In the PAPI score formula, what does 'sPAP' represent?

In the PAPI score formula, 'sPAP' refers to Systolic Pulmonary Artery Pressure. This measurement is critical in evaluating a patient's hemodynamics, particularly in cases of cardiac and pulmonary function assessment. The sPAP is the pressure in the pulmonary artery during the contraction of the heart, which provides insights into the right ventricular function and the overall cardiovascular status of a patient.

Understanding sPAP is vital in the context of ECMO, as it can indicate how well the heart is functioning and whether there is adequate blood flow and oxygenation to meet the body's needs. Monitoring sPAP helps clinicians make decisions regarding the management of ECMO support, ensuring that any underlying pulmonary or cardiac issues are adequately addressed.
