Postpartum hemorrhage (PPH) is the leading cause of maternal death worldwide (35%), where early detection can significantly reduce mortality risk. State-of-the-art techniques for detecting PPH rely on vital sign monitoring and visually inspecting sanitary pads. However, visual inspection of pads is error-prone and deterioration in vital signs are late indicators of PPH.
