There is an outsized marketplace for a vital sign of blood pressure measuring device not only in clinical medicine but also among the general public where the demand for self-measurement of the vital signs is growing rapidly. For consumers, whether medical or lay, accuracy should be of prime importance when selecting a tool to live a vital sign.
However, most devices haven’t been evaluated for accuracy independently using the 2 most generally used protocols: British Hypertension Society (BHS) protocol and therefore the standard set by the US Association for the Advancement of Medical Instrumentation (AAMI).1,2
The Working Group on Blood Pressure Monitoring of the European Society of Hypertension has decided to review blood pressure measuring device regularly to guide purchasers.3 For this first report devices that there’s published evidence of independent validation using these protocols are surveyed.
Because most vital sign devices haven’t been independently validated, only a fraction of the various devices available is surveyed. Devices that have been validated recently for which results have not yet been published were not included, but this shortcoming should be addressed in the future.
Summary Points of Blood Pressure Measuring Device
Two manual sphygmomanometers have been validated, one is recommended
Five devices for clinical use in hospitals have been validated, two are recommended
23 devices for self-measurement of blood pressure have been validated, five are recommended
24 devices for ambulatory measurement of blood pressure have been validated, 16 are recommended Identification of devices.
This review was based on two previous surveys (which should be consulted for early validation studies that are not reproduced in this review),7,8 and computerized search programs were used to identify validation studies in the literature published up to December 1999.
Blood pressure measuring device were divided into two broad categories: manual sphygmomanometers, which include mercury and aneroid devices; and automatic sphygmomanometers, which include devices for clinical use in hospitals, for self-measurement of blood pressure, for ambulatory blood pressure measurement, and for measuring blood pressure in community settings.
