NCT06655207

Brief Summary

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.

Outcome Measures

Primary Outcomes (2)

  • Assess the performance of Oli as calculated by comparing the output of Oli (up to 1 hour prior to birth) against the clinically documented value of cumulative blood loss ≥ 500ml or any blood loss with signs and/or symptoms of hypovolemia within 24 hour

    6 months

  • To assess the performance of Oli in cumulative blood loss ≥ 1000ml (ACOG)

    14 months

Interventions

Oli is a non-invasive wearable device, designed to provide clinicians with an early indication if the participant is at a higher risk of developing abnormal postpartum uterine bleeding, including postpartum haemorrhage.
