Is internal fetal monitoring require an invasive procedure?

Yes: Internal monitoring requires that the bag of water is broken. If it is intact, the doctor will break the bag of water with a tiny plastic hook. If contractions need to be monitored, a small plastic tube (iupc) is slid into the uterus, it gets squeezed during contractions and monitors intensity. If the baby needs to be monitored a small heart rate monitor is attached to the baby's scalp.

Yes.: External fetal monitoring is when we monitor the baby's heart rate with a monitor on your belly. Internal fetal monitoring is when the monitor is placed on the baby's head. This means that the membranes are ruptured and there is not a barrier between the monitor and the baby.
