How does cardiac output affect blood flow
WebIncreased cardiac output is the main haemodynamic factor, mediated by lower afterload, increased preload, and positive inotropic and chronotropic effects. Decreased afterload is due to vasodilatation and reduced vascular resistance as a consequence of lower blood viscosity, hypoxia-induced vasodilatation, and enhanced nitric oxide activity. WebThe decrease in the amount of blood that is pumped out of the heart into the veins has a significant impact on the body's total cardiac output. The total volume of blood that is pumped out of the heart in one minute is referred to as the cardiac output. This output is determined by two primary factors: the stroke volume (SV) and the heart rate ...
