Shock syndromes are of three types namely cardiogenic, hemorrhagic and inflammatory. They differ in physiological and pathological pathways and clinical presentations. The Management also differs considerably. In hemorrhagic shock there is a failure of the peripheral circulation that has its initial deranged variables in the blood volume and venous return while in cardiogenic Shock there is primary pump failure where the cardiac output/mean arterial pressure are deranged. Contrary to this in Inflammatory Shock the microcirculation is affected while the initial deranged macrocirculation variable is the total peripheral resistance hit by systemic inflammatory response. various toxins and pathways play a role in these differing presentations. In the article below an effort has been made to understand the Physiology and Pathology behind different types of shocks.
