NCC EFM Cert. Exam
Ductus venosus connects ______ to ______? - ANS-Umb. vein to IVC
Foramen ovale connects _______to______? - ANS-R. atrium to L. atrium
Ductus arteriosus connects _______ to _______? - ANS-Pulm. artery to aorta
Normal rate - ANS-110 to 160 BPM
Average baseline rate at 15wks gestation - ANS-160 BPM
Average rate in fetus with heart block - ANS-60 BPM (intrinsic ventricular or nodal rate)
Sympathetic effects - ANS-Incr. HR, constricted peripheral and visceral blood vessels,
vital organs dilate and receive more blood
Gest. age at which autonomic nervous system is fully developed - ANS-~ 32wks
Primary indicator of fetal oxygenation - ANS-Presence or absence of variability
Location of chemoreceptors - ANS-aortic arch
Chemoreceptors respond to? - ANS-Changes in O2 and CO2
Location of baroreceptors - ANS-Aortic arch and carotid bodies
Maximal reactivity occurs when? - ANS-Late at night
Max duration of fetal nonreactivity? - ANS-80min
Sensitivity - ANS-Probablity of detecting a true positive
Specificity - ANS-Probability that true negative will be detected
False positive - ANS-erroneosly positive when reality is negative
False negative - ANS-erroneously negative when reality is positive
