ABSTRACT Objective: to produce and validate an educational video on the procedure of indirect blood pressure measurement with the oscillometric technique to support actions of blood pressure screening programs in Brazil. Method: a methodological study consisting in three stages: 1) pre-production of a script/storyboard; 2) content validation by a committee of 16 experts recruited according to their degrees and training in the area of interest of the study; and 3) final production, recording and edition of the educational video. For data collection, three validated instruments were used that allowed the video to be assessed as to its functionality, usability, efficiency, relevance, verbal language, audiovisual technique, environment, content and proposed objectives. The analysis of the quantitative variables was performed by calculating absolute and relative frequencies, and the categorical variables were measured using means and standard deviations. Items that obtained a CVI > 0.75 were considered valid. Results: script validation was performed by eight experts and obtained a CVI of 0.93, while the technical assessment of the educational video and storyboard was performed by three experts and obtained a CVI of 0.97. After accepting the experts' suggestions, the educational video was produced and validated by eight experts, who considered the material valid for application (CVI = 0.94). Conclusion: the educational video produced and validated in this study was characterized as an appropriate strategy for teaching the indirect measurement of blood pressure with the oscillometric technique among health professionals who volunteer to participate in blood pressure screening programs in Brazil.
