Description

OBJECTIVE: To compare the measurements of systolic and diastolic blood pressure obtained by auscultatory (mercury sphygmomanometer) and oscillometric (digital device Omron HEM-412C) methods.
METHODS: Participated in the study 22 older men (age: 67.4 ± 4.8 years; body mass: 79.4 ± 13.1 kg; stature: 1.7 ± 0.8 m), members of a program of regular exercise. The digital device Omron HEM-412C was connected in "Y" with the mercury sphygmomanometer. Three measures of blood pressure were obtained, with two minutes of interval between the measurements. Two "blind" evaluators recorded values of systolic and diastolic blood pressure.
RESULTS: The systolic and diastolic blood pressure measures obtained by auscultatory and oscillometric methods did not showed significant differences (p > 0.05). Positive and significant correlations between the methods were observed for systolic blood pressure (r = 0.96; p < 0.05) and diastolic (r = 0.91; p < 0.05). The mean differences (± standard deviation) systolic and diastolic blood pressure between both methods were 1.5 ± 5.4 mmHg e -0.2 ± 4.5 mmHg, respectively.
CONCLUSION: The results of this study indicate similarity in the measurements of systolic and diastolic blood pressure obtained by mercury sphygmomanometer and digital device Omron HEM-412C.
