Comparing Blood Pressure Values Obtained by Two Different Protocols: National Health and Nutrition Examination Survey, 2017-2018.

Objectives Blood pressure (BP) is traditionally measured using a mercury sphygmomanometer. Given environmental concerns about mercury, clinical and survey settingsare moving to automated devices with an oscillometric protocol to obtain BP. This report compares BP measurement using the mercury and oscillometric protocols.
