For many years, assessment of the fetal heart rate was limited to the fetoscope, a direct stethoscope attributed to Adolphe Pinard in 1876. In 1957, Orvan Hess and Ed Hon at Yale University introduced electronic fetal heart rate monitoring as a window into the status of the fetus (Hon and...
By the fifth week of pregnancy, the fetus (usually called an embryo by doctors at this stage) begins to have cardiac activity, though it's coming from a tube-shaped structure rather than a four-chambered heart. The heart continues to develop over the next 4-6 weeks. You often can't he...
FHRP A is a stable heart rate, with a narrow oscillation bandwidth. Isolated accelerations occur that 572 TEN HOF ET AL. Figure 3. Regression lines for each of the 29 fetuses, as calculated by multilevel analysis, for the percentage of body movements (a), the number of body movements per...
Intrapartum assessment of fetal well-being has evolved over the last 40 years, with the primary focus being fetal heart rate assessments. Despite widespread use and initial enthusiasm for the potential for heart rate monitoring to reduce fetal and neonatal mortality and morbidity, conclusive evidence ...

In uncompromised and adequately breathing infants, SpO2 increases from 50–60% in the fetus to 90–95% in the first minutes after birth.4 This increase is needed to match the rise in metabolic rate that comes with the physiological adaptation to extra-uterine life (thermoregulation, breathing ...
Aim of this work was to investigate whether controlled paced maternal respiration has an effect on the occurrence of fetal-maternal heart rate synchronization. In 6 healthy pregnant women (34th - 40th week of gestation) we obtained simultaneous 5 min. fetal and maternal magnetocardiograms (MCG) ...

and maintained with 1–3% isoflurane and 5–6 L/min O2. Ewes were monitored by heart rate, blood pressure, pulse oximetry and end-tidal capnography. Ultrasound was then used to determine litter size, and if multiples were detected, to decide which fetus had the best lie for coil implanta...
