EFM certificationFive factors that may potentially decrease uteroplacental perfusion - ANS-Excessive
ucs or hypertonus
maternal hypotension
maternal conditions (CHT, PIH, stress)
placental changes (abruption, degenerative-hypertension, post dates, diabetes)
vasoconstriction
Partial umbilical cord compression may cause occlusion of the low pressure vein,
leading to decreased return of blood to the fetal heart, decreased cardiac output,
hypotension, and a compensatory... - ANS-FHR accel
With complete cord occlusion, the two arteries become occluded, resulting in fetal
hypertension, stimulation of the baroreceptors, and does what to the FHR - ANS-causes
a decel
Which branch of the autonomic nervous system is the most controlling mechanism of
the FHR? - ANS-The parasympathic nervous system
Two functions of the vagus nerve - ANS-1. It is the pathway the parasympathetic
nervous system uses to travel to the heart from the cardioregulatroy center.
2. The transmission of beat to beat irregularity or variability resulting from the irregular
fluctuations in time btwn consecutive fetal cardiac cycles.
Acceleration - ANS-Abrupt in crease in FHR. Abrupt increase is defined as an increase
from onset of accel to peak in <30 sec. Peak must be >15 bpm and must last >15 sec
from onset to return. 15X15 for >32 weeks, 10X10 for under.
Early decel - ANS-Gradual decrease and return of the FHR assoc. w/ a uc. A gradual
decrease is defined as one from the onset to the nadir >30 sec. The nadir occurs at the
same time as the peak of the uc.
Late decel - ANS-gradual decrease (>30 sec from onset to nadir) In most cases, the
onset, nadir, and recovery of the decel occur after the beginning, peak, and ending of
the uc.
Variable decel - ANS-Abrupt (from onset to beginning of nadir in <30 sec) decrease in
FHR. 15X15
