Comparison of radialis sphygmomanometer in evaluating the blood pressure of healthy volunteers

In this study, we compared the blood pressure measurement that obtained by a radialis sphygmomanometer with two others non-invasive sphygmomanometer types i.e. an aneroid sphygmomanometer and a brachial sphygmomanometer. The aim of this study was to evaluate statistically the blood pressure values of a radialis sphygmomanometer relative two other types of sphygmomanometer. This study was performed as a validation test before modifying the existing display-based radialis sphygmomanometer to a voice-based radialis sphygmomanometer. By developing the radialis sphygmomanometer with voice output, we believed that a blind people can be possible to measure the blood pressure easily, independently and periodically. To collect the data measurements, an experience nurse measured two blood pressure values i.e. systolic and diastolic of 30 healthy adult volunteers (17 female, 13 male; mean age 40.87±13.97 years, range: 16-75 years) with three diffent types of sphygmomanometer. A mercury sphygmomanometer was used at first and continued by a brachial sphygmomanometer and a radialis sphygmomanometer in order. Data were then analyzed statically using one way ANOVA in SPSS 18. The statistic results showed that the average measurement values were equal among three types of sphygmomanometer with significance (α) of systole and diastole bigger than 0.05 i.e. 0.055 and 0.178, respectively.
