Assess maternal vital signs (temperature, blood pressure, pulse), 3. 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. 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).

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. Fetal heart tracing is also useful for eliminating unnecessary treatments. However, the strength of contractions cannot always be accurately assessed from an external transducer and should be determined with an IUPC, if necessary. Late. In 2013, researchers proposed an algorithm for the management of category II fetal heart tracings. A change in baseline FHR is said to occur when the change persists for 10 minutes or longer. early decels present or absent Assessment of heart rate variability (HRV) is a sensitive indicator of autonomic nervous system function and is used in numerous fields of clinical medicine, including cardiology, neurology, and anesthesiology.

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. 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. 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. It means your fetus is neurologically responsive and doesnt have an oxygen deficiency.

A prenatal non-stress test (NST) can be used to assess fetal heart rate and movement at around 26 to 28 weeks of gestation. This fetal heart rate deceleration quiz will help you learn how to differentiate between early decelerations, late decelerations, and variable decelerations. 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. The EFM toolkit also offers EFM CE opportunities and C-EFM. Here's what University of Michigan Medical Students said about the SecondLookTM concept: "The Second Look (files) have been a godsend. The fetal heart rate acts as a screening tool for the healthcare team.
