WebHemoglobin fraction of total hemoglobin (fractional oxyhemoglobin) Definition. F O 2 Hb is defined as the ratio between the concentrations of O 2 Hb and tHb ( c O 2 Hb/ c tHb). It is calculated as follows: The systematic symbol for arterial blood is F O 2 Hb (a). The analyzer symbol may be O 2 Hb or F O 2 Hb. 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 ). t shirts long fitWebThere are two different ways that shunt fraction can be measured and calculated; physiological and anatomical.
