Abstract

Postpartum hemorrhage (PPH), defined by >500-1000 mL of blood loss following delivery, is the leading and most preventable cause of maternal mortality. Current methods for PPH detection do not provide early indicators of hemorrhage, nor can they quantitatively monitor blood loss in real-time. There is an urgent need for a technology that can monitor occult blood loss, which would otherwise go undetected, in real-time to detect PPH in early stages. A compact, low-cost (
