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 ). WebSep 1, 2001 · Using a similar approach, the shunt fraction can be estimated when the P a O 2 < 100 Torr and the Pa O 2 lies between 50 and 100 Torr. In this case, Eq. 10 becomes . 10A. Equations 10 and 10A are only estimates of shunt fraction and are insensitive to larger gradients in the denominator of Eq. 5.
