Oxyhemoglobin arterial
WebMar 4, 2024 · Pulse oximetry measures peripheral arterial oxygen saturation (SpO 2) as a surrogate marker for tissue oxygenation. It has become the standard for continuous, noninvasive assessment of oxygenation and is often considered the "fifth vital sign" [ 1-3 ]. Theoretical and clinical aspects of pulse oximetry will be reviewed here. WebOct 8, 2024 · Blood in the systemic arteries, at a PO2 of 100 mmHg, has apercent oxyhemoglobin saturation of 97% (which means that 97% of the hemoglobin is in the form of oxyhemoglobin).
