Description

FShunt is an estimate of the fraction of the venous return that bypasses the pulmonary circulation and/or is not oxygenated during passage through the pulmonary capillaries (pc), that is, the ratio between the shunted cardiac output and the total cardiac output:

FShunt = (ctO2[pc] - ctO2[a])/(ctO2[pc] - ctO2[v]) where [pc]= pulmonary capillaries, [a] = arterial blood, [v] = mixed venous blood

If no mixed venous sample is measured, FShunt is estimated by assuming the arteriovenous difference to be 2.3 mmol/L.

In the absence of extrapulmonal shunting, FShunt provides information about the intrapulmonary component of hypoxemia. A high FShunt indicates pathological pulmonary mismatch between ventilation and perfusion, e.g., perfusion of non-ventilated areas (atelectases) and/or increased ventilation-perfusion scatter.
