Purpose: We gathered information for the development of a blood pressure measurement education program by analyzing the accuracy of reading taken using a blood pressure simulator by Korean paramedic students. Methods: Data from 131 students were collected in November 12-20, 2013, and April 2-4, 2014. A 27-item questionnaire was administered, the accuracy of measurements confirmed using a blood pressure simulator (BT-CEAB), and the data analyzed (SPSS v 21.0). Results: The accuracy of systolic and diastolic blood pressure readings (${\leq}2mmHg$) was relatively low (27.5%). The mean blood pressure knowledge score was 67.61 points; significant differences were noted considering the sex (p = .001), hours of practice (p =.007), numbers of practice (p = .001), and reported self-confidence (p = .026). The blood pressure measurement accuracy group did not show a significant difference in its knowledge of blood pressure (p = .198). Conclusion: Most subjects needed several practice sessions to master the skill of measuring blood pressure. The feedback provided by individual assessment and the practice education program will serve as the basis for clinical and prehospital practice.
