Aneroid Sphygmomanometer for Hospital: Hypertension is one of the majorpublichealthproblem affecting the wholeworld so its accuratedimension is of utmostsignificance for its earlyopinion and operation. Enterprisesrelated to the implicitillgoods of mercury on health and terrain, has led to the wideuse ofnon-mercury sphygmomanometers.
A studywasconducted to compare the delicacy of readings of aneroid and digital sphygmomanometers in reference to mercury sphygmomanometers and determine the hypertensive bracketagreement between the mercury andnon-mercury bias.
The studywasconducted in an OPD of a healthcentre in a pastoralcommunity of West Bengal which is the pastoralfieldpracticearea of our institute. An aneroid and a digital sphygmomanometer were compared to a duly calibrated mercury sphygmomanometer. All the subjects above the age of 25 times, in two days per week, namedaimlessly from five workingdays per week in a period of one month were named. Two bloodpressurereadings of each of 218 studysubjectswasrecorded with each pretested sphygmomanometer. Mated t- test, Kappa portions, perceptivity and particularitytests were done. Receiver Operating Characteristics windanalysiswasdone and Youden indicatorwasestimated to descry the optimal cut off point for the opinion of hypertension bynon-mercury sphygmomanometers.
Data analysis of 218 studysubjectsshowed the mean difference of the mercury reading and the testdevicewasmuchlower for aneroid than that of the digital device for both systolic and diastolic bloodpressure. Further than 89 of aneroid readings and lower than 44 of the readings by digital devicehadabsolutedifference of 5 mm Hg. when compared with the mercury readings for both systolic and diastolic bloodpressure. Perceptivity and particularity of aneroid devicewasadvanced (86.7 and98.7) than digital device (80 and67.7). Receiver Operating Characteristicwindhadlargerarea under the wind for aneroid device than digital device for both SBP and DBP.
The Aneroid Sphygmomanometer for Hospital had better delicacy than the digital device as compared to mercury sphygmomanometer and should beused for proper and better operation.
