Summary

This study will check if pulse oximeters, which measure oxygen levels in the blood, are as accurate in dark-skinned children as in lighter-skinned children. About 540 children aged 2-9 undergoing anesthesia will have their pulse oximeter readings compared to a more precise blood test. The goal is to see if skin color affects the device's performance.
