The IUPC is used when labor is progressing slowly or is stalling to ensure that the contractions are strong enough but not too strong. It is typically left in place for the duration of your labor and is attached to your leg to secure it.
Your water must be broken to use the intrauterine pressure catheter. If it has not broken, your doctor or midwife will perform an amniotomy to break it. It is more frequently used with inductions of labor and with the use of pitocin. It may also be used in conjunction with a fetal scalp electrode for internal monitoring of your baby's heart rate.
