A Comparative Study between Digital, Aneroid and Mercury Sphygmomanometers

This study evaluates the accuracy of digital and aneroid sphygmomanometers compared to the traditional mercury sphygmomanometers, with a focus on potential replacements that are less harmful to the environment.Conducted in a multispeciality hospital in Ahmedabad, India, over a one -month period, the research involved 101 non -hypertensive individuals aged 18 to 30 years.Measurements were taken using all three types of sphygmomanometers, and the data analyzed using SPSS software.The findings indicate no significant difference in mean systolic blood pressure measurements across the devices, while the differences in mean diastolic measurements were significant between mercury and digital, and highly significant between mercury and aneroid sphygmomanometers.The study concludes that with regular calibration against a mercury standard, both digital and aneroid devices can serve as viable, environmentally friendly alternatives for blood pressure measurement in community settings.
