Participants and methods BP was measured sequentially in 72 women of any gestation requiring the use of a large-size (N=36, arm circumference ≥33 cm) or medium-size cuff (N=36, arm circumference <33 cm) alternating between a mercury sphygmomanometer and the Omron HBP-1300 device. Results The Omron HBP-1300 is accurate in pregnancy with a mean device–observer difference of 3±6 and 1±6 mmHg for systolic BP and 2±5 and 3±6 mmHg for diastolic BP in women requiring the use of the medium and large cuff, respectively. Conclusion The Omron HBP-1300-automated BP device can be recommended for use in pregnant women with medium-arm or large-arm circumferences. aAntenatal Hypertension Clinic bFetal Medicine Research Institute, King’s College Hospital, London, UK Correspondence to Nikos A.
