<p><b>OBJECTIVE:</b> Compare and verify the agreement of measurements of blood pressure systolic (SBP) and diastolic (DBP) obtained by auscultatory methods (mercury column) and oscillometric (Omron - 412C), in elderly women.<br> <b>METHODS:</b> Three blood pressure (BP) measurements by two minutes intervals were measured from 47 elderly (66.8 ± 5.3 years). The oscillometric device was connected in "Y" with the mercury sphygmomanometer and the SBP and DBP values were recorded by two evaluators "blinded".<br> <b>RESULTS:</b> For each device, significant differences were not observed (P &lt; 0.01) between measurements (1, 2 and 3) SBP and DBP Except for the second measure of PAD, statistically significant differences (P &gt; 0.01) were identified from the mean SBP and DBP, estimated by different methods. Although significant positive correlations (P &lt; 0.01) e high magnitude were identified between the two methods investigated for SBD (r = 0.891) and DBP (r = 0.813), concordance analysis indicated relatively large limits. The SBP was underestimated by up to 23.1 mmHg or overestimated of up to 12.8 mmHg and in DBP was underestimated by up to 13.4 mmHg or overestimates of up to 9.0 mmHg for oscillometric method in the face of auscultation.<br> <b>CONCLUSION:</b> The results of this study suggest that SBP and DBP appear to be influenced by using different methods of evaluating BP</p>
