Understanding Shock: Types, Classification, and Clinical Course
Shock is a critical state where the circulatory system fails to adequately perfuse cells, leading to oxygen and nutrient delivery reduction. It can be classified into hypovolemic, cardiogenic, and distributive types, with septic shock caused by microbial infections. Shock progresses through stages from initial compensatory mechanisms to irreversible organ damage. Organs are severely affected in septic shock, leading to widespread tissue hypoperfusion. Clinical manifestations of shock include weak pulse, rapid heart rate, tachypnea, cool clammy skin, and cyanosis.
