Question 1: Sinusoidal fetal heart rate (cat iii FHR tracing) = repetitive, wave like fluctuations with absent variability and no response to contractions. 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. Hornberger, L. K., & Sahn, D.

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.

What are the rate and duration of the contractions seen on this strip?What intervention would you take after evaluating this strip? 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. if accel is 10 min+, it is a baseline change, 15 bpm above baseline w duration of 15 sec or more but less than 2 min. Currently she serves as President of the Association of Professors of Gynecology and Obstetrics (APGO). American Pregnancy Association. (2007). Most external monitors use a Doppler device with computerized logic to interpret and count the Doppler signals. This web game uses NICHD terminology to identify tracing elements and categorize EFM tracings. Any type of abnormality spotted in a fetal heart tracing could indicate an inadequate supply of oxygen or other medical issues.

Additionally, an Apgar score of less than 7 at five minutes, low cord arterial pH (less than 7.20), and neonatal and maternal hospital stays greater than three days were reduced.22, Tocolytic agents such as terbutaline (formerly Brethine) may be used to transiently stop contractions, with the understanding that administration of these agents improved FHR tracings compared with untreated control groups, but there were no improvements in neonatal outcomes.23 A recent study showed a significant effect of maternal oxygen on increasing fetal oxygen in abnormal FHR patterns.24. Its carbon-14 (614C)\left({ }_{6}^{14} \mathrm{C}\right)(614C) activity is measured to be 60.0% of that in a fresh sample of wood from the same region. Perineal massage: What you need to know before giving it a go. Furthermore, you will need to know what causes these decelerations to happen and if you need to intervene as the nurse.

Variability describes fluctuations in the baseline FHR, whether in terms of frequency, amplitude, or magnitude. 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. Fetal heart tracing is also useful for eliminating unnecessary treatments. The next step is to identify whether there are significant decelerations present. Sarah BSN, RN explains in this video tutorial some clever ways on how to learn these type of fetal heart rate decelerations. Obstet Med. Gradual decrease; nadir Structured intermittent auscultation is a technique that employs the systematic use of a Doppler assessment of fetal heart rate (FHR) during labor at defined timed intervals (Table 1).4 It is equivalent to continuous EFM in screening for fetal compromise in low-risk patients.2,3,5 Safety in using structured intermittent auscultation is based on a nurse-to-patient ratio of 1:1 and an established technique for intermittent auscultation for each institution.4 Continuous EFM should be used when there are abnormalities in structured intermittent auscultation or for high-risk patients (Table 2).4 An admission tracing of electronic FHR in low-risk pregnancy increases intervention without improved neonatal outcomes, and routine admission tracings should not be used to determine monitoring technique.6. However, it can take some practice to hear the heartbeat using this method, especially if the baby is moving around. *reflex late decels*: thought to be in response to vagal stimulation by chemoreceptors in fetal head in response to low oxygen fluid to the laboratory to screen the client for chlamydia b. send a sample of amniotic fluid to the laboratory to test for an elevated Rh-negative titer c. administer immune .

Your JFAC wishes you the best of luck as you start this rewarding journey. The physiology behind late deceleration is uteroplacental insufficiency.16,17 Transient late deceleration patterns may be seen with maternal hypotension or uterine hyperstimulation.

During a term antepartum NST (non-stress test), you notice several variable decelerations that decrease at least 15 bpm and last at least 15 secs long. contraction. Another area of interest is the use of computer analysis for key components of the fetal tracing,29 or decision analysis for the interpretation of the EFM tracing.30 These have not been demonstrated to improve clinical outcomes.29,30 Fetal pulse oximetry was developed to continuously monitor fetal oxygenation during labor by using an internal monitor, requiring rupture of membranes.31 Trials have not demonstrated a reduction in cesarean delivery rates or interventions with the use of fetal pulse oximetry.31.
