WebAs described elsewhere, cardiac output increases or decreases in response to changes in heart rate or stroke volume. When a person stands up, for example, cardiac output falls because a fall in central venous pressure leads to a decrease in stroke volume. As another example, limb movement (muscle pump) during exercise enhances venous return to the … toproyWebAortic and Arterial Pulse Pressure.
