SHOCK
Shock is an abnormal physiologic state caused by inadequate oxygenation of vital organs.
Adequate oxygen delivery fundamentally requires the following:
An effectively pumping heart
Table 3-1
Causes of Shock
Hemorrhagic Shock:
inadequate circulating blood volume due to acute
blood loss
Neurogenic Shock:
inadequate circulating blood volume due to spinal cord
paralysis
Cardiogenic Shock:
ineffective heart pumping due to mechanical reasons
Septic Shock:
due to overwhelming infection
Anaphylactic Shock:
due to an overwhelming allergic reaction
Sufficient circulating blood volume to transport oxygen
Although shock may be produced by a number of mechanisms, the causes likely to be
encountered in the wilderness are summarized in
Table 3-1
