Fingertip monitors known as pulse oximeters that can be used at home to detect low blood oxygen levels (hypoxaemia) give higher readings for patients with darker than lighter skin tones, finds the ...

Serious hidden hypoxemia — defined as an SaO2 less than 88% despite an SpO2 of 92% or greater — occurred in 0.6% of the critically ill Asian patients studied. Hypoxemia went undetected in 0.8% of ...

A total of 11,018 paired SpO2-SaO2 measurements were analysed. All five pulse oximeters returned higher SpO2 values for patients with darker skin tones than patients with lighter skin tones, at any ...

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 ...
