WVC 91st Annual Conference
Specialty Veterinary Technician Session: Shock has two faces. Shock is defined as an inadequate production of cellular energy, very commonly brought on through forms of circulatory failure. Hypovolemic (inadequate circulating blood volume), cardiogenic (inability for heart to create forward flow), distributive (loss of systemic vascular resistance), and obstructive (obstruction of large vessels, sometimes not considered its own category) shock describe one aspect of inadequate delivery of oxygen (DO2) leading to inadequate production of cellular energy. Shock despite proper circulatory function arises from metabolic dysfunction due to inadequate substrate supply or dysfunctional metabolic mechanisms. Oxygen is a very important component in carrying out aerobic metabolism, a vastly more efficient and sustainable method of energy production than anaerobic metabolism which takes place with the absence of oxygen. Lack of oxygen being delivered to tissues from inadequate oxygen content in arterial blood lead to what is known as hypoxemic shock, and may occur from varying reasons.
