Objective The aim of this study was to validate the Omron HBP-1300 oscillometric blood pressure (BP) device according to the British Hypertension Society validation protocol, in pregnant women of both medium-arm and large-arm circumferences.

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.
