Shunt fraction interpretation

WebUnfortunately, shunt fraction was not calculated and mixed venous oxygen saturation was not measured, thus making interpretation difficult. One explanation may be that oxygenation during OLV depends not only on the magnitude of shunt fraction but also on the oxygenation of the shunted blood 69 ( fig. 4 ). WebIn normal subjects the regurgitant fraction was 0.7 ± 6.1%. In patients with mild, moderate and severe mitral regurgitation, the regurgitant fraction was 3.1 ± 3.4%, 24.5 ± 8.9% and 48.6 ± 7.6%, respectively. The regurgitant fraction correlated well with the echocardiographic severity of mitral regurgitation (r = 0.87).
