AB Cardiovascular  failure,  or  shock,  can  be  caused  by  (1)  depletion  of  the  vascular  volume;  (2)  compression  of  the  heart  or  great  veins;  (3)  intrinsic  failure  of  the  heart  itself  or  failure  arising  from  excessive  hindrance  to  ventricular  ejection;  (4)  loss  of  autonomic  control  of  the  vasculature;  (5)  severe  untreated  systemic  inflammation;  and  (6)  severe  but  partially  compensated  systemic  inflammation.  If  the  shock  is  decompensated,  the  mean  blood  pressure  or  the  cardiac  output  (more  precisely,  the  product  of  the  pressure  and  output)  will  be  inadequate  for  peripheral  perfusion.  In  compensated  shock,  the  perfusion  will  be  adequate  but  only  at  the  expense  of  excessive  demands  on  the  heart.  Depending  on  the  type  and  severity  of  cardiovascular  failure  and  on  response  to  treatment,  shock  can  go  on  to  compromise  other  organ  systems.  This  chapter  discusses  the  cardiovascular  and  pulmonary  disorders  associated  with  shock.
