Medical teams track this data using intrauterine pressure catheter placement (IUPC) and continuous electronic fetal monitoring (EFM).[2] IUPC is a straw that is inserted into the womb with a monitor that reads when contractions are coming and how strong they are.[2] EFM's are used to track the fetal heart rate.[2] If either devices indicate that vital signs are off and prolonged labor is beginning, it is important that the medical team begin discussing treatment and alternative options for delivery.
