Abstract:
Background: Sphygmomanometer is an instrument used for measuring blood pressure Currently the commonly used sphygmomanometers are digital sphygmomanometers, and manual sphygmomanometers. For correct estimation of blood pressure in non-invasive setting mercury sphygmomanometers were considered as gold standard for long. After favoring the use of manual sphygmomanometers, the studies have found it to be more accurate compared to digital sphygmomanometers.
Methodology: Cross section Hospital-based study was conducted among Bugando medical center outpatients at medical clinic, specifically gastroenterology clinic. The readings were recorded in the checklist designed so as to allow the statistical comparisons of the readings. After data collection the data was sent to the excel for clearing and coding. Then analyzed by using SPSS version 20.1 and the results was presented statically by using mean standard deviation, frequencies and tables.
Results: The results of this study comprised of females and males mean (±s.d.) 1.5±0.5 age 44 ±15. Individual readings for systolic and diastolic BP for each of the two methods were tabulated and displayed as mean and mean standard deviation (figure 1). Mean (±s.d.) BP taken with the first readings manual device was 125 ± 16/79 ± 12 mm Hg, second readings manual device was 126±17/79±11 compared to 127 ± 14/78 ± 11 mm Hg for the digital first BP readings, 126±15/79±11 second readings digital devices. Parameters such as age, sex, and cuff size did not predict the differences in systolic and diastolic BP between the automated and manual measurements.
Conclusion: This study concluded that the manual blood devices are reliable and accurate in measurement of blood pressure in adults due to small difference in mean and mean standard deviation between first and second manual readings compared to the first and second digital readings also we can use the device for measuring blood pressure in clinical areas such as OPD department and in-patient department IPD for accurate and reliable blood pressures readings also the study concluded that factors like age sex and difference arms size does not produce significant effect during blood pressures measurements .
