Warn patients about small blood pressure monitors

Finger-type electronic blood pressure monitors are less accurate and consistent than arm and wrist types, a recent study reports. Researchers tested 13 models of blood pressure gauges, priced between $880 and $1,480, and compared readings on them with those on the mercury-type blood pressure gauge. The results varied among models, but some arm and wrist types were found more accurate and consistent than those used on fingers. The finger types had greater deviations, with some of the systolic readings differing by more than 10 mmHg on average.
