A normal nonstress test will show a baseline fetal heart rate between 110 and 160 beats per minute with moderate variability (5- to 25-interbeat variability) and 2 qualifying accelerations in 20 minutes with no decelerations. "Reactive" is defined as the presence of two or more fetal heart rate accelerations within a 20-minute period. Each ...
A Zigzag pattern of fetal heart rate (FHR) is defined as FHR baseline amplitude changes of more than 25 beats per minute (bpm) with a minimum duration of 2 minutes and maximum of 30 minutes. [19] However, according to another study, even a >1 min duration of the zigzag pattern is associated with an increased risk of adverse neonatal outcomes. [21]
According to a study conducted by Whitcome, et al., lumbar lordosis can increase from an angle of 32 degrees at 0% fetal mass (i.e. non-pregnant women or very early in pregnancy) to 50 degrees at 100% fetal mass (very late in pregnancy). Postpartum, the angle of the lordosis declines and can reach the angle prior to pregnancy.
Labor induction if gestational age >32 weeks; Repeating test same day if <32 weeks, then delivery if BPP <6; 6 Labor induction if >36 weeks if favorable cervix and normal AFI; Repeating test in 24 hours if <36 weeks and cervix unfavorable; then delivery if BPP <6, and follow-up if >6; ≥ 8 Labor induction if presence of oligohydramnios
A 2-MHz probe is recommended for pregnant women who are overweight. The newer EchoHeart 5-MHz transvaginal probes aids in the detection of fetal heart tones (FHT) early in pregnancy (6–8 weeks) and for patients who have a retroverted uterus or throughout pregnancy for FHT detection for women who are obese.
Doppler fetal monitor. In later stages of pregnancy, a simple Doppler fetal monitor can be used to quantify the fetal heart rate. A fetal heartbeat can be detected at around 17 to 20 weeks of gestation when the chambers of the heart have become sufficiently developed. [20]
A contraction stress test (CST) is performed near the end of pregnancy (34 weeks' gestation) to determine how well the fetus will cope with the contractions of childbirth. The aim is to induce contractions and monitor the fetus to check for heart rate abnormalities using a cardiotocograph. A CST is one type of antenatal fetal surveillance ...
The term is also sometimes used to designate late decelerations of fetal heart rate as measured by cardiotocography or an NST, even if there is no other evidence of reduced blood flow to the placenta, normal uterine blood flow rate being 600mL/min.
