Does the Omron 705IT automated blood pressure monitor accurately measure blood pressure compared to mercury sphygmomanometers according to BHS and AAMI criteria?
The Omron 705IT automated blood pressure monitor is highly accurate and meets BHS and AAMI validation criteria, making it suitable for professional and home use.
Effect estimate: Mean difference 0.60 mmHg (systolic) and -3.15 mmHg (diastolic)
BACKGROUND: The Omron 705IT (HEM-759-E, Omron Corporation, Kyoto, Japan) is an automated oscillometric upper arm blood pressure monitor for the professional and home use markets. The aim of this study was to validate the accuracy of this device according to the British Hypertension Society and the Association for the Advancement of Medical Instrumentation SP10 validation criteria. METHODS: Study participants were recruited until a total of 85 were obtained that filled the blood pressure categories specified by the British Hypertension Society protocol. Recruitment to the study was from the general medical and specialist clinics and from the staff at Guy's & St Thomas' Hospital in London, UK. Nine sequential same-arm blood pressure readings were taken from each participant by two trained observers, alternating between mercury reference sphygmomanometers and the Omron 705IT (HEM-759-E). The differences between the reference and test device readings, for both systolic and diastolic pressures, were compared with British Hypertension Society and Association for the Advancement of Medical Instrumentation criteria to determine the outcome of the study. RESULTS: The Omron 705IT (HEM-759-E) is graded 'A' for systolic and 'A' for diastolic blood pressures according to the British Hypertension Society criteria. The mean (standard deviation) of the difference between the observer and the device measurements was 0.60 (6.0) mmHg for systolic and -3.15 (6.6) mmHg for diastolic pressures, respectively. The device, therefore, also satisfies the Association for the Advancement of Medical Instrumentation SP10 standard, that requires differences of less than +/-5 (8) mmHg. CONCLUSIONS: The Omron 705IT (HEM-759-E) achieved an 'A/A' performance classification under the British Hypertension Society criteria and passes the Association for the Advancement of Medical Instrumentation requirements for the study population. It can be recommended for professional and home-use in an adult population.
Coleman et al. (Wed,) conducted a observational in Blood pressure (n=85). Omron 705IT (HEM-759-E) vs. Mercury reference sphygmomanometers was evaluated on Accuracy according to the British Hypertension Society and AAMI SP10 validation criteria (Mean difference 0.60 mmHg (systolic) and -3.15 mmHg (diastolic)). The Omron 705IT (HEM-759-E) achieved an 'A/A' performance classification under BHS criteria and passed AAMI requirements, with mean differences of 0.60 mmHg (systolic) and -3.15 mmHg (diastolic).
