Abstract
An educational sphygmomanometer that could visualize pressure reduction speed and measurement values was developed to allow nursing students to acquire blood pressure measurement skills. Although Device No. 3, which was successively modified from the original Device No. 1, showed effectiveness in the technical acquisition of skills associated with depression speed, it was not effective in the acquisition of skills for listening to Korotkoff sounds, thereby suggesting low measurement value detection precision. Therefore, Device No. 4 was developed with enhanced measurement value detection precision and its educational effects were investigated. The subjects were first-year nursing students；Device No. 3 was used by 58 students (hereinafter, Device No. 3 group) , and Device No. 4 was used by 54 students (hereinafter, Device No. 4 group) . Similar to the Device No. 3 group, effects were observed for depression speed measurement in the Device No. 4 group. The Device No. 4 group could listen to Korotkoff sounds more precisely than the Device No. 3 group (P＜0.05) . The increased measurement value detection accuracy with the educational sphygmomanometer Device No. 4 enabled students to accurately review their skills, leading to effective training.
