INTRAPARTUM 2; fetal responses Flashcards
neurologic system
increased ______________pressure
The fetal heart rate (FHR) decreases by as
much as _____ bpm during a contraction, as soon
as contraction strength reaches _____mmHg
intracranial
5 pbm, 40 mmHG
Cardiovascular System
During a contraction, the arteries of the uterus are sharply
______________
The amount of nutrients, including oxygen, exchanged
during this time is _____________ = slight but ____________
fetal hypoxia.
Increased intracranial pressure caused by uterine pressure
on the fetal head serves to keep circulation from falling
below normal during the duration of a ______________.
Early fetal deceleration can occur with intracranial
pressures of 40 to 55 mm Hg, as the head pushes against
the cervix.
