Summary

This study aims to see how well pulse oximeters measure oxygen levels compared to the gold standard—blood samples. Researchers will enroll 20 healthy adults, including people with dark skin, to check if skin tone affects accuracy. Participants will breathe different oxygen mixtures while their oxygen levels are measured by both a pulse oximeter and an arterial blood test.
