Shock is one of the most important problems with which physicians will contend with.  The magnitude of the problem is illustrated by the high mortality associated with shock.  Assessment of perfusion is independent of arterial pressure, in that hypotension does not always need to be present to define shock.  Emphasis in defining shock is based on tissue perfusion in relation to cellular function.
