Abstract
Shock is the result of failure of the circulatory system to adequately deliver oxygen and nutrients to tissues. At the bedside, the clinician synthesizes data from the history, signs of hypoperfusion on physical exam, vital signs and urine output, and laboratory markers of the adequacy of substrate provision to determine the presence of shock. However, prior to the onset of clinically evident shock, the insult is first experienced at a subcellular level by the mitochondria, leading to their description as “canaries in a coal mine” [1]. Ultimately, shock is the result of failure of adequate oxygen delivery (DO2) and utilization within mitochondria, which collectively are responsible for nearly all the oxygen consumption and energy production in the body.
