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 ...
Baseline FHR variability is determined in a 10-minute window, excluding accelerations and decelerations. Baseline FHR variability is defined as fluctuations in the baseline FHR that are irregular in amplitude and frequency. The fluctuations are visually quantitated as the amplitude of the peak-to-trough in beats per minute.
The use of fetal scalp blood testing originated in Germany in 1961 and required 0.25 mL of blood drawn from the fetus. [1] As one of the first methods of monitoring fetal wellbeing during labor, there were many disadvantages including the need for at least 3 cm dilation of the mother and extreme precision from the physician performing the procedure.

Cardiotocography is used to monitor fetal heart rate. Decreased movement felt by the mother; Meconium in the amniotic fluid ("meconium stained fluid") Non-reassuring patterns seen on cardiotocography: increased or decreased fetal heart rate (tachycardia and bradycardia), especially during and after a contraction; decreased variability in the ...
Calculating your fat-burning heart rate isn't rocket science, but it requires some math. The first step is determining your maximum heart rate (MHR), which you can estimate by subtracting your age ...
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 ...
"In essence, this money has been stolen from all of us for all these years," said an 84-year-old woman whose late husband's Social Security benefits were slashed. "It's not fair."
