Pulse Oximetry: What Impacts Accuracy

SUMMARY:
Pulse oximetry is a standard tool in healthcare, yet research has revealed that its accuracy may be compromised in patients with darker skin tones. This segment reviews how pulse oximeters function, why light absorption is critical, and how skin pigmentation can interfere with readings. Listeners will gain insight into the clinical impact of occult hypoxemia, the historical oversight in device validation, and how these inaccuracies contribute to health disparities. Scientific findings and expert perspectives highlight the urgent need for awareness and reform.

Solutions to bias in pulse oximetry require collaboration between clinicians, manufacturers, and regulatory bodies. This segment presents practical strategies for healthcare professionals to identify and address inaccuracies in oxygen saturation readings. It also discusses advancements in device technology, the need for updated FDA oversight, and broader efforts to eliminate algorithmic bias in healthcare tools. Emphasis is placed on advocacy, inclusive design, and the role of providers in promoting equitable care.
