Shock - "Circulatory collapse characterized by a progressively diminishing circulating blood volume relative to the capacity of the vascular system, leading to acute failure of perfusion of vital organs.

Shock may be caused by a change in one of three basic locations in the cardiovascular system:

  • cardiac shock caused by damage to the pump
  • hypovolaemic shock due to decreased blood volume
  • vasculogenic shock, in which the blood volume is normal but blood is pooled in in dilated peripheral blood vessels and may be caused by endotoxins or neural stimulation (trauma)" (B101)
