OBJECTIVE: The present study aimed to evaluate the accuracy of the fully automated oscillometric upper-arm blood pressure monitor TM-2656 according to the British Hypertension Society (BHS) Protocol 1993. METHODS: We recruited individuals until there were 85 eligible participants and their blood pressure could meet the blood pressure distribution requirements specified by the BHS Protocol. For each individual, we sequentially measured the systolic and diastolic blood pressures using a mercury sphygmomanometer (two observers) and the TM-2656 device (one supervisor). Data analysis was carried out according to the BHS Protocol. RESULTS: The device achieved grade A. The percentage of blood pressure differences within 5, 10, and 15 mmHg was 62, 85, and 96%, respectively, for systolic blood pressure, and 71, 93, and 99%, respectively, for diastolic blood pressure. The average (±SD) of the device-observer differences was -2.1±7.8 mmHg (P<0.0001) and -1.1±5.8 mmHg (P<0.0001) for systolic and diastolic blood pressures, respectively. CONCLUSION: The A&D upper-arm blood pressure monitor TM-2656 has passed the requirements of the BHS Protocol, and can thus be recommended for blood pressure measurement.

Zeng et al. (2013) reported a cross-sectional. A&D TM-2656 blood pressure monitor vs. Mercury sphygmomanometer was evaluated on Device-observer blood pressure differences according to the BHS Protocol 1993 (MD -2.1 mmHg, p=<0.0001). The A&D TM-2656 blood pressure monitor achieved BHS grade A, with average device-observer differences of -2.1±7.8 mmHg for systolic and -1.1±5.8 mmHg for diastolic pressure.
