The present study aimed to evaluate the accuracy of the Health & Life automated oscillometric upper-arm blood pressure monitor HL868ED for blood pressure monitoring according to the British Hypertension Society Protocol.
We recruited individuals until there were 85 eligible participants and their blood pressure could meet the blood pressure distribution requirements specified by the British Hypertension Society Protocol. For each individual, we sequentially measured systolic and diastolic blood pressures using a mercury sphygmomanometer (two observers) and the HL868ED device (one supervisor). Data analysis was carried out according to the British Hypertension Society Protocol.
The device achieved grade A. The percentage of blood pressure differences within 5, 10 and 15 mmHg was 68%, 91% and 98%, respectively, for systolic blood pressure, and 79, 96 and 99%, respectively, for diastolic blood pressure. The average (±SD) of the device-observer differences was −1.8 ± 6.0 mmHg for systolic and 0.1 ± 4.7 mmHg for diastolic blood pressures, respectively.
The Health & Life automated upper-arm blood pressure monitor HL868ED has passed the requirements of the British Hypertension Society Protocol, and hence can be recommended for blood pressure measurement in adults.
