Front

How Cardiac Output is measured

Back

Cardiac Output = Heart Rate x Stroke Volume

Front

Stroke Volume (SV)

Back

The volume of blood ejected by each ventricle during each contraction (systole)

Front

Cardiac Output (CO)

Back

The volume of blood pumped through each ventricle per minute

Front

Systole

Back

heart muscle contracting

Front

Diastole

Back

heart muscle relaxing
