The differences, or bias, between estimates of blood oxygen saturation levels as measured with pulse oximeters compared to the gold-standard method of measuring oxygen saturation in arterial blood ...

For most people, a normal pulse oximeter reading is between 95% and 100%, with readings below 90-92% generally considered low and requiring medical attention. They are known to be affected by several ...

The patient was in his 60s, an African American man with emphysema. The oximeter placed on his fingertip registered well above the 88% blood oxygen saturation level that signals an urgent risk of ...

By Dr. Liji Thomas, MD A major UK study shows that commonly used home pulse oximeters can overestimate oxygen levels in people with darker skin, increasing the risk of undetected hypoxemia and raising ...

Reports of race, ethnicity, or skin tone occurred 320 times in 12.5% of 767 FDA summary documents that discussed pulse oximeter performance testing from 1996 to 2024, reported Kadija Ferryman, PhD, of ...

Pulse oximetry was less accurate for people with darker skin tones in two studies, one regarding home-use devices and the other hospital-grade devices, although with some surprising differences ...

OAKLAND, Calif. — The patient was in his 60s, an African American man with emphysema. The oximeter placed on his fingertip registered well above the 88% blood oxygen saturation level that signals an ...

In the EXAKT study from the U.K., the home-use pulse oximeters assessed all gave higher oxygen saturation (SpO2) readings for patients with darker skin tones than for patients with lighter skin tones.
