PENGARUH LETAK TENSIMETER TERHADAP HASIL PENGUKURAN TEKANAN DARAH

Abstract

Background: Blood pressure is one of body vital signs that is used by doctors as a basis for patient’s diagnosis and therapy. Accurate measurement of blood pressure is needed in evaluating hemodynamic status of the patient and making diagnoses. Blood pressure is measured in mmHg and recorded in two different values: systolic and diastolic. Nowadays, there are varieties of sphygmomanometers, such as wall mounted sphygmomanometer and standing portable sphygmomanometer which are not equally located in height with the heart. Aim: The objective of this research was to prove that there is an effect of sphygmomanometer placement to systolic and diastolic measurement. Methods: This research is an analytic observational study using cross-sectional design. Subjects of the research were as many as 50 students with age ranging from 20 to 22. Measurements were carried out with sphygmomanometer located equal in height to the heart and above the heart, three times respectively. Sum of the three measurements was determined and analyzed using paired T-test. Results: The result of the data shows as follows systolic blood pressure with sphygmomanometer located equal in height to the heart vs above the heart (111,88 ± 12,91 vs 111,68 ± 11,86 mmHg) and diastolic blood pressure of sphygmomanometer located equal in height to the heart vs above the heart (65,38 ± 6,64 vs 65,06 ± 6,8 mmHg) Data analysis using paired t-test showed results of 0,835 for systolic blood pressure and 0,649 for diastolic blood pressure. Both results were not significant (p>0,05). Conclusions: There is no effect of sphygmomanometer placement to systolic and diastolic measurements.
