Pulse oximeter inaccuracy due to darker skin tones was found in 30 out of 44 studies. Some studies showed a relationship between reduced oxygen saturation and overestimation bias. Among ...

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.

Dr Martin J Tobin discusses health disparities related to pulse oximeter accuracy and the need for improvement to make health care equitable.

T he differences, or bias, between estimates of blood oxygen saturation levels as measured with pulse oximeters compared to the gold-standard method of measuring oxygen saturation in arterial ...

Many chronic health conditions require you to measure your blood oxygen level at home by using a pulse oximeter.

However, the results also showed that pulse oximeters overestimated oxygen saturation, showing a positive bias in 20% of observations, and the proportion of observations with positive bias ...

Pulse oximeters underestimated blood oxygen levels ... direction meaning that someone might have dangerously low oxygen saturation that is not detected with a non-invasive monitor — was higher ...

A pulse oximeter works by using a beam of light to detect oxygen carried in red blood cells after being attached to the tip of the finger or ear. It provides a reading of the oxygen saturation ...

Pulse oximeters work by sending light beams through someone’s finger to estimate the oxygen saturation of their blood and their pulse rate. Ongoing research has found that if these devices are ...

Racial disparities in care among hospital patients may be tied to inaccuracies in pulse oximeter readings, a new study found. The research, led by a team from Brigham and Women’s Hospital and ...
