Accurate pulse oximetry ‘challenging’ in critically ill patients; skin pigmentation a factor
CHICAGO — In a new study, pulse oximeters underestimated arterial oxygen saturation among patients in the ICU, and the ability of the devices to detect hypoxemia was especially hindered in patients with dark skin pigmentation.
FDA releases draft guidance on pulse oximeter study recommendations
The FDA announced its draft guidance on recommendations for studies assessing pulse oximeters to ensure the devices perform similarly in individuals with different skin pigments, according to a press release.
Diversity in pulse oximeter clearance summaries increases after 2013 FDA guidance
Following the FDA’s release of a guidance requesting more diversity in pulse oximeter testing, the number of clearance summary documents discussing race and ethnicity/skin tone rose, according to a research letter published in JAMA.
Pulse oximeters overestimate oxygen saturation in darker skin pigments
Among individuals with darker skin tones, pulse oximeters often overestimated their oxygen saturation levels, according to a systematic review published in British Journal of Anaesthesia.
FDA panel: Proposed changes to pulse oximeter premarket studies generally well received
