Background: The Ventriloscope® (Lecat's SimplySim, Tallmadge, OH) is a modified stethoscope used as a simulation training device for auscultation. Objective: To test the effectiveness of the Ventriloscope as a training device in teaching heart and lung auscultatory findings to paramedic students. Methods: A prospective, single-hospital study conducted in a paramedic-teaching program. The standard teaching group learned heart and lung sounds via audiocassette recordings and lecture, whereas the intervention group utilized the modified stethoscope in conjunction with patient volunteers. Study subjects took a pre-test, post-test, and a follow-up test to measure recognition of heart and lung sounds. Results: The intervention group included 22 paramedic students and the standard group included 18 paramedic students. Pre-test scores did not differ using two-sample t-tests (standard group: t [16] = -1.63, p = 0.12) and (intervention group: t [20] = -1.17, p = 0.26). Improvement in pre-test to post-test scores was noted within each group (standard: t [17] = 2.43, p = 0.03; intervention: t [21] = 4.81, p < 0.0001). Follow-up scores for the standard group were not different from pre-test scores of 16.06 (t [17] = 0.94, p = 0.36). However, follow-up scores for the intervention group significantly improved from their respective pre-test score of 16.05 (t [21] = 2.63, p = 0.02). Conclusion: Simulation training using a modified stethoscope in conjunction with standardized patients allows for realistic learning of heart and lung sounds. This technique of simulation training achieved proficiency and better retention of heart and lung sounds in a safe teaching environment. © 2012 Elsevier Inc.
