  3. 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]

    Example pulse oximeter. Pulse oximetry is a method used to estimate the percentage of oxygen bound to hemoglobin in the blood. [10] This approximation to SaO 2 is designated SpO 2 (peripheral oxygen saturation). The pulse oximeter is a small device that clips to the body (typically a finger, an earlobe or an infant's foot) and displays its ...

    In other levels of care, pulse oximetry plus transcutaneous carbon-dioxide measurement is a less invasive, alternative method of obtaining similar information. [citation needed] An ABG test can indirectly measure the level of bicarbonate in the blood. The bicarbonate level is calculated using the Henderson-Hasselbalch equation.

    Pain is measured on a 0–⁠10 pain scale based on subjective patient reporting and may be unreliable. [17] Some studies show that recording pain routinely may not change management. [18] [19] [20] Menstrual cycle [21] [22] Oxygen saturation (as measured by pulse oximetry) [23] [24] [25] Blood glucose level [26]

  7. Hypoxia (medicine) - Wikipedia

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

    Arterial oxygen tension can be measured by blood gas analysis of an arterial blood sample, and less reliably by pulse oximetry, which is not a complete measure of circulatory oxygen sufficiency. If there is insufficient blood flow or insufficient hemoglobin in the blood (anemia), tissues can be hypoxic even when there is high arterial oxygen ...
