normal Pulse Oximetry Ranges and How to Take a Reading - AOL

   Normal Ranges. Most people have a normal resting pulse oximetry reading for oxygen saturation (SpO2) between 95% and 100%. This shows that your blood has an appropriate amount of oxygen. People at ...

6. Syncope (medicine) - Wikipedia

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

   The respiratory system may compensate for dropping oxygen levels through hyperventilation, though a sudden ischemic episode may also proceed faster than the respiratory system can respond. [9] These processes cause the typical symptoms of fainting: pale skin, rapid breathing, nausea, and weakness of the limbs, particularly of the legs. [3]

7. Effects of high altitude on humans - Wikipedia

   en.wikipedia.org/wiki/Effects_of_high_altitude...

   Climbing Mount Rainier.. The effects of high altitude on humans are mostly the consequences of reduced partial pressure of oxygen in the atmosphere. The medical problems that are direct consequence of high altitude are caused by the low inspired partial pressure of oxygen, which is caused by the reduced atmospheric pressure, and the constant gas fraction of oxygen in atmospheric air over the ...
