primary function of cardiac output and systemic vascular resistance Blood Pressure Arterial BP = Cardiac Output (CO) x Systemic vascular resistance (SVR) Cardiac Output = stroke volume x beats per min Systemic vascular resistance = force opposing the movement of blood within the blood vessels What ...

In congestive heart failure, cardiac output is decreased following reduced stroke volume, though there is an increase in total circulatory blood volume. Low cardiac output could promote a decrease in "effective circulatory blood volume", and impairs the sensitivity of baroreceptors. A reduction in ...
