How to Use the Pulmonary Flow Calculator
- Enter the Cardiac Output in liters per minute (L/min). This is the total volume of blood being pumped by the heart per minute.
- Enter the Pulmonary Vascular Resistance in Wood Units. This measures the resistance offered by the pulmonary vasculature.
- Click the Calculate button to compute the pulmonary flow.
- The result, pulmonary flow in liters per minute (L/min), will be displayed in the Pulmonary Flow field.
Understanding the Formula
The pulmonary flow (Qp) is calculated by dividing the cardiac output (CO) by the pulmonary vascular resistance (PVR). The formula is:
Qp = CO / PVR
Where:
- Qp = Pulmonary Flow (L/min)
- CO = Cardiac Output (L/min)
- PVR = Pulmonary Vascular Resistance (Wood Units)
