WebCardiac preload is one of the main factors that influence how much blood the heart pumps out with each heartbeat, or stroke.. Now, remember that the heart has two upper chambers: the left atrium, which receives oxygenated blood from the lungs via the pulmonary veins; and the right atrium, which receives deoxygenated blood from all of our organs and tissues via … WebFeb 20, 2024 · It does cause venoconstriction, which may increase preload. Its dominant effect on cardiac output is often to cause a reduction (but this may depend on the heart's ability to tolerate increased afterload). Clinical use: Vasodilatory shock (particularly sepsis). Typically given in low doses (0-0.06 U/min), either as primary or secondary agent. fermax intercom systems
