Enter the pulmonary physiologic shunt (mL/min) and the cardiac output (mL/min) into the Shunt Equation Ratio Calculator. The calculator will evaluate the Shunt Equation Ratio.

## Shunt Equation Ratio Formula

The following two example problems outline the steps and information needed to calculate the Shunt Equation Ratio.

**SE = Qs / Qt**

Variables:

- SE is the Shunt Equation Ratio ( )
- Qs is the pulmonary physiologic shunt (mL/min)
- Qt is the cardiac output (mL/min)

## How to Calculate Shunt Equation Ratio?

The following steps outline how to calculate the Shunt Equation Ratio.

- First, determine the pulmonary physiologic shunt (mL/min).
- Next, determine the cardiac output (mL/min).
- Next, gather the formula from above = SE = Qs / Qt.
- Finally, calculate the Shunt Equation Ratio.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

pulmonary physiologic shunt (mL/min) = 14.75

cardiac output (mL/min) = 16..00

SE = Qs / Qt** **= ?
