An internal monitor is a device that is inserted into the vagina during labor in order to measure the baby’s heart rate. The monitor is attached to a cord that is connected to a machine outside of the body. The machine will then display the baby’s heart rate on a screen. Internal monitors are used in order to help the doctor or midwife to determine how the baby is doing during labor. If the baby’s heart rate is too high or too low, it may be a sign that the baby is in distress and may need to be delivered by cesarean section. Internal monitors are also used to help the doctor or midwife to determine when the baby is ready to be born. When the baby’s heart rate reaches a certain level, it is a sign that the baby is ready to be born.
Internal monitors are generally safe for both the mother and the baby. However, there is a small risk of infection associated with the use of internal monitors. There is also a small risk that the monitor may cause the baby’s heart rate to become erratic. If this happens, the doctor or midwife may decide to deliver the baby by cesarean section. Internal monitors are generally used for high-risk pregnancies or for women who are having twins or triplets.
