The average blood loss for a vaginal birth of a single fetus ranges from 300 to 500 mL (10% of blood volume).The typical blood loss for women who gave birth by cesarean is 500 to 1000 mL (15% to 30% of blood volume).During the first few days after birth the plasma volume decreases further as a result diuresis.Pregnancy-induced hypervolemia (an increase in blood volume of at least 35%)allows most women to tolerate considerable blood loss during childbirth.
