A pulse oximeter measures your blood oxygen levels and pulse. A low level of oxygen saturation may occur if you have certain health conditions. Your skin tone may also affect your reading.

Black people in the hospital are 31.9% more likely than White patients to have pulse oximeter readings that overestimate their oxygen levels by at least 4 percentage points, according to data ...

1). As highlighted by the COVID-19 pandemic, accurate pulse-oximeter readings can be crucial for clinical decisions, especially when arterial blood-gas tests — the gold standard for determining ...

The study also answered critics who had said differences in oxygen levels might occur because blood draws in previous comparisons had been made 10 minutes after pulse oximeter readings ...

As a result, patients with darker skin tones are more likely to get pulse oximeter readings that show their blood oxygen saturation to be higher than it actually is. As early as 1990, researchers ...
