An increased cardiac output, which is the amount of blood pumped by the heart per minute, causes an increase in both blood pressure (I) and oxygen delivery to tissues (II). It does not directly affect the systemic vascular resistance (IV), and may increase or decrease it depending on factors such as changes in blood viscosity or vessel diameter. It may also have an effect on venous return (III), but this is dependent on other factors such as blood volume and cardiac filling pressures.
