Objective: This work focus is analysis of the physical and calibration conditions of the sphygmomanometers used at the Itajubá school hospital. Method: A quantitative, observational, cross-sectional study was performed with data collection of all aneroid and mercury sphygmomanometers from the institution, excluding those that were not in use or not belonging to the School Hospital. The analyzed variables were: Identification, Gauge, Clamp, Pear, Deflation valve, 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.
