Umbilical cord compression is the obstruction of blood flow through the umbilical cord secondary to pressure from an external object or misalignment of the cord itself. Cord compression happens in about one in 10 deliveries.[1]



On cardiotocography (CTG), umbilical cord compression can present with variable decelerations in fetal heart rate.[1]


Umbilical cord compression may be relieved by the mother switching to another position. In persistent severe signs of fetal distress, Cesarean section may be needed.
