Fetal oxygenation consists of what two basic elements:
o :## Transfer of oxygen from the environment to the fetus (extrinsic factors/external
environment) and Fetal response to interruption of oxygen transfer (intrinsic factors/internal
environment)
Total amount of oxygen in arterial blood consists of two components:
o :## PaO2 and SaO2
% of PaO2, or "floating" oxygen
o :## 1-2%
% of SaO2, or "bound" oxygen

o :## 98-99%
True or False: The "extra" floating oxygen that is dissolved in plasma creates an increased
"pressure" that helps bind oxygen to hemoglobin
o :## True
Oxygen saturation, or SaO2 is...
o :## % of oxygen carried on hemoglobin
Hemoglobin can carry a maximum of ___ molecules of oxygen
What occurs once maternal oxygen reaches the vasculature?
o :## Oxygenated blood travels from the lungs to the uterus via the pulmonary veins, left
atrium and ventricle, aorta, and uterine arteries
What is passive diffusion?
o :## Diffusion of oxygen across the placenta that eventually leads to the spiral arteries that
infiltrate the intervillous space of the placenta. The oxygenated blood bathes the chorionic
villi on the fetal side of the placenta.
True or False: The exchange of oxygen between the maternal and fetal circulations occurs at
the uterine level in the maternal oxygen pathway?

o :## False. This occurs at the placental level.
Oxygen affinity is...
o :## The ability of hemoglobin to acquire and release oxygen molecules. "attraction"
True or False: Higher PaO2 levels in the lungs decrease the hemoglobin's affinity for oxygen
o :## False. It increases the affinity
True or False: Lower PaO2 levels in the body tissues allows oxygen to be readily released
from the hemoglobin
o :## True

Factors that increase oxygen delivery to the tissues include:
o :## Exercise, uterine contractions (labor), increased metabolism, certain medications,
transfusing PRBC
Factors that decrease oxygen delivery to the tissues include:
o :## Hypovolemia, hypoxemia, anemia (mother needs to retain)
