Abstract Background Arterial hypertension affects around 30% of the Brazilian adult population, showing a direct and progressive relationship with an increased risk of cardiovascular diseases (CVDs). In this context, adjustments in the calibration and physical constitution of sphygmomanometers are essential conditions for obtaining correct blood pressure (BP) measurements. Objectives Analyze the profile and quality of sphygmomanometers used in various sectors of a health education institution in Belo Horizonte, Minas Gerais. Methods The present study conducted a cross-sectional, observational, and non-interventional study to assess adherence to various quality parameters of the sphygmomanometers available in the outpatient clinic, emergency department, and ward of an educational institution in the municipality of Belo Horizonte. Results We analyzed 78 devices, in which high rates of adherence were identified for velcro/pins, 93.5% (73/78); bulbs/rubbers, 92.1% (70/76); valves, 93.4% (71/76); the seal of the National Institute of Metrology, Quality, and Technology (INMETRO), 97.4% (76/78); and the clock, 92.1% (70/76). However, these parameters showed no statistical significance. Institutions (hospital/outpatient clinic) recorded higher calibration rates, 75% (39/52, p<0.001), in accordance with the deadlines stipulated by INMETRO, and the cuff/equipment compatibility showed its highest value (52%) among students (32/61, p = 0.004). Conclusion Our study showed that 38.4% (30/78) of the devices did not presented some type of inadequacy, with outpatient-owned devices had the highest compliance rate (p = 0.015). These findings are worrisome, as they can lead to inaccurate BP measurements. 30 population CVDs. CVDs .
