AB In  an  overt  cord  prolapse,  a  loop  of  umbilical  cord  is  visualized  either  at  the  introitus  or  on  sterile  speculum  examination  following  membrane  rupture.  Alternatively,  a  small  loop  of  cord  may  be  palpated  at  the  cervical  os.  In  a  “funic”  cord  prolapse,  a  loop  of  umbilical  cord  is  palpated  through  intact  fetal  membranes.  Occult  prolapse  occurs  when  the  umbilical  cord  descends  between  the  presenting  part  and  the  lower  uterine  segment,  but  is  not  visible  or  palpable  on  examination.  Intermittent  compression  of  the  umbilical  cord  with  each  uterine  contraction  may  be  indicated  by  variable  fetal  heart  rate  and  decelerations.  Fetal  hypoxia  may  ensue  if  cord  compression  is  sustained  beyond  the  duration  of  the  contraction,  which  often  happens  with  overt  prolapse.
