Apr 3, 2023 · Pulse oximetry can estimate the levels of oxygen in your blood. Find out how a pulse oximetry test works, what it's used for, and what the readings mean.
Pulse oximetry is a noninvasive method for monitoring blood oxygen saturation. Peripheral oxygen saturation (SpO 2) readings are typically within 2% accuracy (within 4% accuracy in 95% of cases) of the more accurate (and invasive) reading of arterial oxygen saturation (SaO 2) from arterial blood gas analysis.
