In a study published in February, they found that Black patients’ blood oxygen readings on pulse oximeters were on average 6% higher than the actual blood oxygen levels measured in their ...
Inaccurate pulse oximeter readings among Black and brown people exacerbate racial health disparities, the attorneys general said, and can lead to delayed treatment, a lower rate of hospital ...
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.

Story at a glance FDA panel meets to discuss pulse oximeters, which are medical devices that measure blood oxygen levels. Studies have suggested that oximeter readings are less accurate for people ...
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 ...
The longstanding problem of pulse oximeters providing less-accurate readings for people with dark skin tones got another look Friday from a panel of experts for the US Food and Drug Administration.
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.
The findings are important as high levels of skin pigmentation are linked to ethnic groups who have a poorer outcome from Covid-19, researchers say. Inaccurate blood oxygen device readings ...
