Qp:Qs Shunt Fraction ASD/VSD Calculator

Calculate pulmonary to systemic flow ratio from oxygen saturations to quantify intracardiac shunt magnitude in ASD and VSD

Each component has a specific meaning:

• Oxygen saturations — The oxygen saturations recorded for the scenario being assessed.

Note: Interpret the qp:qs shunt result against the thresholds and context described above.

Enter the oxygen saturations for the scenario you are assessing. Calculate pulmonary to systemic flow ratio from oxygen saturations to quantify intracardiac shunt magnitude in ASD and VSD. Use the qp:qs shunt result to inform your calculation.
