  2. 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 ...

  3. Hypoxemia - Wikipedia

    en.wikipedia.org/wiki/Hypoxemia

    Serious hypoxemia typically occurs when the partial pressure of oxygen in blood is less than 60 mmHg (8.0 kPa), the beginning of the steep portion of the oxygen–hemoglobin dissociation curve, where a small decrease in the partial pressure of oxygen results in a large decrease in the oxygen content of the blood.

    One of those vital signs is blood oxygen level, and in the hospital, it’s measured with a pulse oximeter. Patients with Covid-19 can sometimes have relatively mild symptoms and seem to be ...

  5. Blood gas tension - Wikipedia

    en.wikipedia.org/wiki/Blood_gas_tension

    Arterial blood oxygen tension (normal) P a O 2 – Partial pressure of oxygen at sea level (160 mmHg in the atmosphere, 21% of standard atmospheric pressure of 760 mmHg) in arterial blood is between 75 mmHg and 100 mmHg. [4] [5] [6] Venous blood oxygen tension (normal) P v O 2 – Oxygen tension in venous blood at sea level is between 30 mmHg ...

  6. Hyperoxia - Wikipedia

    en.wikipedia.org/wiki/Hyperoxia

    Hyperoxia is the state of being exposed to high levels of oxygen; it may refer to organisms, cells and tissues that are experiencing excessive oxygenation, [1] or to an abnormally high oxygen concentration in an environment (e.g. a body of water).

  7. Hypopnea - Wikipedia

    en.wikipedia.org/wiki/Hypopnea

    One treatment for obstructive hypopnea is continuous positive airway pressure (CPAP). CPAP is a treatment in which the patient wears a mask over the nose and/or mouth. An air blower forces air through the upper airway. The air pressure is adjusted so that it is just enough to maintain the oxygen saturation levels in the blood.

    To date, Dr. Uppal says he’s overseen the treatment of more than 300 Covid-19 patients, all with varying levels of blood oxygen. What is a good oxygen level? “Normal people who have working ...

  9. Respiratory failure - Wikipedia

    en.wikipedia.org/wiki/Respiratory_failure

    Respiratory failure results from inadequate gas exchange by the respiratory system, meaning that the arterial oxygen, carbon dioxide, or both cannot be kept at normal levels. A drop in the oxygen carried in the blood is known as hypoxemia; a rise in arterial carbon dioxide levels is called hypercapnia. Respiratory failure is classified as ...
