Questions and Answers
Preferential streaming/Shunting - Answer-fetal circulation pattern that allow more
oxygenated blood to get to the vital organs or fetus during the time of hypoxemia.
Shunts are: ductus venosis, ductus arterioles, foramen ovale
Systemic Vascular Resistance - Answer-constriction of vessels in the periphery of the
body(peripheral vasoconstriction) in an effort to shunt blood to vital organs. occurs in
times of shunting or preferential steaming.
Constrictio of the veins causes an increase in blood pressure. SNS hypertension and
vasoconstriction
Autonomic Nervous system: - Answer-sympathetic and parasympathetic
originate medulla
respiratory control and heart rate
interplay with ANS=variability
Catecholamine Release - Answer-epinephrine and norepinephrine
secreted by adrenal glands
heart rate increase and marked variability
major role in streaming and peripheral vascular constriction
Adrenergic Response - Answer-Think adrenaline
cause heart rate increase and marked variability
adrenergic response or beta adrenergic response also called sympathomimetic
response when the heart rate increases.
Neurologic and neuro genic: - Answer-describe something that is origination in the brain
stem(medulla or CNS)
Variability originates and some decels
Intrauterine resuscitation: - Answer-any intervention used in an effort to correct a fetal
tracing. allow the fetal circulation to correct ro decrease the impact of academia via the
placenta
Aortocaval compression/ venacaval compression - Answer-same thing. major blood
vessel(vena cava and aorta) run up the center of the body. being comprised by the fetus
pregnant women lays are there back.
cardiac return and output decrease
suine hypotension or supine hypotensive syndrome
