"Shock" is a term used to describe a situation of cardiovascular collapse. It can arise from several causes and is usually divided into several categories, including: cardiogenic, hemorrhagic, septic, endotoxic, and traumatic shock. These categories are broadly connected by the underlying ultimate failure of the cardiovascular system.
