Umbilical cord compression occurs when the umbilical cord, which connects a fetus to the placenta, is squeezed or pinched. This can restrict blood flow and oxygen to the fetus, potentially leading to complications during pregnancy or labor. It often happens during contractions or if the fetus is in an unusual position. Symptoms of umbilical cord compression may include changes in the fetal heart rate, which can be monitored during labor. Healthcare providers may take steps to relieve the compression, such as changing the mother's position or, in some cases, performing a cesarean section to ensure the safety of both the mother and the baby.
