Evaluating Handheld Pulse Oximeter Accuracy Across Diverse Skin Tones

Nonin CO-Pilot™ and PalmSAT ® 2500 Series meet FDA standards, delivering accurate readings and outperforming competitors

In 2024, the Open Oximetry Project conducted an evaluation of handheld pulse oximeters, including the Nonin CO-Pilot™ and the Nonin PalmSAT® 2500 Series. The assessment aimed to determine the accuracy of these devices across patients with varying skin tones, including those with darker pigmentation. This effort addresses longstanding concerns about pulse oximeter performance for individuals with darker skin, as studies have shown that inaccuracies in oxygen saturation readings for patients of color contributed to delayed treatment and adverse outcomes during the COVID-19 pandemic.1

Pulse oximeters have historically shown discrepancies in their readings for individuals with dark skin pigmentation.2 With these issues gaining more attention in recent years, the Open Oximetry Project was established…
