  2. Hypoxemia - Wikipedia

    en.wikipedia.org/wiki/Hypoxemia

    Other names. Hypoxaemia. Blood with higher oxygen content appears bright red. Specialty. Pulmonology. Hypoxemia is an abnormally low level of oxygen in the blood. [ 1][ 2] More specifically, it is oxygen deficiency in arterial blood. [ 3] Hypoxemia has many causes, and often causes hypoxia as the blood is not supplying enough oxygen to the ...

  3. Oxygen saturation (medicine) - Wikipedia

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

    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] 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 ...

  4. List of medical symptoms - Wikipedia

    en.wikipedia.org/wiki/List_of_medical_symptoms

    [1] [2] Patients observe these symptoms and seek medical advice from healthcare professionals. Because most people are not diagnostically trained or knowledgeable, they typically describe their symptoms in layman's terms, rather than using specific medical terminology. This list is not exhaustive.

  5. What Is a Normal Oxygen Level and How Can I Check Mine? - AOL

    What is a good oxygen level? “Normal people who have working lungs, and all those steps are going well, their blood oxygen level will usually be 96-100 percent,” adds Dr. Uppal. A few notches ...

  6. Hypopnea - Wikipedia

    en.wikipedia.org/wiki/Hypopnea

    Hypopnea is typically defined by a decreased amount of air movement into the lungs and can cause oxygen levels in the blood to drop. It commonly is due to partial obstruction of the upper airway. Hypopnea during sleep is classed as a sleep disorder. With moderate to severe hypopnea, sleep is disturbed such that patients may get a full night's ...

  7. Hyperoxia - Wikipedia

    en.wikipedia.org/wiki/Hyperoxia

    Hyperoxia occurs when cells, tissues and organs are exposed to an excess supply of oxygen (O 2) or higher than normal partial pressure of oxygen. [1]In medicine, it refers to excessive oxygen in the lungs or other body tissues, and results from raised alveolar oxygen partial pressure - that is, alveolar oxygen partial pressure greater than that due to breathing air at normal (sea level ...

  8. Oxygen toxicity - Wikipedia

    en.wikipedia.org/wiki/Oxygen_toxicity

    Oxygen toxicity is a condition resulting from the harmful effects of breathing molecular oxygen ( O. 2) at increased partial pressures. Severe cases can result in cell damage and death, with effects most often seen in the central nervous system, lungs, and eyes. Historically, the central nervous system condition was called the Paul Bert effect ...

  9. Cerebral hypoxia - Wikipedia

    en.wikipedia.org/wiki/Cerebral_hypoxia

    Cerebral hypoxia refers to oxygen levels in brain tissue, not blood. Blood oxygenation will usually appear normal in cases of hypemic, ischemic, and hystoxic cerebral hypoxia. Even in hypoxic hypoxia blood measures are only an approximate guide; the oxygen level in the brain tissue will depend on how the body deals with the reduced oxygen ...
