title: Umbilical artery Doppler flow: an examination of current and best practice.
abstract: A Web-based survey of Royal Australian and New Zealand College of Obstetricians and Gynaecologists (RANZCOG) fellows and trainees who perform or act on umbilical artery Doppler showed heterogeneous reporting practices. Systolic: diastolic ratio is frequently used. Pulsatility index is favoured internationally and by many RANZCOG subspecialists. Unpublished charts are used more often than published. We summarise ideal methods of chart development but recognise that chart choice is guided by professional opinion leaders, day-to-day accessibility and other factors.
