Follow these steps: Turn on the pulse oximeter and place it on your fingertip, ideally the middle or index finger. Sit still and avoid moving while the device reads your oxygen levels and heart ...
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]
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 reading, or transfers it to ...
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]
Pulse oximeters are more likely to produce inaccurate blood oxygen results in Black, Latino and Asian Americans than in white patients, delaying Covid-19 treatment.

Transcutaneous oxygen measurement. Transcutaneous oxygen measurement (TCOM or TcPO 2) is a non-invasive method of measuring the oxygen level of the tissue below the skin. Since oxygen is carried by the blood, TCOM can be used as an indirect measure of blood flow to the tissue. Since blood flow is important for wound healing, TCOM is often used ...
A pulse oximeter works by beaming red and infrared light through capillaries. The amount of red and infrared light transmitted provides an approximate measure of oxygen in the blood. The oximeter reading is based on the color of the blood: oxygenated blood is a brighter red than deoxygenated blood, which appears as bluish purple.
