![]() More often, it is done using two flat devices (sensors). Sometimes it's done during labor.Įxternal monitoring can be done by listening to your baby's heartbeat with a special stethoscope. You may have external monitoring at different times during your pregnancy. Two types of monitoring can be done: external and internal. Your baby's heart rate is a good way to tell if your baby is doing well or may have some problems. It also checks the duration of the contractions of your uterus. It keeps track of the heart rate of your baby ( fetus). Sometimes the rate of infusion is stopped, slowed down or increased according to the pattern of contractions.Electronic fetal heart monitoring is done during pregnancy, labor, and delivery. Types of medications used during labor such as Pitocin.Resuscitation, oxygen, fluids, and other lifesaving interventions may be quickly administered once the baby is born. It is hard to help a distressed baby in the uterus: a C-section is the best and fastest way to handle a baby in distress. Emergency cesarean section should be performed within 5 to 30 minutes depending on the circumstances. If fetal heart tones remain non-reassuring despite nursing interventions, the fetus should be delivered by emergency cesarean section. These include the administration of supplemental oxygen, changes in maternal position, increasing intravenous fluids, and the administration of medications that subdue contractions and maximize placental blood flow. Generally, nursing interventions are attempted first to restore normal oxygenation to the baby. If non-reassuring conditions occur, appropriate and timely actions must be taken. Obstetricians and nurses must carefully review fetal monitor strips throughout labor and delivery to ensure fetal heart tones are reassuring and the baby is getting enough oxygen. This may be a sign that the baby is distressed. ![]() Late decelerations begin with a uterine contraction and continue for too long after the contraction has resolved. Variable decelerations are irregular dips in the fetal heart rate that may indicate cord compression, a potentially dangerous condition for the baby. “Variable deceleration” or “late deceleration”, however, may be signs that the baby is not doing well. There is an acceptable range of acceleration and deceleration – or speeding up and slowing down – of fetal heart rates during contractions and labor. A fast heart rate, or tachycardia, may indicate oxygen deprivation. A slow heart rate, or bradycardia, may indicate the baby is not getting enough oxygen delivery to the brain. External monitoring is subject to loss of signal related to maternal positioning, fetal positioning, maternal body fat.Ī normal fetal heart rate range is 115-150 beats per minute (much faster than a normal adult heart rate). The fetal membranes must be ruptured to apply an internal monitor. Internal monitors consist of an electrode attached to the fetal scalp. External monitors (also known as ultrasound transducers) are usually composed of a belt with a doppler ultrasound that is strapped to the pregnant woman’s belly. There are external and internal fetal monitors. Since then, it has become an accepted standard in the management of ob gyn patients who are in labor and close to delivery. FHR was first introduced to the public by Yale in 1958 but did not become widely used in obstetric care until the 1970’s. Killian, suggested that Fetal Heart Rate information could be used to identify the need for intervention for fetal distress. The clinical practice of auscultating fetal heart tones began in 1818 when a Swiss surgeon reported hearing the fetal heart rate by placing his ear against a pregnant woman’s abdomen.
