A major UK study shows that commonly used home pulse oximeters can overestimate oxygen levels in people with darker skin, increasing the risk of undetected hypoxemia and raising urgent questions about ...

Pulse oximeters that can be used at home to detect hypoxaemia give higher readings for patients with darker than lighter skin tones, according to UK researchers. As a result, they warn that low blood ...

In the EXAKT study from the U.K., the home-use pulse oximeters assessed all gave higher oxygen saturation (SpO2) readings for patients with darker skin tones than for patients with lighter skin tones.

Objectives To assess the impact of skin tone on the measurement and diagnostic accuracy of five fingertip pulse oximeters used by patients in the NHS (National Health Service) England COVID Oximetry ...

Abstract: This paper proposes a novel mathematical model that quantitatively defines the relationships between the arterial oxygen saturation (SaO2), the arterial partial pressure of oxygen (PaO2) and ...

A research team from the University of Oxford conducted hypoxemia detection and sleep monitoring using the Viatom Checkme O2+ wrist oximeter on 50 hospitalized SDB patients. Checkme O2+ turned out to ...

The OpenOximetry Dataset stores clinical and lab pulse oximetry data. It supports measurements of arterial oxygen saturation (SaO2) by arterial blood gas co-oximetry and pulse oximetry (SpO2), ...

The EquiOx study showed that in critically ill patients, oxygen saturation assessed by pulse oximetry (SpO 2) was often lower than arterial oxygen saturation (SaO 2 ...

Discrepancies between pulse oximetry and arterial oxygen saturation can pose challenges in clinical assessment. Possible underlying causes include poor peripheral perfusion, skin pigmentation, motion ...

Chronic obstructive pulmonary disease (COPD) is globally the third leading cause of death, causing 3.23 million deaths in 2019. Most feasible way to measure oxygen saturation is by pulse oximetry ...

SpO2 overestimated SaO2 by 0.93% in Black patients, 0.49% in Hispanic patients, and 0.53% in patients of other racial/ethnic groups compared with White patients. Overestimation of O 2 saturation based ...
