AB During  labor  and  delivery,  fetal  hypoxemia  can  increase  the  risk  of  significant  morbidity  and  mortality.  Causes  of  fetal  hypoxemia  include  any  number  of  insults  to  uterine  blood  flow,  such  as  normal  contractions,  umbilical  cord  compression,  poorly  functioning  placentas,  maternal  hypotension,  and  chronic  maternal  vascular  disease.  Possible  outcomes  include  cerebral  palsy,  neonatal  seizures,  neonatal  hypoxic  ischemic  encephalopathy,  and  intrapartum  fetal  death,  or  stillbirth.  Since  there  are  no  direct  tests  to  diagnose  fetal  hypoxemia,  electronic  fetal  monitoring  (EFM)  serves  as  an  indirect  assessment  of  the  status  of  the  fetus.  Monitoring  of  the  fetal  heart  rate  (FHR)  is  the  primary  modality  used  to  assess  the  well-being  of  the  fetus.  Normal  FHR  measurements  will  accurately  predict  fetal  well-being,  while  abnormal  tracings  suggest  hypoxemia  and  acidemia.  Timely  identification  and  intervention  can  prevent  fetal  death  and  neurologic  injury.
