What kind of hemoglobin is found in a fetus? About how much of it is present
at birth? Answer - Hgb F. At birth, Hgb F is primary hemoglobin (60-80%).
What is special about Hgb F? Answer - high oxygen affinity, meaning that it
holds onto the oxygen better than HgbA. Which enhances transfer of oxygen
from maternal circulation to fetal RBC throughout pregnancy.
What is Hgb levels in a Preterm Newborn, Normal Newborn? Answer - Pre-
Term Newborn: ~12-14 g/dL
Normal Newborn: ~16-18 g/dL
When does a newborns Hgb begin to trend and where abouts does it land?
Answer - At 4-8 weeks it goes to ~9-11gL
Why does Hbg fall after birth? Answer - Hgb F has a higher affinity than Hgb A,
for O2. Once the baby is born there is plenty of O2 available to the baby, it is
not competing to drawn O2 from the maternal system, so it doesn't need a
high affinity Hgb.
The Hgb A releases the O2 easier to the tissues.
