This series on maternity care will highlight a range of maternity emergencies and detail the pathophysiology as well as their prehospital treatment and management. The series starts with antepartum haemorrhage and will progress through the pregnancy journey to the postpartum in each episode. Antepartum haemorrhage is serious and unpredictable, and the paramedic plays an important role in identifying its symptoms and managing it. The term woman and mother is used, but pronouns may need to be adapted because of patient preference.
