Web4 mrt. 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. WebThis can be determined by measuring a central venous blood sample away from the ECMO cannulas (e.g. the left internal jugular vein) and comparing it to the pre-membrane blood sample. If there is a significant difference in the PO2 of these quantities, then recirculation should be suspected.
