Defining postpartum hemorrhage (PPH) has historically been difficult. Waiting for a patient to meet PPH criteria, particularly in resource-poor settings or in cases of sudden hemorrhage, may delay appropriate intervention. Any bleeding that has the potential to result in hemodynamic instability, if left untreated, should be considered PPH and managed accordingly. PPH can be divided into 2 types: early (< 24 hours after delivery) and late (24 hours to 6 weeks after delivery). Most cases of PPH (>99%) are early.
