  9. Prevalence of end-digit preference in recorded blood pressure by nurses: a comparison of measurements taken by mercury and electronic blood pressure-measuring devices

    Prevalence of end-digit preference in recorded blood pressure by nurses: a comparison of measurements taken by mercury and electronic blood pressure-measuring devices

    Item type: Journal Article • Journal: South African Family Practice
    Objectives: When compared with the use of a mercury sphygmomanometer, the use of a validated digital blood pressure (BP) measuring device eliminates the risk of exposure to mercury. Digital devices are also associated with a lesser degree of end-digit preference...
