Pivotal, Prospective, Multi-centre, Single-arm Study to Evaluate the Safety and Effectiveness of Oli for Identification of Patients, During the Intrapartum Period, Who Are at Higher Risk of Developing Abnormal Postpartum Uterine Bleeding, Including Postpartum Haemorrhage

Oli is a predictive, non-invasive device, intended to be placed on the participant's maternal abdomen during the intrapartum period, which can alert healthcare professionals of an impending cumulative blood loss of ≥500 ml (abnormal postpartum uterine bleeding) or cumulative blood loss of ≥1000ml (postpartum haemorrhage) at least 1 hour in advance of birth. This study is being undertaken to assess the performance of Oli measuring cumulative blood loss ≥500ml and ≥1000ml, as well as evaluate its safety profile.
