Melanin bias in pulse oximetry explained by light source spectral bandwidth
Study context
- Comparison
- Narrow vs Broad
- Outcome
- Effect of melanin content on the ratio of SpO2 readings for narrow and broad spectral bandwidths
Methodological detailsspectrally resolved photoplethysmography (srPPG), reduced inspired O2 concentration
- Spectrally resolved photoplethysmography (srPPG)
- Reduced inspired O2 concentration
Main finding
As reported in the abstract
SpO2 bias with melanin
- LED light emission spectra, as used in commercial pulse oximeters, give erroneously high SpO2 in patients with greater skin melanin than the calibration subject pool
