Abstract

Aim- Aim of our study is to measure the BP by using all the three devices to find out the standard difference of BP between them. Objectives- Comparison of BP recordings, measured using mercury Sphygmomanometer, aneroid Sphygmomanometer and automated devices. Material and method- the study was conducted on normal healthy subjects between the age group of 18 to 25 years (MBBS and NURSING students) of Amala Medical sciences Kerala. We recorded the BP of all the healthy subjects using three different BP measuring devices (mercury, aneroid and automated BP apparatus) with gap of 5 minutes between the readings. Statistical analysis- independent “t” test was used for the analysis. Results-there was a significant difference (p<0.0001) among the SBPs and DBPs recorded by all the three devices except SBP of mercury and automated were the significant difference was less (p<0.05). Conclusion- After comparing the SBP and DBP by above three devices, we concluded that mercury shows higher reading compared to aneroid and automated devices and aneroid is showing lower values compared to mercury and automated.
