ABSTRACT
OBJECTIVE: To investigate the use of high fidelity simulation mannequins in improving competence and confidence levels of medical students to recognize cardiac and lung sounds. Study design: Observational study. SUBJECTS and METHODS: The students took a pre-test evaluating their ability to recognize cardiac and respiratory sounds. They then rotated through three clinical scenarios using simulation mannequins. They were then given a post-test. Both prior to, and following the session the students completed a Likert scale on their comfort in recognizing the sounds. The pre- and post-test scores were compared. RESULTS: There was a significant improvement in the students' ability to recognize cardiac and respiratory sounds (p<0.0001), as well as in their comfort levels (p<0.0001). Overall, 80% of the studnets felt more comfortable in their ability to recognize the sounds, 17% felt the same and 3% felt less comfortable. CONCLUSION: Use of simulation mannequins improves medical students' abilities, as well as comfort in recognizing cardiac and respiratory sounds.
