Blood oxygen measurements taken with pulse oximeters in hospitals tend to be lower than they really are, according to the Equiox study, which was designed to assess the technology’s measurement ...

A Food and Drug Administration advisory committee met Friday to figure out ways to make pulse oximeters more accurate when doing readings on darker skin both in hospitals and at home, after research ...

A recent study found that a key tool for reading blood oxygen can give inaccurate readings for Black and Hispanic patients. Pulse oximeters are placed on a person’s finger and can help monitor how ...

Oakland, California — 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 ...

Pulse oximeter devices routinely overestimate blood oxygen levels in darker-skinned patients—a racial bias that can trigger downstream health harms for Black individuals, compounding well beyond any ...

Early on in the COVID-19 pandemic, Kimani Toussant’s wife, an epidemiologist, brought him an article about how pulse oximeters appeared to be less accurate in people with darker skin. The small ...

The researchers then compared pulse oximetry blood oxygen values (SpO2) with "gold-standard" arterial blood gas measurements (SaO2). SpO2 values were assessed at two thresholds in line with current ...

Dr. Takuo Aoyagi, a Japanese bioengineer, was the first to invent pulse oximetry in 1974. 2 The pulse oximeter is based on the light absorption characteristics of hemoglobin at different wavelengths.

A portable device used to detect blood oxygen levels revolutionized the medical field 50 years ago and is now receiving essential updates Efforts to improve the accuracy of pulse oximetry readings for ...

As part of routine care in our six-hospital health system (which includes more than 500 outpatient practices), adults in our electronic health record with Covid-19 infection — as determined by their ...

If you’ve ever had a medical team investigating cardiac issues, you’ve probably had a bunch of electrodes stuck all over your chest and been hooked up to an electrocardiogram. This is the gold ...
