OBJECTIVE: To identify and compare arm and forearm blood pressure measurements using appropriate cuff sizes versus a usual standard cuff. METHODS: A cross-sectional comparative study was used. Blood pressure was measured in 103 individuals using a 0.40 cuff width and 0.80 cuff length on both segments and followed by a measure with a usual standard cuff after one minute. Arm and forearm circumferences were measured at the middle point. RESULTS: Significant differences indicated overestimation of diastolic blood pressure in the forearm. These differences were lower than differences reported in other studies. Korotkoff sounds were improved after Forsberg's maneuver. CONCLUSION: Although, we found an overestimation of diastolic blood pressure in forearm, other studies suggest that the use of appropriate cuff sizes in the forearm derive more accurate measures of diastolic blood pressure. There is a need to study further measurements of blood pressure in the forearm.
