Quote:
In distributive shock, several different causes result in a loss of peripheral vascular tone with the effect of relative hypovolemia. The hemodynamic profile is usually characterized by a normal or increased cardiac output with a low SVR and low to normal left ventricular filling pressures. The most common form of distributive shock is septic shock. Other forms include anaphylaxis, acute adrenal insufficiency, neurogenic, and liver failure.
