Two studies suggest both under- and over-estimation of blood oxygen levels ...

By Dr. Liji Thomas, MD A major UK study shows that commonly used home pulse oximeters can overestimate oxygen levels in ...

Fingertip monitors known as pulse oximeters that can be used at home to detect low blood oxygen levels (hypoxaemia) give higher readings for patients with darker than lighter skin tones, finds the ...

A Food and Drug Administration (FDA) draft guidance would require manufacturers of pulse oximeters to gather far more clinical data to show the devices accurately work across a range of skin tones.

Fingertip monitors known as pulse oximeters that can be used at home to detect low blood oxygen levels (hypoxemia) give higher readings for patients with darker than lighter skin tones, finds the ...

Pulse oximeters use light to measure how much oxygen is in a person’s blood. For most people, a normal pulse oximeter reading is between 95% and 100%, researchers said in background notes. Readings ...

Makers of medical devices that quickly measure oxygen levels in the blood would have to gather extra data to show that their products work for patients of color, under a new federal proposal released ...

Research confirms that skin pigmentation can reduce the accuracy of pulse oximeters. Researchers found that red light, a key component in pulse oximetry, is more strongly attenuated in pigmented skin.

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 ...
