Which statement correctly defines postpartum hemorrhage?

Defining postpartum hemorrhage accurately is essential for understanding maternal health and ensuring appropriate care. The statement that defines postpartum hemorrhage as the loss of more than 500 mL of blood after delivery is correct because this quantification is based on established medical standards. Specifically, postpartum hemorrhage is categorized as either primary (occurring within the first 24 hours after delivery) or secondary (occurring after 24 hours but within six weeks postpartum), with the more than 500 mL threshold being a critical measure used within clinical guidelines.

Postpartum hemorrhage can be a significant risk factor for maternal morbidity, and understanding this definition is crucial for healthcare professionals, including doulas, in providing necessary support and identifying complications early.
