Jan 7, 2021 WEDNESDAY, Jan. 6, 2021 (HealthDay News) — Black patients have higher frequency of occult hypoxemia that is not detected by pulse oximetry, according to a research letter published in the Dec. 17 issue of the New England Journal of Medicine. Michael W. Sjoding, M.D., from the University of Michigan Medical School in Ann Arbor, and colleagues examined potential racial bias in pulse oximetry measurements in a study involving adult inpatients receiving supplemental oxygen. A total of 10,789 pairs of measures of oxygen saturation by pulse oximetry and arterial oxygen saturation in ...

Punch Newspapers Sections A new study published in the New England Journal of Medicine says pulse oximeter results are three times likely to give misleading results in patients with black skin. A pulse oximeter is a small device attached to the thumb which tells healthcare workers a person’s level of blood oxygenation. A pulse oximeter works by a process that senses the level of oxygen in the blood by passing light through the skin. It’s thought that the wrong result in black skin could be because darker skin pigments absorb light differently. Since the COVID-19 pandemic, there has been ...

Pulse Oximeters Can Give Inaccurate Results to People With Dark Skin, a Study Found—Here's What to Know Health.com 12/18/2020 Claire Gillespie If you have a heart or lung condition, you might be familiar with a pulse oximeter—a small, rectangular device that clips onto your finger and reads your blood oxygen and heart rate. During the COVID-19 pandemic, many people have invested in an oximeter, because an abnormal blood oxygen or heart rate could possibly signal a respiratory issue that might be linked to the coronavirus. But a pulse oximeter may not suitable for everybo...

If you have a heart or lung condition, you might be familiar with a pulse oximeter—a small, rectangular device that clips onto your finger and reads your blood oxygen and heart rate. During the COVID-19 pandemic, many people have invested in an oximeter, because an abnormal blood oxygen or heart rate could possibly signal a respiratory issue that might be linked to the coronavirus.

New England Journal of Medicine suggests that pulse oximeters – frequently used in remote patient monitoring – may show misleading readings for Black patients.   Researchers led by Dr. Michael W. Sjoding at the University of Michigan Medical School compared measurements of arterial oxygen saturation with pulse oximetry. They found that in two large cohorts Black patients had nearly three times the frequency of occult hypoxemia – meaning there was a disconnect between their arterial oxygen saturation and their pulse oximetry – compared to white patients.   "Given the widespread use ...
