Blood volume increase — percentage?
30-50% increase during pregnancy.
Blood volume increase — percentage?
30-50% increase due to plasma and RBC expansion.
Hemodilution — effect?
Decreases hemoglobin and hematocrit levels.
Hemodilution — effect?
Dilutes blood components, lowers hemoglobin/hematocrit.
Renal GFR — change in pregnancy?
Increases by about 50% to support fetal needs.
Physiological anemia — cause?
Normal dilution, not true anemia.
Blood changes — main purpose?
Supports fetal needs and delivery prep.
Platelet count in pregnancy?
Mild decrease, usually asymptomatic.
Renal adaptation — change?
Increased GFR, decreased serum urea/creatinine.
Blood proteins — change?
Fibrinogen and clotting factors increase.
