Racial discrepancy in pulse oximeter accuracy in preterm infants.

Objective: Pulse oximetry is commonly used in Neonatology, however recent adult data suggest racial disparity in accuracy, with overestimation of oxygen saturation for Black patients.

Study Design: Black and White infants <32 weeks gestation underwent simultaneous arterial blood gas and pulse oximetry measurement. Error by race was examined using mean bias, A, Bland-Altman, and linear/non-linear analysis.
