The interpretation of the fetal heart rate tracing should follow a systematic approach with a full qualitative and quantitative description. The second set covers acceleration and decelerations. Rate and decelerations B. ACOG recommends using a three-tiered system for the categorization of FHR patterns. Quiz, Chapter 24: Adolescent Sexual Activity and Teenage Pregnancy. 2 ): a convolutional neural network (CNN) that captures the salient characteristics from ultrasound input images; a convolution gated recurrent unit (C-GRU) [ 16] that exploits the temporal coherence through the sequence; and a regularized loss function, called The average rate ranges from 110 to 160 beats per minute (bpm), with a variation of 5 to 25 bpm. (2007). Gradual decrease; nadir . Perform a vaginal examination (check for cord prolapse, rapid descent of the head, or vaginal bleeding suggestive of placental abruption), 6. ", "The Second Look files are phenomenal and were an excellent way to test my knowledge after I had studied a bit.". An increase in risk status during labor, such as the diagnosis of chorioamnionitis, may necessitate a change in monitoring from structured intermittent auscultation to continuous EFM. Study with Quizlet and memorize flashcards containing terms like What is the most common OB procedure done?, What is the goal fo fetal monitoring?, What is the downside to fetal heart monitoring? Continuous EFM may adversely affect the labor process and maternal satisfaction by decreasing maternal mobility, physical contact with her partner, and time with the labor nurse compared with structured intermittent auscultation.7 However, continuous EFM is used routinely in North American hospitals, despite a lack of evidence of benefit. accelerations: present or absent, -bradycardia not accompanied by absent baseline variability 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. Prior . Fetal bradycardia is a fetal heart rate of less than that 110 bpm, which is sustained for greater than or equal to 10 minutes. If any problems arise, reviews are done more frequently. Contractions are classified as normal (no more than five contractions in a 10-minute period) or tachysystole (more than five contractions in a 10-minute period, averaged over a 30-minute window).11 Tachysystole is qualified by the presence or absence of decelerations, and it applies to spontaneous and stimulated labor. What is the primary goal of effective communication in the care of the intrapartum patient? What are the two most important characteristics of the FHR? contraction A person viewing it online may make one printout of the material and may use that printout only for his or her personal, non-commercial reference. Questions and Answers 1. What kind of variability and decelerations are noted in this strip? Fetal heart rate (FHR) may change as they respond to different conditions in your uterus.

Fetal Tracing Quiz 1. . Heart (British Cardiac Society),93(10), 12941300. If the heart rate is out of the normal range, the team can do an ultrasound or order blood work. Here's generally what to expect: Weeks 10 to 12 of pregnancy are very exciting for expectant parents. For example, if it is difficult to find the heartbeat using a Doppler before 16 weeks. Our proposed deep learning solution consists of three main components (see Fig. Copyright 2009 by the American Academy of Family Physicians. Scroll down for another when you're done. Category I FHR includes all of the following: baseline: 110-160 bpm External monitoring is performed using a hand-held Doppler ultrasound probe to auscultate and count the. The fetal heart tracing indicates multiple variable decelerations. Visually apparent, abrupt (onset to peak < 30 seconds) increase in FHR from baseline. 4. 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. -*active labor: 6-8 cm, 3-5 hours* Fetal heart rate monitoring may be performed exter-nally or internally. Professionals using Electronic Fetal Monitoring in their practice should also take advantage of: The EFM Resources page with linked papers and articles including the NCC monograph Fetal Assessment and Safe Labor Management authored by Kathleen Rice Simpson, PhD, RNC-OB, CNS-BC, FAAN. Amnioinfusion for umbilical cord compression in the presence of decelerations reduced: fetal heart rate decelerations (NNT = 3); cesarean delivery overall (NNT = 8); Apgar score < 7 at five minutes (NNT = 33); low cord arterial pH (< 7.20; NNT = 8); neonatal hospital stay > three days (NNT = 5); and maternal hospital stay > three days (NNT = 7). They do a great job of both teaching and quizzing you on the relevant material. 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. 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). The Fetal Heart Rate Tracing SecondLookTM app will display a prompt if new updates are available for download. Be sure to ask any questions you might have beforehand. *NO late or variable decels* Yes, and the strip is reactive. Fetal heart rate (FHR) monitoring is the most widely used tool in clinics to assess fetal health. 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.

Relevant ACOG Resources, American College of Obstetricians and Gynecologists Issues such as hypoxia, however, might slow their heart rate. External monitoring (unless noted differently), paper speed is 3cm/min. https://www.mayoclinic.org/tests-procedures/nonstress-test/about/pac-20384577 American Pregnancy Association. 1. Brunner and Suddarth's Textbook of Medical-Surgical Nursing (Janice L. Hinkle; Kerry H. Cheever) Business Law: Text and Cases (Kenneth W. Clarkson; Roger LeRoy Miller; Frank B. ____ Early B.) You have to lie down or sit in a reclined position for the test, which lasts about 20 minutes. Therefore, it is a vital clue in determining the overall fetal condition. Acceleration Together with Flo, learn how fetal heart tracing actually works. We strive for 100% accuracy, but nursing procedures and state laws are constantly changing. Onset, nadir, and recovery of the deceleration occur after the beginning, peak, and ending of the contraction, respectively. Basic 5 areas to cover in FHR description: 1) baseline rate 2) baseline FHR variability: absent, minimal (<5), moderate/normal (6-25bpm), marked >25bpm 3) presence of accelerations 4) periodic or episodic decels 5) changed or trends in FHR patterns over time Common causes of FHR >160? 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. Your doctor analyzes FHR by examining a fetal heart tracing according to baseline, variability, accelerations, and decelerations. Currently she serves as President of the Association of Professors of Gynecology and Obstetrics (APGO). 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. Differentiate maternal pulse from fetal pulse, 4. Braxton Hicks vs. Real Contractions: How to Tell the Difference? Theyll wrap a pair of belts around your belly. They really aren't intended for home monitoring. You are turning on Local Settings. You must know how to identify early decelerations, late decelerations, and variable decelerations. to access the EFM tracing game and to take full advantage of all the resources available. -can start before, during or after contraction starts < 32 weeks EGA: peak 10 bpm above baseline, duration 10 seconds but < 2 minutes from onset of the acceleration to return to baseline. *MVUs >200 adequate* for 90% of labors to progress, -*tachysystole: 5+ contractions in 10 minutes* without evidence of fetal distress early decels present or absent Fetal pulse oximetry has not shown a reduction in cesarean delivery rates. What is the baseline of the FHT? Ordinarily, your babys heart beats at a faster rate in the late stage of pregnancy, when theyre especially active. Your doctor can confirm the likelihood of hypoxic injury using fetal heart tracing. However, you don't need to worry about this right now especially if you prepare well with the help of our amazing quiz! Registered Nurse, Free Care Plans, Free NCLEX Review, Nurse Salary, and much more. *second stage: pushing and birth* . Assessments - Electronic Fetal Monitoring Assessments Ready to test yourself? Continuous EFM reduced neonatal seizures (NNT = 661), but not the occurrence of cerebral palsy. What interventions would you take after evaluating this strip and why? In 2013, researchers proposed an algorithm for the management of category II fetal heart tracings. Every piece of content at Flo Health adheres to the highest editorial standards for language, style, and medical accuracy. A stethoscope or fetoscope can be used by anyone after 20 or 22 weeks of pregnancy. The use of amnioinfusion for recurrent deep variable decelerations demonstrated reductions in decelerations and cesarean delivery overall. BASIC Fetal Heart Monitoring This workshop was developed for the RN with 0-6 months experience in L&D. The course will define methods of monitoring, instrumentation, physiology and pathophysiology of the FHR, FHR characteristics, as well as review common antenatal testing methods. BJOG: An International Journal of Obstetrics & Gynaecology. Healthcare providers monitor fetal heart rate during labor to watch how the baby responds to contractions, medications, tests, and pushing. Dont hesitate to reach out to us for anything as you progress through your career. That being said, its still critical for you to know how to interpret a strip. causes: fetal stimulation, mild/transient hypoxemia, drugs, *10 bpm or more above baseline* with duration of *10 sec or more, but less than 2 min* Have you tested your EFM skills lately? For simplicity, assume that the tags are separated by spaces, and 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. A change in baseline FHR is said to occur when the change persists for 10 minutes or longer. Discontinue oxytocin (Pitocin) infusion, if in use, 4. . Your doctor conducts intrapartum monitoring of fetal heart rate to pinpoint unusual patterns resulting from an inadequate supply of oxygen. Maternity Nursing Lecture Fetal Heart Rate Decelerations: This video explains fetal heart rate tone decelerations (early decelerations, late decelerations , . None. Find the toco, or uterine contraction tracing, in the bottom half of the strip. Coussons-Read ME. Get started for free! The baseline when the woman's abdomen is relaxed will be from zero to 10. We cant believe weve already reached the 4th and final week of our Countdown to Intern Year series! Accelerations last from 15 seconds to 10 minutes, and the majority occur in conjunction with fetal movements. 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. International Journal of Gynecology & Obstetrics. In case of ECM tracing w decreased or absent variability (high false + rates), you can do what ancillary tests? Yes. It provides more precise readings that are not affected by the babys movement. https://www.ncbi.nlm.nih.gov/pubmed/19546798 Your doctor evaluates the situation by reviewing fetal heart tracing patterns. 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. These segments help establish an estimated baseline (for a duration of 10 minutes) which is expressed in beats per minute. *bpm = beats per minute. This content is owned by the AAFP. Continuous EFM increased cesarean delivery rates overall (NNH = 20) and instrumental vaginal births (NNH = 33). Am J Obstet Gynecol 1981; 140:435. -absent baseline variability not accompanied by recurrent decels For more information on the use, interpretation and management of patients based on Fetal Heart Tracings check out the resources below. Place the Doppler over the area of maximal intensity of fetal heart tones, 3. E Jauniaux, F Prefumo. The inner tags must be closed before the outer ones. This fetal heart rate deceleration quiz will help you learn how to differentiate between early decelerations, late decelerations, and variable decelerations. . https://www.uptodate.com/contents/nonstress-test-and-contraction-stress-test?search=fetal%20heart%20rate%20assessment&source=search_result&selectedTitle=3~138&usage_type=default&display_rank=3 What kind of variability and decelerations are seen in this strip?What interventions, if any, would you take after evaluating this strip? Subtle, shallow late decelerations can be difficult to visualize, but can be detected by holding a straight edge along the baseline. For example, if there is a drop in FHR, and then 30 seconds later it rises again, this is more likely a deceleration than a fetal bradycardia. Category II : Indeterminate. A tag such as

Match the term with the following definitions. Second-stage fetal heart rate abnormalities and type of neonatal acidemia. It is important to review the pressure tracing before assessing the fetal tracing to accurately interpret decelerations. 2013;6(2):52-57. doi:10.1177/1753495X12473751. Tracings meeting these criteria are predictive of normal fetal acid-base balance at the time of observation. Are there accelerations present? List three primary interventions for fetal tachycardia. Powered by Powered by FETAL HEART TRACING. ____ Late A.) -transition: 8-10 cm. Needs immediate intervention; may be due to severe fetal anemia, abdominal trauma or serious fetal infection. -nadir of decel occurs at the same time as the peak of uterine contraction and is a *mirror image of contraction* The FHR normally exhibits variability, with an average change of 6 to 25 bpm of the baseline rate, and is linked to the fetal central nervous system. Decrease in FHR is 15 bpm or greater, lasting 15 seconds, and < 2 minutes in duration. Practice basic fetal tracing analysis with some quizzes: Quizzes 1-5 Quizzes 6-10 Combine your ability to read fetal tracings with clinical management with some cases: Cases 1-5 If you want to see how you are doing overall, try the comprehensive assessment: See permissionsforcopyrightquestions and/or permission requests. Intrapartum fetal monitoring was developed in the 1960s to identify events that might result in hypoxic ischemic encephalopathy, cerebral palsy, or fetal death. 2018;38(5):1327-1331. doi:10.1002/jum.14813. *umbilical cord compression*, which can result from cord wrapping, fetal anomalies, or knots in cord Typically performed in the later stages of pregnancy and during labor, fetal heart tracing results can say a lot about the health of your baby. A wooden artifact is found in an ancient tomb. This mobile application is designed for learners of the biomedical sciences, especially students and practitioners in the fields of obstetrics, gynecology, nursing, and midwifery. It can vary by 5 to 25 beats per minute. In addition, she explains how to identify each decelerations which makes learning this material very easy to remember. Palpate the abdomen to determine the position of the fetus (Leopold maneuvers), 2. 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. Healthcare providers usually start listening for a baby's heart rate at the 10- to 12-week prenatal visit using a Doppler machine. a. Join the nursing revolution. Matching 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. Electronic fetal monitoring may help detect changes in normal FHR patterns during labor. Category I FHR tracings include all of the following: Category II FHR tracings include all FHR tracings not categorized as Category I or Category III. The Value of EFM Certification (One Team One Language), showcases the national PSA campaign Your Baby Communicates along with peer-to-peer video discussions on the value of EFM Board Certification.
