Sometimes, a fetal heart rate is abnormal because of something happening in the mothers body. It is common to have a baseline heart rate of between 100-120 bpm in the following situations: Postdate gestation Occiput posterior or transverse presentations Severe prolonged bradycardia (less than 80 bpm for more than 3 minutes) indicates severe hypoxia. The average rate ranges from 110 to 160 beats per minute (bpm), with a variation of 5 to 25 bpm.

The clinical risk status (low, medium, or high) of each fetus is assessed in conjunction with the interpretation of the continuous EFM tracing. What is the baseline of the FHT? Depending on your health status and your babys, nonstress tests (one to two times a week, if not daily) might be a good idea. -absent baseline variability not accompanied by recurrent decels Your JFAC wishes you the best of luck as you start this rewarding journey. 1. Continuous electronic fetal monitoring (EFM), using external or internal transducers, became a part of routine maternity care during the 1970s; by 2002, about 85 percent of live births (3.4 million out of 4 million) were monitored by it.1 Continuous EFM has led to an increase in cesarean delivery and instrumental vaginal births; however, the incidences of neonatal mortality and cerebral palsy have not fallen, and a decrease in neonatal seizures is the only demonstrable benefit.2 The potential benefits and risks of continuous EFM and structured intermittent auscultation should be discussed during prenatal care and labor, and a decision reached by the pregnant woman and her physician, with the understanding that if intrapartum clinical situations warrant, continuous EFM may be recommended.3, There are several considerations when choosing a method of intrapartum fetal monitoring. Periodic changes in FHR, as they relate to uterine contractions, are decelerations that are classified as recurrent if they occur with 50 percent or more of contractions in a 20-minute period, and intermittent if they occur with less than 50 percent of contractions.11 The decrease in FHR is calculated from the onset to the nadir of the deceleration. DR C BRAVADO incorporates maternal and fetal risk factors (DR = determine risk), contractions (C), the fetal monitor strip (BRA = baseline rate, V = variability, A = accelerations, and D = decelerations), and interpretation (O = overall assessment).

Verywell Health's content is for informational and educational purposes only. A concern with continuous EFM is the lack of standardization in the FHR tracing interpretation.5,811 Studies demonstrate poor inter-rater reliability of experts, even in controlled research settings.12,13 A National Institute of Child Health and Human Development (NICHD) research planning workshop was convened in 1997 to standardize definitions for interpretation of EFM tracing.14 These definitions were adopted by the American College of Obstetricians and Gynecologists (ACOG) in 2002,5 and revisions were made in a 2008 workshop sponsored by NICHD, ACOG, and the Society for Maternal-Fetal Medicine.11 The Advanced Life Support in Obstetrics (ALSO) curriculum developed the mnemonic DR C BRAVADO (Table 3) to teach a systematic, structured approach to continuous EFM interpretation that incorporates the NICHD definitions.9,11. During labor, they may give the mother oxygen or change her position to see if that helps the baby or if they need to intervene.

The onset, nadir, and recovery of the deceleration usually coincide with the beginning, peak, and ending of the contraction, respectively.11 Early decelerations are nearly always benign and probably indicate head compression, which is a normal part of labor.15, Variable decelerations (Online Figure I), as the name implies, vary in terms of shape, depth, and timing in relationship to uterine contractions, but they are visually apparent, abrupt decreases in FHR.11 The decrease in FHR is at least 15 bpm and has a duration of at least 15 seconds to less than two minutes.11 Characteristics of variable decelerations include rapid descent and recovery, good baseline variability, and accelerations at the onset and at the end of the contraction (i.e., shoulders).11 When they are associated with uterine contractions, their onset, depth, and duration commonly vary with successive uterine contractions.11 Overall, variable decelerations are usually benign, and their physiologic basis is usually related to cord compression, with subsequent changes in peripheral vascular resistance or oxygenation.15 They occur especially in the second stage of labor, when cord compression is most common.15 Atypical variable decelerations may indicate fetal hypoxemia, with characteristic features that include late onset (in relation to contractions), loss of shoulders, and slow recovery.15. Consider need for expedited delivery (operative vaginal delivery or cesarean delivery). However, FHR with low-quality signals may somehow exaggerate the risk of the fetus suffering from acidemia, thus contributing to an increase in cesarean section rates. The EFM toolkit also offers EFM CE opportunities and C-EFM(R) certification information.

A gradual decrease is defined as at least 30 seconds from the onset of the deceleration to the FHR nadir, whereas an abrupt decrease is defined as less than 30 seconds from the onset of the deceleration to the beginning of the FHR nadir.11, Early decelerations (Online Figure H) are transient, gradual decreases in FHR that are visually apparent and usually symmetric.11 They occur with and mirror the uterine contraction and seldom go below 100 bpm.11 The nadir of the deceleration occurs at the same time as the peak of the contraction.

Continuous electronic fetal monitoring has been shown to reduce the incidence of neonatal seizures, but there has been no beneficial effect in decreasing cerebral palsy or neonatal mortality. The fetus in this tracing also has fetal tachycardia, or an elevated heart rate of 170 -175 beats per minute over a 10 minute period of time. This is a short reference on the physiologic benefits, instrumentation, application and interpretation of fetalheart rate monitoring. Electronic fetal monitoring may help detect changes in normal FHR patterns during labor. Continuous EFM increased cesarean delivery rates overall (NNH = 20) and instrumental vaginal births (NNH = 33).

The Doppler machine is an example of external monitoring and can be used during prenatal visits or labor. Monitoring the fetal heart rate more often can be helpful in high-risk pregnancies. This system can be used in conjunction with the Advanced Life Support in Obstetrics course mnemonic, DR C BRAVADO, to assist in the systematic interpretation of fetal monitoring.

What is the baseline of the FHT? Any type of abnormality spotted in a fetal heart tracing could indicate an inadequate supply of oxygen or other medical issues. Prolonged decelerations (Online Figures K and L) last longer than two minutes, but less than 10 minutes.11 They may be caused by a number of factors, including head compression (rapid fetal descent), cord compression, or uteroplacental insufficiency.
