Abstract In a continuing study of the accuracy of aneroid sphygmomanometers we examined the factors with the most influence on these popular instruments. Our previous study tested the accuracy of recently-purchased aneroid sphygmomanometers with regard to the variables of instrument age, frequency of use and brand. The current study examined older and more heavily-used instruments utilized for several years by students and practitioners. We tested 50 aneroid sphygmomanometers at 10 mmHg intervals from 300 to 0 mmHg using a mercury column sphygmomanometer as a standard. Age and frequency of use were found to be factors which can decrease the accuracy of aneroid sphygmomanometers. Brand is also an important consideration; as, some brands were tremendously inaccurate even when new. Important recommendations emerged in regard to selection and maintenance of aneroid sphygmomanometers both for practitioners and colleges of optometry.
