AB Shock  is  circulatory  insufficiency  that  creates  an  imbalance  between  tissue  oxygen  supply  (delivery)  and  oxygen  demand  (consumption).  Such  tissue  hypoperfusion  is  associated  with  decreased  venous  oxygen  content  and  metabolic  acidosis  (lactic  acidosis).  Shock  is  classified  into  four  categories  based  on  etiology:  (a)  hypovolemic,  (b)  cardiogenic,  (c)  distributive  (eg,  neurogenic  and  anaphylactic),  and  (d)  obstructive.
