Abstract: Arterial oxygen saturation (SpO2) is a non-invasive indicator used to assess the oxygen-carrying capacity of the blood and is widely utilized in conditions such as respiratory failure and hypoxemia.Conventional measurement sites, such as the fingertip and earlobe, have limitations, and nasal measurement has recently gained attention.This study compared the response speed and signal stability between nasal, fingertip, and earlobe measurements using the latest Nasal Alar SpO₂ sensor.The nasal measurement demonstrated stable perfusion index (PI) values and rapid response, proving to be useful even in low perfusion states.
