  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 ...

    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 ...

  4. Oxygen saturation - Wikipedia

    en.wikipedia.org/wiki/Oxygen_saturation

    In medicine, oxygen saturation refers to oxygenation, or when oxygen molecules (O 2) enter the tissues of the body. In this case blood is oxygenated in the lungs, where oxygen molecules travel from the air into the blood. Oxygen saturation ((O 2) sats) measures the percentage of hemoglobin binding sites in the bloodstream occupied by oxygen ...

    en.wikipedia.org/wiki/Arterial_blood_gas_test

    The blood can also be drawn from an arterial catheter. An ABG test measures the blood gas tension values of the arterial partial pressure of oxygen (PaO2), and the arterial partial pressure of carbon dioxide (PaCO2), and the blood's pH. In addition, the arterial oxygen saturation (SaO2) can be determined. Such information is vital when caring ...

  6. Pulse oximetry - Wikipedia

    en.wikipedia.org/wiki/Pulse_oximetry

    A pulse oximeter probe applied to a person's finger. A pulse oximeter is a medical device that indirectly monitors the oxygen saturation of a patient's blood (as opposed to measuring oxygen saturation directly through a blood sample) and changes in blood volume in the skin, producing a photoplethysmogram that may be further processed into other measurements. [4]

  9. Oxygen–hemoglobin dissociation curve - Wikipedia

    en.wikipedia.org/wiki/Oxygen–hemoglobin...

    The oxygen–hemoglobin dissociation curve, also called the oxyhemoglobin dissociation curve or oxygen dissociation curve (ODC), is a curve that plots the proportion of hemoglobin in its saturated (oxygen-laden) form on the vertical axis against the prevailing oxygen tension on the horizontal axis. This curve is an important tool for ...
