She is a co-author of a study published in 2024 that found unreliable pulse oximeter readings might limit the way Black patients with heart failure qualify for those potentially lifesaving procedures.
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.
health worker uses a pulse oximeter to check the oxygen saturation level , Jan. 21, 2021 The accuracy of pulse oximeters for people with dark skin tones is now being reviewed.
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.

Conventional pulse oximetry assumes that arterial blood is the only blood moving (pulsating) in the measurement site. However, during patient motion, the venous blood also moves, which can cause conventional pulse oximetry to under-read SpO 2 levels because it cannot distinguish between the arterial and venous blood.

He led the team of pulse oximeter engineers which later developed the Ohmeda Biox 3700 [3] which was widely used in the anesthesia market in the mid-1980s. 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 ...
