The connection between how much blood the heart pumps (cardiac output or CO) and the average pressure in our arteries (mean arterial pressure or MAP) is pretty simple for healthy people.
Cardiac Output (CO): This means how much blood the heart moves in one minute.
Mean Arterial Pressure (MAP): This shows the average pressure in our arteries during one heartbeat cycle.
The formula that links these two is:
MAP ≈ CO × SVR
Here, SVR stands for systemic vascular resistance, which means how hard it is for the blood to flow through the blood vessels.
So, when the heart pumps more blood (higher cardiac output), the mean arterial pressure usually goes up as long as the resistance doesn’t change.
For example, when you exercise, your heart pumps more blood. You can feel your blood pressure increase during that time.
