AB  - Mixed  venous  oxygen  saturation  (Svo2)  can  provide  useful  information  regarding  a  patient’s  clinical  condition.  As  such,  there  continues  to  be  an  interest  in  this  value  as  a  clinical  predictor  of  outcomes.  Svo2  is  measured  at  the  level  of  the  pulmonary  artery.  It  reflects  the  oxygen  saturation  of  the  blood  returning  from  the  body  to  the  heart.  To  obtain  a  true  measurement,  a  blood  sample  is  drawn  from  the  distal  tip  of  a  pulmonary  artery  catheter.  This  allows  the  blood  to  be  a  true  mixture  of  superior  and  inferior  vena  cava  as  well  as  coronary  sinus  blood  (venous  return  from  all  parts  of  the  body).  More  sophisticated  monitoring  exists  whereby  mixed  venous  oxygenation  is  displayed  continuously  via  specialized  pulmonary  artery  catheters.  This  technology  allows  for  early  changes  in  clinical  status  to  be  detected,  though  it  has  not  been  proven  to  be  superior  to  periodic  measurement  via  a  standard  pulmonary  artery  catheter.
