Retrospective cohort analysis examines pulse oximetry accuracy by race in hypoxemic children, suggesting caution in interpretation.

To confirm whether pulse oximetry accuracy differs by race in children with congenital heart disease.
Retrospective cohort analysis using a multicenter database of 1,700 hospitals.
Included children under 18 years with congenital heart disease and valid SpO2/SaO2 readings.
Used statistical tests (Wilcoxon rank-sum and chi-square) to analyze differences in SpO2-SaO2.
Excluded readings with SaO2 < 70% and children with multiple races.
Analyzed 22,512 SpO2/SaO2 readings from 9,301 encounters in 8,908 patients.
No significant differences in median SaO2 between black (96.0%) and white (96.2%) patients (p = 0.83).
SpO2-SaO2 differences increased with hypoxemia; 50.6% of white and 60.0% of black patients had differences ≥5% when SaO2 was 80-84% (p < 0.001).

Fountaine et al. (2026) studied this question.
