AB  - The  exact  number  of  cases  of  shock  that  present  to  the  ED  in  the  United  States  is  difficult  to  ascertain  due  to  the  insensitivity  of  clinical  parameters,  current  definitions,  and  lack  of  a  central  database  repository.  Previous  estimates  propose  that  more  than  1  million  cases  of  shock  are  seen  in  the  ED  each  year  in  the  United  States.1  These  estimates  are  largely  based  on  the  assumption  that  hypotension,  defined  as  a  systolic  blood  pressure  <90  mm  Hg,  is  consistent  with  shock  in  adults.  Using  this  definition,  the  incidence  of  patients  with  hypotension  that  present  to  American  EDs  is  approximately  5.6  million  cases  per  year.2
