Shock, also known as Inadequate Tissue Perfusion, is a life-threatening condition that occurs as a result of the disruption to 3 major components of the cardiovascular system: Heart Function, Blood Vessel Function, and Blood Volume. Perfusion describes the process of adequate blood flow to the organs, where the waste and reactants that are involved in cellular respiration are removed or transported throughout the 3 parts of the cardiovascular system for metabolism to be processed effectively. However, if one part were to fail, important resources for cellular respiration such as oxygen would not be able to reach the organs that needs it function. In an attempt to compensate, the body would divert blood to organs that cannot tolerate the lack of blood, such as the heart and the brain, resulting in widespread vasoconstriction, or thinning of the blood vessels. Consequently, blood is prevented from reaching organs that can tolerate the lack of perfusion, or hypo perfusion, in organs such as the skin, resulting in the typical presentation of pale and clammy skin conditions during shock. Moreover, disruptions may present specifically to each component or multiple systems may be affected at the same time, which generally results in the 3 designated types of shock: Obstructive, Distributive, Hypovolemic. Typically, patients would have a presentation of shock at the Compensated, Decompensated, and Irreversible Stage.
