Validation of Omron HBP-1300 professional blood pressure monitor based on auscultation in children and adults

Abstract

Backgroud: To determine whether the professional Omron HBP-1300 blood pressure (BP) monitor meets American Association for the Advancement of Medical Instrumentation (AAMI) accuracy standards in Chinese children and adults. Method: According to the AAMI protocol, simultaneous auscultatory measurements by two observers using a mercury manometer were obtained in participants using the Omron HBP-1300. Triple measurements were obtained after a minimum 5-min rest with a 1-min interval between adjacent measurements. Results: A total of 85 participants submitted to 255 doctor-measured BP and 255 successful professional monitor readings. The initial auscultation systolic BP was <100 mmHg in 25 participants (29.4 %), 100-160 mmHg in 53 participants (62.4 %), and >160 mmHg in seven participants (8.2 %). All of the simultaneous measurements agreed to within ±10 mmHg, while 95 % agreed to within ±4 mmHg for both systolic and diastolic BP, and the consistency between two observers was satisfactory. The difference between the devices was -1.3 ± 3.6 mmHg for systolic BP and 0.7 ± 3.8 mmHg for diastolic BP and by AAMI method 1, which met this guideline. The average difference between two devices by AAMI method 2 was 1.4 ± 3.2 mmHg for systolic BP and 1.0 ± 3.9 mmHg for diastolic BP, which met this guideline. Conclusion: The professional BP monitor Omron HBP-1300 is desirable for measuring the BP for Chinese children and adults.
