Barker and Wilson analyzed Masimo laboratory data obtained from self-identified Black and White volunteer subjects to evaluate differences in Masimo pulse oximetry accuracy and bias on the basis of skin tone.
Key Points:
- Barker and Wilson analyzed Masimo laboratory data obtained from self-identified Black and White volunteer subjects to evaluate differences in Masimo pulse oximetry accuracy and bias on the basis of skin tone.
- To that end, they abstracted Pi values from their dataset, and divided them into “low perfusion” (Pi ≤ 1) and “normal perfusion” (Pi > 1) groups.
- For the subset of Black subjects, there was bias and precision of -0.26% ± 1.37%, and for White subjects, -0.12% ± 1.31%.
- In the low perfusion group, there was overall bias and precision of 0.48% ± 1.59%, with accuracy of 1.64% ARMS.
