For the study, researchers compared pulse oximeter readings with functional oxygen saturation from blood gas analysis, a gold-standard blood test for oxygen saturation.

Pulse oximeters are widely used in hospitals and clinics to monitor blood oxygen levels. These small, noninvasive devices ...

Black people in the hospital are 31.9% more likely than White patients to have pulse oximeter readings that overestimate their oxygen levels by at least 4 percentage points, according to data ...

If you have a health condition, your blood oxygen level may fall outside of the normal range. Learn what abnormal blood oxygen levels mean.

Learn about the pulse oximetry test, which measures your blood oxygen levels. Know the importance, how it’s performed, and what the results mean for your health.

Pulse oximeters measuring oxygen in the blood often inflated the levels for dark-skinned Covid patients, who then experienced delayed care or an increased risk of hospital readmission, researchers ...

How Does a Pulse Oximeter Work? A pulse oximeter, also called a pulse ox, is a device that measures oxygen saturation levels, or O2 sat, in your blood.

The pulse oximeter may sometimes inaccurately show a patient’s blood oxygen level reading to be much higher than 88 per cent, and that can lead to a 'delay in potentially life-saving treatment ...

Checking or monitoring blood oxygen levels is non-invasive and doesn't hurt. There are no known risks or dangers of using a pulse oximeter to measure your blood oxygen level.

Pulse oximeters are used to check blood oxygen saturation levels and heart rate. Research suggests that these devices may be less accurate for people with darker skin pigmentation.

The researchers found that 24.7% of Black patients had pulse oximeter readings that were at least 5 percentage points higher than the oxygen levels in their blood gas results.
