AB The  nurse  reports  that  an  infant  may  be  hypotensive  and  is  showing  signs  of  shock.  Hypotension  (diminished  blood  pressure  [BP])  is  distinct  from  shock,  a  clinical  syndrome  of  inadequate  tissue  perfusion  with  the  clinical  signs  noted  in  Section  II.B.  While  hypotension  frequently  accompanies  shock,  there  is  no  consensus  on  the  exact  definition  of  hypotension  in  the  neonate.  Normal  BP  values  for  extremely  premature  infants  are  also  debated.  Data  are  conflicting  for  the  exact  BP  that  requires  treatment  for  every  gestational,  postnatal  age,  and  infant  weight.  Some  define  hypotension  as  a  BP  >2  standard  deviations  below  normal  for  age  or  below  the  fifth  percentile.  For  a  rapid  reference  for  premature  and  term  infants  BP  ranges,  see  Table  65–1  and  for  more  detailed  BP  values,  see  Appendix  C.
