WebIf that happens, blood flow by-pass of the systemic circulation through the arterial duct results in pulmonary overflow and systemic hypoperfusion. When pulmonary flow is 50% higher than systemic flow, a hemodynamic "paradox" results, with an increase of left ventricular output without a subsequent increase of systemic output. WebUseful Hemodynamic Formulas 1. Calculation of Blood Flow Q = P/R Q = V × A(orQ= V × ×r2) Where: Q = blood flow P = Pressure gradient = pressure proximal – pressure …
