Shunt fraction interpretation
WebOct 29, 2024 · The A-a gradient subtracts the PaO 2 from the result of the Alveolar Gas Equation (PAO 2):. PAO 2 – PaO 2 = P(A-a)O 2 (mmHg). The PAO 2 calculation is an estimated value using the following equation:. PAO2 = FiO 2 (PB-PH 2 O) – PaCO 2 /RQ. FiO 2 = concentration of oxygen the patient is breathing. PB = barometric pressure (usually … Weblarge shunt fractions were slightly more common in HCC group. In diffuse injections, most of the shunt fractions were concentrated between 0 and 5%, but with a long tail to the right. In more selective injections, most were concentrated between 0 and 10%. There was a trend for overall higher median shunt fraction in the diffuse mapping
