ReviewOscillometric sphygmomanometers: a critical appraisal of current technology.
Blood pressure (BP), a key vital sign, monitors general health. Oscillometric devices are increasingly used for measurement, although their accuracy continues to be critically debated. A functional block diagram is used to review the components that affect accuracy. ⋯ The indirect nature of BP measurement poses particularly problems for ensuring accuracy. Critical assessment has done much to improve standards, but a solid theoretical understanding of the technique has not been formulated and further work is required.
