Vacuum extraction is used in labors where the baby is not progressing down the birth canal as quickly or as well as your doctor or midwife would like. This can be done to prevent a cesarean section. It can be used instead of forceps.
Sometimes this is done if the baby is having trouble as shown by a low or slowed fetal heart rate. This can be a way to speed the birth.
Talk to your doctor or midwife about how they use vacuum extraction and what you can do to prevent it.
