The meeting conducted on Tuesday was aimed at providing relevant insights and recommendations while the FDA conducts its evaluation of pulse oximeters’ accuracy and overall performance.
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.

The accuracy of pulse oximeters for people with dark skin tones is now being reviewed. An FDA advisory panel met Friday to talk about how to make these devices more accurate for people with darker ...
Story at a glance New research sheds light on the widespread discrepancies of pulse oximeter accuracy among patients of color. The devices are used in both veterans and commercial hospitals.
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 first commercially available oximeters were produced by Hewlett-Packard, and were large, cumbersome, and expensive. These devices were of limited value because they were largely focused on research in the respiratory care field. Biox introduced the first pulse oximeter to commercial distribution in 1980. [4]
