WebJun 26, 2016 · Shunt Detection and Quantification William Grossman Mauro Moscucci Detection, localization, and quantification of intracardiac shunts are an integral part of the hemodynamic evaluation of patients with congenital heart disease. In most cases, an intracardiac shunt is suspected on the basis of the clinical evaluation of the patient before … WebThe numerator of the shunt equation is represented by differences in C c O 2 and C a O 2. The denominator of the equation is represented by the differences in C c O 2 and C v O 2. Changes of unequal magnitude among these three levels will change the ratio, which is equivalent to changes in the physiologic shunt calculation. raytheon mmis
