2. Normal Pulse Oximetry Ranges and How to Take a Reading - AOL

   www.aol.com/normal-pulse-oximetry-ranges-reading...

   Normal Ranges. Most people have a normal resting pulse oximetry reading for oxygen saturation (SpO2) between 95% and 100%. This shows that your blood has an appropriate amount of oxygen. People at ...

3. Pulse oximetry - Wikipedia

   en.wikipedia.org/wiki/Pulse_oximetry

   The ratio of the AC component to the DC component, expressed as a percentage, is known as the (peripheral) perfusion index (Pi) for a pulse, and typically has a range of 0.02% to 20%. [43] An earlier measurement called the pulse oximetry plethysmographic (POP) only measures the "AC" component, and is derived manually from monitor pixels. [41] [44]

4. Oxygen saturation (medicine) - Wikipedia

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

   Oxygen saturation (medicine) Oxygen saturation is the fraction of oxygen -saturated haemoglobin relative to total haemoglobin (unsaturated + saturated) in the blood. 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]

5. Vital signs - Wikipedia

   [1] [2] The normal ranges for a person's vital signs vary with age, weight, sex, and overall health. [3] There are four primary vital signs: body temperature, blood pressure, pulse , and breathing rate (respiratory rate), often notated as BT, BP, HR, and RR. However, depending on the clinical setting, the vital signs may include other ...

6. Reference ranges for blood tests - Wikipedia

   en.wikipedia.org/wiki/Reference_ranges_for_blood...

   Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...

7. Hypoxemia - Wikipedia

   en.wikipedia.org/wiki/Hypoxemia

   Definition. Hypoxemia refers to the low level of oxygen in blood, and the more general term hypoxia is an abnormally low oxygen content in any tissue or organ, or the body as a whole. [2] Hypoxemia can cause hypoxia (hypoxemic hypoxia), but hypoxia can also occur via other mechanisms, such as anemia. [4]
