Defined as: The
volume pumped by each ventricles per minute.
- Can also be written as the stroke
volume x heart rate where stroke
volume is the volume pumped by each
ventricle.
Factors determining Cardiac
Output (CO).
Volume of the cardiac output determined
by 2 factors:
- Permissive pumping
capacity of the heart: the maximum
volume which the ventricle can pump per minute.
- Venous
return: the volume of blood entering the
right atrium per minute.
Changes in any of these
two factors, would influence the cardiac output.
