Racial Bias in Pulse Oximeters

Updated: Jan 12

Physicians use pulse oximeters to identify patients who need supplemental oxygen. Since this technology was developed using a racially non-diverse population, it should not be surprising that occult hypoxemia (undetected blood oxygen levels below 88%) was three times more likely in Black than White patients in two large cohorts. This Real Genius episode was drawn by Dani S@unclebelang and written by Fred Shaffer and Zachary Meehan. BioSource releases one new WEBTOON episode weekly to support science literacy.

We missed Bloom County and Calvin & Hobbes and wanted to provide a safe space of gentle humor and innocent fun.
