Air exhaust, Measured pressure measurements and Calibration. RESULTS: Of the final sample of 76 sphygmomanometers, were unbalanced 76 sphygmomanometers, of which 56 (73, 7%) were of the aneroid type, 12 (15.8%) of the wall, 6 (7.9%) of the mobile column and 2 (2.6%) of mercury column, of the marks was predominant sphygmomanometers of the mark 1, with 30 (41.7%). Most of the analyzed sphygmomanometers had a serial number of 98.7% and a number of Inmetro 75%. A clamp-type relationship with calibration prevalence was found, with velcro clamps being 6 times more likely to be calibrated than clamp-type. CONCLUSION: The analysis was satisfactory in relation to the quality, calibration and general state of the apparatus, with new analyzes necessary for other variable variables to obtain a good blood pressure measurement.
