		Shock is caused by any condition that dangerously reduces blood flow, including heart problems (such as heart attack or heart failure), low blood volume (as with heavy bleeding or dehydration), or changes in blood vessels (as with severe allergic reactions or infection).
		Major classes of shock include: cardiogenic shock (associated with heart problems), hypovolemic shock (caused by inadequate blood volume), anaphylactic shock (caused by allergic reaction), septic shock (associated with infections), and neurogenic shock (caused by damage to the nervous system).

	eMedicine - Shock, Distributive : Article Excerpt by: Ruben Peralta, MD, FACS
		Shock is categorized according to etiology, including cardiogenic, hypovolemic, compressive/obstructive shock (eg, cardiac tamponade and pulmonary embolism), distributive shock (eg, severe sepsis, pancreatitis, anaphylaxis), endocrine (eg, adrenal insufficiency, hyper or hypothyroid), neurogenic, and shock due to other miscellaneous causes (eg, carbon monoxide).
		The hemodynamic changes of distributive shock may be subdivided into early or late; these are primarily characterized by the evolution of changes in contractility and dilation of peripheral small vessels and the impact of resuscitation efforts.
		Early septic shock (warm or hyperdynamic) is characterized by peripheral vasodilation that causes flushed warm extremities with a compensatory in.....

	Shock
		Shock is a failure of the circulatory system and is a life-threatening medical emergency.
		Shock can be caused by problems with the heart itself (cardiogenic shock), conditions that block blood flow to or from the heart (extracardiac obstructive shock), severe loss of fluids (hypovolemic shock), or abnormal flow of fluids into the tissues, despite normal or increased heart function (distributive shock).
		Depending on the cause of shock, surgery may be required to repair heart valves or rupture of a ventricle, artificially augment blood flow from the heart, or remove an embolism.

	Shock
		Other features of hypovolaemic shock are similar to those seen in cardiogenic shock and include cool peripheries, decreased urine output and sweating that can also be explained by the sympathetic compensatory response.
		Often in acute cardiogenic shock, the SVR is secondarily elevated (part of the baroreceptor response to shock) to maintain vascular perfusion pressure
		A low aortic diastolic pressure is common in severe shock seen in ICU and may be gently increased with vasopressors (agents that cause vasoconstriction and therefore increase SVR).
