There’s a growing consensus among physicians and government regulators that pulse oximeters measure oxygen levels less accurately in patients with darker skin and need to be fixed. There’s ...

The Food and Drug Administration's recommendations apply to pulse oximeters, which are clip-on devices used in hospitals and medical clinics to ensure patients are getting enough oxygen.

Pulse oximeters routinely overestimated levels of oxygen in the blood in darker-skinned ... The issue has already led to reviews by federal regulators, with some efforts underway to determine ...

Blood oxygen measurements taken with pulse oximeters in hospitals tend ... and the study’s first author. Regulators set standards that capture overestimation, underestimation, and precision ...

The regulator said the guidance, if finalized, would apply to oxygen monitoring devices known as pulse oximeters that are used for medical purposes. Pilot project monitors patients while they ...

A clear pattern emerged. The pulse oximeters, those small clips that doctors and nurses rely on to monitor blood oxygen, weren’t giving everyone the same quality of information. In some patients ...

Pulse oximeters clip on to a person’s finger and use two wavelengths of light sent into the skin to quickly estimate how much oxygen is flowing through the blood based on how much light is absorbed.

It’s not an easy problem to fix, and pulse oximeters are overall a less precise measure of oxygen in the blood. But hospitals and regulators should push to only allow devices that perform the ...

A pulse oximeter measures your blood oxygen levels and pulse. A low level of oxygen saturation may occur if you have certain health conditions. Your skin tone may also affect your reading.

There are two types of tests used to measure blood oxygen levels: pulse oximeter and arterial blood gas (ABG). A pulse oximeter may be used at home or at a medical office. ABG, while very accurate ...
