fetal heart tracing quiz 12

Fetal heart rate monitoring during labor. They continue to monitor it during prenatal appointments and during labor. This depends on the source and duration of your increased heart rate. These settings will apply for this game only and take precedence over Global Settings that are set on the Customize page. The average rate ranges from 110 to 160 beats per minute (bpm), with a variation of 5 to 25 bpm. They secure external sensors to the abdomen with an elastic belt or an electrode that resembles a round sticker. FETAL HEART TRACING. It is important to review the pressure tracing before assessing the fetal tracing to accurately interpret decelerations. Your healthcare provider may do fetal heart monitoring during late pregnancy and labor. Fetal heart tracing allows your doctor to measure the rate and rhythm of your little one's heartbeat. Buttocks. Decelerations (D). Sometimes, you may not be as far along as you thought and its just too early to hear the heartbeat. 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. Obstet Gynecol 1987; 70:191. 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). 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. Issues such as hypoxia, however, might slow their heart rate. --> 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 Fetal heart rate (FHR) may change as they respond to different conditions in your uterus. 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? and more. It can vary by 5 to 25 beats per minute. 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: Fetal Tracing Quiz 1. Umbilical cord influences that can alter blood flow include true knots, hematomas, and the number of umbilical vessels. This is most likely to be done in the late stages of your pregnancy and it might be combined with other tests to see if you have either diabetes or high blood pressure both of which can cause problems. 2015;43(4):198-203. doi:10.1249/JES.0000000000000058. What Do Braxton Hicks Contractions Feel Like? Abdomen. 140 Correct . What are the two most important characteristics of the FHR? 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. The Doppler machine is an example of external monitoring and can be used during prenatal visits or labor. 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. This website provides entertainment value only, not medical advice or nursing protocols. 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). ____ Late A.) -absent baseline variability not accompanied by recurrent decels At 12 h after incubation, the cells on the . In addition, you must know what is causing each type of deceleration, such as uteroplacental insufficiency or umbilical cord compression. 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 Are there accelerations present? Healthcare providers usually start listening for a babys heart rate at the 10- to 12-week prenatal visit using a Doppler machine. Three causes for these decelerations would be. Initiate oxygen at 6 to 10 L per minute, 5. 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.

No. 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). Whenever possible, they will implement measures to prevent an unfavorable outcome. Calculated as amplitude of peak-to-trough in bpm.

Second-stage fetal heart rate abnormalities and type of neonatal acidemia. 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. Palpate for uterine contraction during period of FHR auscultation to determine relationship, 5. The recommendations for the overall management of FHR tracings by NICHD, the International Federation of Gynecology and Obstetrics, and ACOG agree that interpretation is reproducible at the extreme ends of the fetal monitor strip spectrum.10 For example, the presence of a normal baseline rate with FHR accelerations or moderate variability predicts the absence of fetal acidemia.10,11 Bradycardia, absence of variability and accelerations, and presence of recurrent late or variable decelerations may predict current or impending fetal asphyxia.10,11 However, more than 50 percent of fetal strips fall between these two extremes, in which overall recommendations cannot be made reliably.10 In the 2008 revision of the NICHD tracing definitions, a three-category system was adopted: normal (category I), indeterminate (category II), and abnormal (category III).11 Category III tracings need intervention to resolve the abnormal tracing or to move toward expeditious delivery.11 In the ALSO course, using the DR C BRAVADO approach, the FHR tracing may be classified using the stoplight algorithm (Figure 19), which corresponds to the NICHD categories.9,11 Interventions are determined by placing the FHR tracing in the context of the specific clinical situation and corresponding NICHD category, fetal reserve, and imminence of delivery (Table 4).9,11, If the FHR tracing is normal, structured intermittent auscultation or continuous EFM techniques can be employed in a low-risk patient, although reconsideration may be necessary as labor progresses.2 If the FHR tracing is abnormal, interventions such as position changes, maternal oxygenation, and intravenous fluid administration may be used. Mild to moderate heart rate changes in otherwise healthy women generally do not negatively affect the babys heart rate. The first set explains the basics of a fetal heart rate tracing. The EFM toolkit also offers EFM CE opportunities and C-EFM. See permissionsforcopyrightquestions and/or permission requests. ____ Early B.) Intrapartum fetal monitoring was developed in the 1960s to identify events that might result in hypoxic ischemic encephalopathy, cerebral palsy, or fetal death. -pressure on fetal head -recurrent late decel w moderate baseline variability Fluctuations in the baseline FHR that are irregular in amplitude and frequency. 140 145 150 155 160 2. 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. 2023 National Certification Corporation. -*hypertonus*: abnormally high resting tone >25 mmhg or MVU >400 Click on the link below to ask for help or provide us feedback about this product.

However, extensive use at home could lead to unanticipated negative consequences. > 15 secs long, but < 2 min long 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. The NCC EFM Tracing Game uses NICHD terminology. 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. Maxwell Spadafore is a fourth-year medical student at the University of Michigan Medical School. NCC EFM Tracing Game. Variability describes fluctuations in the baseline FHR, whether in terms of frequency, amplitude, or magnitude. This lets your healthcare provider see how your baby is doing. Talk with your healthcare provider if you're concerned about your babys heart rate or if your pregnancy is high-risk. Remember, the baseline is the average heart rate rounded to the nearest five bpm.

Dont hesitate to reach out to us for anything as you progress through your career. ACOG recommends using a three-tiered system for the categorization of FHR patterns. 1. When you've finished these first five, here are five more. 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. A more recent article on intrapartum fetal monitoring is available. University of Rochester Medical Center. Well be concluding our series with a review of Fetal Heart Tracings. -*occur in presence of normal FHR variability* Question 1: Sinusoidal fetal heart rate (cat iii FHR tracing) = repetitive, wave like fluctuations with absent variability and no response to contractions.

Needs immediate intervention; may be due to severe fetal anemia, abdominal trauma or serious fetal infection. The perception that structured intermittent auscultation increases medicolegal risk, the lack of hospital staff trained in structured intermittent auscultation, and the economic benefit of continuous EFM from decreased use of nursing staff may promote the use of continuous EFM.8 Online Table A lists considerations in developing an institutional strategy for fetal surveillance. Yes, and the strip is reactive. By Brandi Jones, MSN-ED RN-BC selected each time a collection is played. -tachycardia, -minimal baseline variability Baseline is calculated as a mean of FHR segments that are the most horizontal, and also fluctuate the least. She is the former chief of obstetrics-gynecology at Yale Health. Sometimes, a fetal heart rate is abnormal because of something happening in the mothers body. The second half of the Must be for a minimum of 2 minutes in any 10-minute segment. A stethoscope or fetoscope can be used by anyone after 20 or 22 weeks of pregnancy.
