DO Students Discover Racial Discrepancies in Pulse Oximetry ReadingsOctober 27, 2022
Seven PCOM South Georgia students are raising awareness of the disparities that marginalized patients face
when using pulse oximetry technology.
Tori Gooden (DO ‘25), Justice Dove (DO ‘25), Dana-Marie Gould (DO ‘25), Lola Sewo
(DO ‘25), Anthony Dove (DO ‘25), Laurie’l Latimer (DO ‘25) and DeStandreana Norwood
(DO ‘25) were all inspired to pursue research as the topic aligns with their passions
of bringing awareness to health disparities and how they affect patient outcomes.
The group sought out to investigate how racial discrepancies in pulse oximetry readings
among self-monitoring devices affect Black patients.
Recent studies have found discrepancies in pulse oximeter readings among Black patients,
posing a problem for both patients and their providers. According to their studies,
current pulse oximetry technology is not able to accurately evaluate oxygen saturation
in patients with darker skin tones when oxygenation is truly low.
“Since pulse oximetry is an essential evaluation tool for medical care, we knew it
was imperative to not only provide awareness for this problem but to also search for
possible solutions to help improve these disproportionate health disparities,” said
Latimer (DO ‘25).
The students’ research found that pulse oximetry technology does not provide values
that accurately represent hypoxic levels in Black patients, and a standard pulse oximetry
device using only two-wavelength finger pulse on darker skin tones leads to decreased
“With this project we hope to not only bring awareness to these health discrepancies
and their affect on patient outcomes, but also hope to show current data that supports
how these discrepancies are related to current health disparities such as COVID,” Gould said.
The medical students’ research highlighted the need for accuracy in pulse oximetry readings, stating that
inaccuracies can lead to delayed medical treatment, which leads to costly impacts
and potentially poor outcomes for patients.
“This research makes people aware of the fact that people with darker skin are more
likely to have discrepancies in their pulse oximetry readings,” Sewo said. “This discrepancy
is not readily known in the healthcare profession, so the potential for patient harm
can be increased unknowingly for minorities. Our research can also be used to implore
pulse oximetry manufacturers and other companies that produce medical equipment to
design new products that can be used to help improve patient outcomes.”
