Shock

 

Surgical or circulatory shock is the generalized inadequate blood flow which passes through the body. This causes too little flow into the peripheral tissues with its concomitant too little oxygen and too little other nutrients, including tissues the heart itself; in other words- inadequate perfusion. It is difficult to reverse the process of shock once it starts for the above reason, for it progresses into a vicious circle.

Causes

It is mostly caused by low cardiac output which then leads to low blood pressure in the presence of low to medium peripheral resistance.
