Accuracy of aneroid sphygmomanometer blood pressure recording compared with digital and mercury measurements in Brazil

Abstract

Digital, mercury and aneroid blood pressure measurements were carried out in 400 South American adults. There was slight under-reading of the aneroid instrument (hypertension prevalence 30%, compared with 32% for digital and mercury), but its robustness and simplicity makes it a suitable alternative to mercury machines in tropical field conditions. © 2004, SAGE Publications.
