While EFM use may be common and widespread, there is controversy about its efficacy, interobserver and intraobserver variability, and management algorithms. Practice Quizzes 1-5 - Electronic Fetal Monitoring Basic and Advanced Study Home About Self Guided Tutorial EFM In-Depth Assessments Fetal Tracing Index References Practice Quizzes 1-5 Try your hand at the following quizzes. Fetal heart rate monitoring during labor. They continue to monitor it during prenatal appointments and during labor. can you recognize these strip elements? Copyright 2009 by the American Academy of Family Physicians. Adequate documentation is necessary, and many institutions are now employing flow sheets (e.g., partograms), clinical pathways, or FHR tracing archival processes (in electronic records). Compared with structured intermittent auscultation, a period of EFM on maternity unit admission results in a lack of improved neonatal outcomes and increased interventions, including epidural analgesia (NNH = 19), continuous EFM (NNH = 7), and fetal blood scalp testing (NNH = 45). Palpate the abdomen to determine the position of the fetus (Leopold maneuvers) 2. Dont hesitate to reach out to us for anything as you progress through your career. 2. Fetal heart rate monitoring measures the heart rate and rhythm of your baby (fetus). -transition: 8-10 cm. repositioning, stopping oxytocin, assessment of hypotension) fails to improve the tracing, deliver rapidly and safely Category II An induction process for inflorescence development, b. What is the baseline of the FHT? UT Southwestern Medical Center. Every 15 to 30 minutes in active phase of first stage of labor; every 5 minutes in second stage of labor with pushing, Assess FHR before: initiation of labor-enhancing procedure; ambulation of patient; administration of medications; or initiation of analgesia or anesthesia, Assess FHR after: admission of patient; artificial or spontaneous rupture of membranes; vaginal examination; abnormal uterine activity; or evaluation of analgesia or anesthesia, 1. Match the term with the following definitions. Dr. Maya Hammoud is Professor and Associate Chair for e-Learning and Enabling Technologies in the Departments of Obstetrics and Gynecology and of Learning Health Sciences at the University of Michigan Medical School. Category I FHR includes all of the following: baseline: 110-160 bpm Faculty, Students, State Boards & Volunteers. In 2013, researchers proposed an algorithm for the management of category II fetal heart tracings. List three primary interventions for fetal tachycardia. -often *correctable by changes in maternal position to relieve pressure* on cord . Your doctor analyzes FHR by examining a fetal heart tracing according to baseline, variability, accelerations, and decelerations. It provides more precise readings that are not affected by the babys movement. It is important to review the pressure tracing before assessing the fetal tracing to accurately interpret decelerations. The different catagories of FHR tracings and their clinical meanings are discussed. These flow changes along with increased catecholamine secretions have what effect on fetal blood pressure and fetal heart rate? A change in baseline FHR is said to occur when the change persists for 10 minutes or longer. V. Fetal heart rate patterns in the second stage of labor. Auscultation of the fetal heart rate (FHR) is performed by external or internal means. Will my heart rate directly affect my babys heart rate during pregnancy? The normal range for baseline FHR is defined by NICHD as 110 to 160 beats per minute (bpm; Online Figure A). It is important to recognize that FHR tracing patterns provide information only on the current acidbase status of the fetus. To provide a systematic approach to interpreting the electronic fetal monitor tracing, the National Institute of Child Health and Human Development convened a workshop in 2008 to revise the accepted definitions for electronic fetal monitor tracing. You are turning on Local Settings. The Fetal Heart Rate Tracing SecondLookTM application is a study aid for learners of the medical professions (specifically Ob/Gyn, nursing and midwifery) to self-test their level of knowledge about this important diagnostic procedure widely used in pre-natal care. You suspect that there could be chronic fetal asphyxia because the score is below. [10] The first step involves identifying whether there are accelerations or moderate variability. or call toll-free from U.S.: (800) 762-2264 or (240) 547-2156 The first set explains the basics of a fetal heart rate tracing. . May 2, 2022 The NCC EFM Tracing Game is part of the free online EFM toolkit at NCC-EFM.org. Compared with EFM alone, the addition of fetal electrocardiography analysis results in a reduction in operative vaginal deliveries (NNT = 50) and fetal scalp sampling (NNT = 33). Tracings of the normal fetal heart rate are between 120 and 160. A meta-analysis showed that if there is absent or minimal variability without spontaneous accelerations, the presence of an acceleration after scalp stimulation or fetal acoustic stimulation indicates that the fetal pH is at least 7.20.19, If the FHR tracing remains abnormal, these tests may need to be performed periodically, and consideration of emergent cesarean or operative vaginal delivery is usually recommended.15 Measurements of cord blood gases are generally recommended after any delivery for abnormal FHR tracing because evidence of metabolic acidosis (cord pH less than 7.00 or base deficit greater than 12 mmol per L) is one of the four essential criteria for determining an acute intrapartum hypoxic event sufficient to cause cerebral palsy.20, When using continuous EFM, tracings should be reviewed by physicians and labor and delivery nurses on a regular basis during labor. Registered Nurse, Free Care Plans, Free NCLEX Review, Nurse Salary, and much more. While caring for a gestational diabetic patient, you encounter a conflict with the attending physician because he refuses to order blood sugars on the patient. Subtle, shallow late decelerations can be difficult to visualize, but can be detected by holding a straight edge along the baseline. It means your fetus is neurologically responsive and doesnt have an oxygen deficiency. In 1822, a French obstetrician gave the first written detailed description of fetal heart sounds. Differentiate maternal pulse from. *moderate baseline variability* The information is reviewed in a stepwise fashion to guide the learner through the evaluation of this commonly-used diagnostic procedure and discusses different clinical scenarios and their impact on patient care. They secure external sensors to the abdomen with an elastic belt or an electrode that resembles a round sticker. What reassuring sign is missing? The Doppler machine is an example of external monitoring and can be used during prenatal visits or labor. Therefore, it is a vital clue in determining the overall fetal condition. --recurrent variable decels Occasional use of Dopplers by a healthcare provider is considered safe. Exerc Sport Sci Rev. Abrupt increases in the FHR are associated with fetal movement or stimulation and are indicative of fetal well-being11 (Online Table B, Online Figure G). Fetal heart tracing is a type of nonstress test that doesnt require any specific preparation. 2023 Dotdash Media, Inc. All rights reserved, Verywell Health uses only high-quality sources, including peer-reviewed studies, to support the facts within our articles. The term hyperstimulation is no longer accepted, and this terminology should be abandoned.11. --> decreased intervillous exchange of oxygen adn CO2 and progressive fetal hypoxia and acidemia, *abrupt, onset <30 sec* visually apparent decreases in FHR below baseline FHR early decels present or absent It can provide lots of information about your babys health during pregnancy. Remember, the baseline is the average heart rate rounded to the nearest five bpm. Healthcare providers usually start listening for a babys heart rate at the 10- or 12-week prenatal visit. Prenatal care in your first trimester. Strongly predictive of normal acid-base status at the time of observation. 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. A normal fetal heart rate is 110 - 160 beats per minute. What Do Braxton Hicks Contractions Feel Like? 2013;6(2):52-57. doi:10.1177/1753495X12473751. duration The clinical risk status (low, medium, or high) of each fetus is assessed in conjunction with the interpretation of the continuous EFM tracing. Furthermore, you will need to know what causes these decelerations to happen and if you need to intervene as the nurse. Cross) Civilization and its Discontents (Sigmund Freud) Forecasting, Time Series, and Regression (Richard T. O'Connell; Anne B. Koehler) Your doctor evaluates the situation by reviewing fetal heart tracing patterns. 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. -pressure on fetal head Must be for a minimum of 2 minutes in any 10-minute segment. Low amplitude contractions are not an early sign of preterm labor. Any written information on the tracing (e.g., emergent situations during labor) should coincide with these automated processes to minimize litigation risk.21, Table 5 lists intrauterine resuscitation interventions for abnormal EFM tracings.9 Management will depend on assessment of the risk of hypoxia and the ability to effect a rapid delivery, when necessary. Sometimes a fetal heart rate is outside the normal range simply because the fetus is moving around. Place the Doppler over the area of maximal intensity of fetal heart tones 3. fundal height 30 cm b. fetal movement count 12 kicks in 12 hours c. fetal heart rate 136/min d. . Incorrect. Correct. 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. The average fetal heart rate is between 110 and 160 beats per minute. MedlinePlus. A baseline of less than 110 bpm is defined as bradycardia.11 Mild bradycardia (100 to 110 bpm) is associated with post-term infants and occipitoposterior position.15 Rates of less than 100 bpm may be seen in fetuses with congenital heart disease or myocardial conduction defects.15 A baseline greater than 160 bpm is defined as tachycardia11 (Online Figure B). Category II : Indeterminate. The fetal heart rate acts as a screening tool for the healthcare team. Variability and accelerations C. Variability and decelerations D. Rate and variability 3. This web game uses NICHD terminology to identify tracing elements and categorize EFM tracings. When using external fetal heart monitoring, the fetal heart rate is generally best found by placing the monitor over the fetal _____. Absent. -prolonged decel *can be due to umbilical cord prolapse*. Intrapartum fetal heart rate monitoring. The main goal is to identify fetuses who are prone to injuries stemming from hypoxia (or a lack of oxygen for fetal tissues). - When considering the effectiveness of Electronic Fetal Monitoring, it comes down to the experience and knowledge of the person identifying the tracings. Question 1: Sinusoidal fetal heart rate (cat iii FHR tracing) = repetitive, wave like fluctuations with absent variability and no response to contractions. Blaize AN, Pearson KJ, Newcomer SC. On the NCLEX exam and in your maternity OB nursing lecture classes, you will have to know how to identify each fetal heart rate tone deceleration. We cant believe weve already reached the 4th and final week of our Countdown to Intern Year series! 140 145 150 155 160 2. Sometimes, you may not be as far along as you thought and its just too early to hear the heartbeat. Continuous EFM increased cesarean delivery rates overall (NNH = 20) and instrumental vaginal births (NNH = 33). -*active labor: 6-8 cm, 3-5 hours* -amnioinfusion can treat it in cases of oligohydramnios or when ROM has occurred to decrease rate of decels and C-sections, Recurrent decel (variable, early, late) defined as, decels occuring w >50% of uterine contractions in any 20 min segment, decrease in FHR >15 bpm measured from most recently determined baseline rate, *lasting >2 min, but <10 min* A tag such as

Detection is most accurate with a direct fetal scalp electrode, although newer external transducers have improved the ability to detect variability. Continuous EFM reduced neonatal seizures (NNT = 661), but not the occurrence of cerebral palsy. Abnormal fetal acidbase status cannot be ruled out. A fetal heart rate gives you and your healthcare team information about your baby's health during pregnancy. External monitoring is performed using a hand-held Doppler ultrasound probe to auscultate and count the.

Once I complete the Second Look, I know I'm ready to quiz. The interpretation of the fetal heart rate tracing should follow a systematic approach with a comprehensive description of the following: *Remember, top strip - FHT; bottom strip - uterine contractions. FHR baseline usually ranges from 120-160 beats per minute (bpm); however, with fetal decelerations, the heart rate usually drops about 40bpm below baseline. Category II tracings may represent an appreciable fraction of those encountered in clinical care. Verywell Health's content is for informational and educational purposes only. The key elements include assessment of baseline heart rate, presence or absence of variability, and interpretation of periodic changes. contraction Electronic fetal monitoring is used to record the heartbeat of the fetus and the contractions of the mother's uterus before and during labor.

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. If the baby is experiencing fetal bradycardia, that means it isn't getting . She lives with her husband and springer spaniel and enjoys camping and tapping into her creativity in her downtime. What happens if my prenatal doctor hears a fetal heart arrhythmia? This is a short reference on the physiologic benefits, instrumentation, application and interpretation of fetalheart rate monitoring. Find and create gamified quizzes, lessons, presentations, and flashcards for students, employees, and everyone else. - 160-200 generally well tolerated w normal variability, Contraction forces are usually reported as, montevideo units *(MVUs)*: represent *total intensity of each contraction over 10 min* period Risk increases with factors such as: A fetal heart rate gives you and your healthcare team information about your babys health during pregnancy. 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. Please try reloading page. presence of at least *2 accels, lasting for 15+ seconds* above baseline and peaking at 15+ bpm in a *20 min window*, >25 bpm variation -can start before, during or after contraction starts FETAL HEART TRACING. The inner tags must be closed before the outer ones. Fetal heart monitoring. Are there accelerations present? What kind of variability and decelerations are noted in this strip? These are called maternal causes and may include: The following methods are used to listen to a fetal heart rate: External monitoring means checking the fetal heart rate through the mothers abdomen (belly). The second set covers acceleration and decelerations. EFM Tracing Game. https://www.acog.org/~/media/For%20Patients/faq015.pdf. Health care professionals play the game to hone and test their EFM knowledge and skills. Early fetal development. Your doctor can confirm the likelihood of hypoxic injury using fetal heart tracing. The NCC EFM Tracing Game uses NICHD terminology. Minimal. Baseline is calculated as a mean of FHR segments that are the most horizontal, and also fluctuate the least. After speaking directly with the physician, the next person in the chain of command you should communicate with is, The best placement for the tocodynamometer to pick up uterine contractions is the, When using a fetal scalp electrode (FSE) you notice an abnormally low FHR on the monitor. Decrease in FHR is 15 bpm or greater, lasting 15 seconds, and < 2 minutes in duration. Internally monitoring involves a thin wire and electrode placed through the cervix and attached to the baby's scalp. The Fetal Heart Rate Tracing SecondLookTM app consists of three slide sets, which cover the basic interpretation of FHR tracings including the determination of baseline and variability, various types of acceleration and decelerations, and some examples and practice cases. Monique Rainford, MD, isboard-certified in obstetrics-gynecology, and currently serves as an Assistant Clinical Professor at Yale Medicine. A way to assess your babys overall health, fetal heart tracing is performed before and during the process of labor. 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. Depending on your health status and your babys, nonstress tests (one to two times a week, if not daily) might be a good idea. From time to time the app may be updated with revised content. Fetal hypoxemia results in biphasic changes in the ST segment of the fetal electrocardiography (FECG) waveform and an increase in the T:QRS ratio.15 The ST-segment automated analysis (STAN) software from Noventa Medical can record the frequency of ST events and, combined with changes in continuous EFM, can be used to determine if intervention during the labor process is indicated.15 Several studies have evaluated FECG analysis, documenting its effectiveness at reducing operative vaginal deliveries, fetal scalp sampling, neonatal encephalopathy, and fetal acidosis (pH < 7.05).2528 One drawback to this technology is that it requires rupture of the membranes and internal fetal scalp monitoring. U.S. Food and Drug Administration. Every piece of content at Flo Health adheres to the highest editorial standards for language, style, and medical accuracy.

I actually went over the Second Look (files) twice - once immediately after doing the lecture and lab to help reinforce what I learned, and then again before the exam as a review. The average fetal heart rate varies depending on the stage of pregnancy. Sarah BSN, RN explains in this video tutorial some clever ways on how to learn these type of fetal heart rate decelerations. You scored 6 out of 6 correct. The Fetal Heart Rate Tracing SecondLookTM mobile application with three complete sets can be downloaded for free from the iTunes and Google Play app stores. Perineal massage: What you need to know before giving it a go. The baby may need to grow for another week or two before you and your healthcare provider can hear it. Espinoza A, Lee W, Belfort M, Shamshirsaz A, Mastrobattista J, Espinoza J. Fetal tachycardia is an independent risk factor for chromosomal anomalies in firsttrimester genetic screening. Continuous electronic fetal monitoring was developed in the 1960s to assist in the diagnosis of fetal hypoxia during labor. The average rate ranges from 110 to 160 beats per minute (bpm), with a variation of 5 to 25 bpm. Normal variations in fetal heart rate occur when the baby is moving or asleep. E Jauniaux, F Prefumo. While it is not always a cause for concern, fetal heart rates outside the normal range may also indicate fetal distress. Maxwell Spadafore is a fourth-year medical student at the University of Michigan Medical School. Differentiate maternal pulse from fetal pulse, 4. Examples of Category II FHR tracings include any of the following: Strongly predictive of normal fetal acidbase status. Absent baseline FHR variability and any of the following: We encourage ALL students to educate themselves about racism in America today and have included a list of-anti-racism resources here: Your Junior Fellow Advisory Council recently chimed in with their advice for surviving and succeeding during intern year. This mobile app covers the following topics: Basics of reading and evaluating fetal heart rate tracings, including baseline determination and variability; the evaluation and biological background of various types of accelerations and decelerations; and a set with case examples for practicing the interpretation of FHR tracings. 3. Fetal heart rate patterns identify which fetuses are experiencing difficulties by measuring their cardiac and central nervous system responses to changes in blood pressure and gases. She is the former chief of obstetrics-gynecology at Yale Health. 1. Ayres-de-Campos D, Spong C, Chandraharan E. FIGO consensus guidelines on intrapartum fetal monitoring: Cardiotocography. Theyll wrap a pair of belts around your belly. -*hypertonus*: abnormally high resting tone >25 mmhg or MVU >400 - 100-110 can be sustained for long periods if normal variability 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. Perform a vaginal examination (check for cord prolapse, rapid descent of the head, or vaginal bleeding suggestive of placental abruption), 6. The next step is to identify whether there are significant decelerations present. . 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. -also *commonly associated w oligohydramnios*, ___ are the most common periodic FHR pattern, *variable decels* 90-150 bpm B. Eunice Kennedy Shriver National Institute of Child Health and Human Development. What are the two most important characteristics of the FHR? A fetal heart rate greater than 160 beats per minute (BPM) is considered fast. Visually apparent, abrupt (onset to peak < 30 seconds) increase in FHR from baseline. Dr. Hammoud has dedicated her career to medical student education and serves in many educational leadership roles locally and nationally. Tapping "Update" will cause the slide decks to be updated. We strive for 100% accuracy, but nursing procedures and state laws are constantly changing. Other times, it indicates a health concern for the baby.
