title: Delayed postpartum hemorrhage: a rare presentation of carbon monoxide poisoning.
abstract: A 41-year-old woman presented with postpartum hemorrhage and altered mentation. A markedly elevated serum carboxyhemoglobin level was noted. Oxygen therapy was initiated with resolution of the patient's bleeding and improved mental status. Carbon monoxide poisoning is a rare and previously unreported cause of postpartum hemorrhage resulting from a unique pathophysiologic mechanism.
