Issues such as hypoxia, however, might slow their heart rate. 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.

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. Umbilical cord influences that can alter blood flow include true knots, hematomas, and the number of umbilical vessels. You scored 6 out of 6 correct.

The NICHD has stated that it is no longer useful to distinguish between short-term and long-term variability and has categorized variability into the following classifications, depending on the amplitude of the FHR tracing: absent (Online Figure C), minimal (Online Figure D), moderate (Online Figure E), and marked (Online Figure F).11, Sleep cycles of 20 to 40 minutes or longer may cause a normal decrease in FHR variability, as can certain medications, including analgesics, anesthetics, barbiturates, and magnesium sulfate.15 Loss of variability, accompanied by late or variable decelerations, increases the possibility of fetal acidosis if uncorrected.15, Sinusoidal pattern is a smooth, undulating sine wave pattern defined by an amplitude of 10 bpm with three to five cycles per minute, lasting at least 20 minutes.11 This uncommon pattern is associated with severe fetal anemia and hydrops, and it usually requires rapid intervention in these settings.15 Similar appearing benign tracings occasionally occur because of fetal thumb sucking or maternal narcotic administration, and generally these will persist for less than 10 minutes.15. Impact of maternal exercise during pregnancy on offspring chronic disease susceptibility.

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. This lets your healthcare provider see how your baby is doing. The workshop introduced a new classification scheme for decision making with regard to tracings.

BJOG: An International Journal of Obstetrics & Gynaecology. Check out a suggested systematic approach from the AAFP below! -can start before, during or after contraction starts 2018;38(5):1327-1331. doi:10.1002/jum.14813. 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. Healthcare providers usually start listening for a baby's heart rate at the 10- to 12-week prenatal visit using a Doppler machine.
