Observational StudyRegional oxygen saturation measured by two different oximetry monitors in infants and children undergoing living donor liver transplantation with bilirubin measurements: A prospective observational study.
Tissue oximetry devices use wavelengths in the 680-870 nm range to separate between oxygenated/deoxygenated hemoglobin. Conjugated bilirubin has an absorption peak at 730 nm. ⋯ Oximetry devices emitting light at >2 wavelengths may overcome interference from hyperbilirubinemia providing higher rSO2 readings.
