The 2 minute update looks at a study asking if a patient’s skin color affects the accuracy of pulse oximeter readings?
In this study, over 10,000 patients had pulse ox measurements and ABGs drawn within 10 minutes of each other
About 12.5% of the patients were Black
Patients with diabetes or elevated carboxyhemoglobin levels were excluded
00:37
When pulse ox saturation showed 92-96%, 11.7% of Black patients actually had oxygen saturation under 88% on ABGs, which is more than triple the rate seen for White patients, at only 3.6%
00:58
When pulse ox sats were 89-96%, ABGs for Black patients showed oxygen saturation about 1.5% lower than those for White patients.
Which begs the question: do we need different pulse ox devices based on skin color?
01:16
It also makes one wonder if we should have different thresholds for ordering ABGs based on skin color? Conversely, should we rely more on clinical evaluation than pulse ox readings?
