Osmosis video - Postpartum hemorrhage: Clinical

Postpartum hemorrhage is defined as blood loss of more than 500 mL for a vaginal delivery, or more than 1000 mL for cesarean delivery, within the first 24 hours following childbirth. Signs and symptoms may initially include: an increased heart rate, feeling faint upon standing, and an increased breath rate.

Risk factors for PPH include prolonged labor, a large baby, placenta complications, an infection, or underlying medical conditions. Treatment for PPH depends on the cause and can range from uterine massage to a blood transfusion. Prevention strategies include proper prenatal care, labor monitoring, and active management of the third stage of labor.
