One In Seven BP Monitors Fails To Meet British Hypertension Society Standard

One in seven blood pressure monitors fails the British Hypertension Society standard, according to a study published in the British Journal of General Practice (2011;61:564).

The study focused on the validation of mercury, digital and aneroid sphygmomanometers, comparing the accuracy of those in current use with those used previously.

Mercury and electronic sphygmomanometers were found to be more accurate than aneroid devices for measuring blood pressure (P=0.001). Overall, 86 per cent of the 584 monitors tested met the reference BHS standard (deviation of ≤3mmHg); 95 per cent, 88 per cent and 78 per cent of mercury, digital and aneroid, respectively, met the standard, leaving the researchers to conclude that mercury sphygmomanometers are the most accurate with aneroid devices falling significantly short in comparison.
