Location of baroreceptors - Aortic arch and carotid bodies Maximal reactivity occurs when? - Late at night Max duration of fetal nonreactivity? - 80min Sensitivity - Probablity of detecting a true positive Specificity - Probability that true negative will be detected False positive - erroneosly positive when reality is negative False negative - erroneously negative when reality is positive NST - Two 15x15 accels in 20min (up to 40min) % of false positive CSTs? - ~ 30% BPP components - 1) Fetal breathing movements

  1. Gross body movements
  2. Fetal tone
  3. Reactive fetal heart rate
  4. Qualitiative amniotic fluid volume

Signif. neonatal morbidity occured when ____min or longer elapsed between onset of HFR decel and delivery. - 18min Normal arterial pH for healthy vaginal deliveries? - 7.28+/- 0. Normal arterial pO2 for healthy vaginal deliveries? - 18.0 +/- 6. Normal arterial pCO2 for healthy vaginal deliveries? - 49.2 +/- 8. Normal base deficit for healthy vaginal deliveries? - Less than 12 pH at which acidosis - 7.2 (7.1) Tachysystole - >5 contractions in 10min Baseline (defn) - mean FHR rounded to increments of 5 BPM during a 10min perioud excl. periodic or episodic changes, contractions, periods of marked variability, and segments of baseline that differ by >25 BPM Sinusoidal pattern? - Fetal anemia As many as ___% of infants with complete heart block have assoc. congenital cardiac malformations. - 50% Mortality rate for newborns with complete heart block - 25%

Newborn with complete heart block in absence of congen. heart disease frequently has neonatal ___________. - Lupus erthematosus Baseline variability (defn) - Fluctuations in baseline FHR >2 cycles per minute (peak to trough); irregular in amplitude and frequency Minimal baseline variability - > undetectable but <or= 5bpm Moderate baseline variability - 6 - 25 bpm Marked variability - >25 bpm T/F Performing fetal stimulation is appropriate during decels or bradycardia. - FALSE - Fetal stim should be performed when FHR is at the baseline. Early Decel (defn) - visually apparrent GRADUAL decrease (onset to nadir >=30sec of FHR below baseline), nadir occurs at peak of contraction Early decel (physiology) - Fetal head copmression (vagal reflex), often sen between 4-6cm dilation
