Pulse Oximetry Accuracy by Skin Color

This is a prospective, non-randomized, non-blinded comparative study to evaluate the accuracy of pulse oximetry compared to co-oximetry in dark-skinned (Black) compared to lighter-skinned (White) children undergoing anesthesia, using standard FDA performance statistics as measured by mean bias and accuracy root mean squared to evaluate device performance.

Inclusion Criteria:Children aged 2-9 years undergoing general anesthesia with or without arterial line placement.Exclusion Criteria:Patients with cyanotic congenital heart disease.Patients with bleeding disorders.Patients taking blood thinners.
