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

UNLABELLED BACKGROUnD: 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.
