No : Ef is the percentage of blood ejected with each heart beat. >55% is normal. Cardiac output is the amount of blood in ccs or milliliters ejected per minute and is dependent on heart rate and stroke volume (the volume of blood pumped in a single beat) co depends on body size but a typical measurement is in the range of 5 liters per minute.

Related but not the : Same. Co is a mathematical calculation of the amount of blood pump by the left ventricle of your heart in one minute ( stroke volume x hr ). The ejection fraction is a measurement of the percentage of blood leaving your left ventricle every time contract. Can be measure by 2d echocardiogram, cardiac catheterization, nuclear scan, mri. Hope it help.

Heart pump volume: The cardiac output is the volume of blood per minute pumped by the heart. Cardiac output is equal to heart rate multiplied by stroke volume (the volume of blood ejected with each heartbeat).
