    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.

    Acid–base and blood gases are among the few blood constituents that exhibit substantial difference between arterial and venous values. [6] Still, pH, bicarbonate and base excess show a high level of inter-method reliability between arterial and venous tests, so arterial and venous values are roughly equivalent for these. [44]

    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]

  6. Hypoxia (medicine) - Wikipedia

    An arterial blood gas test (ABG) may be done, which usually includes measurements of oxygen content, hemoglobin, oxygen saturation (how much of the hemoglobin is carrying oxygen), arterial partial pressure of oxygen (P a O 2), partial pressure of carbon dioxide (P a CO 2), blood pH level, and bicarbonate (HCO 3) [92]
