uterine blood supply - uterine arteries deliver oxygenated blood to
spiral arteries which bring oxygen rich blood to
intervillous space of placenta that has fetal
capillaries
- fetal capillaries carry the O2 rich blood to
umbilical VEIN that goes to fetus
-in contrast, the umbilical ARTERIES return waste
products to that intervillous space that go into
mother's venous system
Potential issues that negatively affect Maternal Oxygenation: asthma, hyper- or hypo-
fetal oxygenation ventilation
Maternal Circulation: decreased maternal cardiac
output, hypotension, decreased Hgb
Placental O2 and CO2 Exchange: postterm,
abruption, HTN, hypotension, uterine tachysystole
Fetal circulation: cord compression or occlusion
Fetal hypoxemia - can occur d/t reduced fetal O2 reserves,
excessive uterine activity, or reduced
uteroplacental blood flow
- worsening fetal hypoxemia can lead to abnormal
FHR patterns, mostly minimal or absent variability
from acidemia

(1) hypoxemia vs. (2) hypoxia 1 - reduce O2 in blood
2 - reduced O2 delivery at tissue level
Fetal anaerobic metabolism - occurs when long term O2 delivery is insufficient
to meet cellular needs of tissues
- results in production of lactic acid and other
noncarbonic acids
- ACIDOSIS is the presence of excessive acids in
tissues
acidosis pH below 7.35
pH is low
(acidosis is the process that leads to low blood pH,
or acidemia)
alkalosis pH above 7.45
pH is high
buffers - help maintain acid base homeostasis
- 2 major fetal buffers are plasma bicarbonate and
hgb
