Validation of the A&D UA-705 device for self-measurement of blood pressure according to the British Hypertension Society protocol.
OBJECTIVE
We tested the accuracy of the UA-705 blood pressure semi-automatic monitor.


METHODS
Device evaluation was performed according to the modified British Hypertension Society protocol released in 1993. Eighty-five patients with characteristics outlined in the British Hypertension Society protocol were recruited among those attending our out-patient clinic. Sequential readings were taken for the main validation test. Outcome was classified according to the British Hypertension Society criteria, which are based on four zones of accuracy differing from the mercury standard by 5, 10 and 15 mmHg, or more.


RESULTS
The mean blood pressure difference (+ or -1 SD) between device and observers was 0.4 mmHg (SD 7.7) for systolic blood pressure and 0.3 mmHg (SD 8.2) for diastolic blood pressure. Overall, 96% (observer 1) and 95% (observer 2) of readings between device and observers differed by 15 mmHg or less for both systolic and diastolic blood pressure. The device achieved a grade A for both systolic and diastolic blood pressure.


CONCLUSIONS
This study shows that the A&D UA-705 device satisfies the British Hypertension Society standard for accuracy by achieving a grade A for both systolic and diastolic blood pressure.
