WebOct 13, 2024 · The initial compensatory mechanism performed by the cardiovascular system is increasing the flow rate of blood throughout the system. This is best achieved by increasing the heart rate. Infections Infections often times illicit an inflammatory response in an immunocompetent host. 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.

WebPreload is, in simplest terms, the stretching of ventricles. Ventricles tend to stretch (fill with blood) and squeeze (push out blood) to distribute blood adequately. However, if too much pressure is backed up due to cardiac issues, the ventricles tend to stretch extensively, taking longer to squeeze, resulting in an abnormal contraction.
