New research reveals that pulse oximeters can reduce color accuracy

New research raises questions about the accuracy of pulse oximeters for some people of color. These devices are not tuned for dark skin, so there is a risk of overestimating oxygen saturation in Asian, black, and Latin patients.

Inaccurate measurements can result in people in colors who are not receiving the necessary oxygen supplements or are prescribed COVID-19 treatments such as antivirals. Remdesivir Or steroids Dexamethasone..

Leading author of a new study published in American Medical Association Internal Medicine Online JournalAn analysis of pre-pandemic health data researchers told the NPR that pulse oximetry measurements resulted in patients with colors receiving less oxygen supplementation than Caucasian patients.

“We were fooled by the pulse oximeter,” said Dr. Leo Anthony Seri, lead author of the study, clinical research director and principal investigator at the MIT Institute for Computational Physiology.

“The patients were given the false impression that they were okay, and what we showed in this study was that they were giving them less oxygen than they needed.” He told NPR.

In a study of 3,069 patients in the intensive care unit, Asian, black, and Hispanic patients had higher adjusted time-weighted mean pulse oximetry readings and specific mean hemoglobin oxygen compared to Caucasian patients. It was found that the amount of oxygen supplemented was significantly lower than the saturation level.

“There are differences in oxygen supplementation between Asian, black, Hispanic and Caucasian patients that may contribute to racial and ethnic disparities in care related to pulse oximeter performance. “I did,” the study said.

“Further research is needed to confirm these findings and investigate other clinical factors associated with treatment disparities,” he continued.

Pulse oximetry is a painless, non-invasive measurement method. Oxygen saturation in human blood. Oxygen saturation indicates how well your lungs are functioning.

Pulse oximeters played an even more important role in hospitals and homes during the COVID-19 pandemic.

Earlier this year KSL-TV ReportDr. Wing, an emergency physician and medical director at Intermountain Park City Hospital, recommended that Utahns get a home-use pulse oximeter if he becomes ill with COVID-19 symptoms.

“If your oxygen level is less than 90%, you need to go to the emergency department or call 911,” he said.

A new study reflects that pulse oximeters may be less accurate in patients of some colors, but healthcare providers can also draw blood to measure oxygen saturation, so the device It doesn’t just depend on it.
