Objective: To explore the application effect of the problem-based learning (PBL) teaching model in the teaching of respiratory critical medicine. Methods: A total of 114 clinical medicine students who underwent internships in the Department of Respiratory and Critical Care Medicine of our hospital from January 2021 to December 2023 were randomly divided into a PBL group (n = 57) and a lecture-based learning (LBL) group (n = 57). The PBL group received PBL teaching, while the LBL group received traditional lecturing. Theoretical knowledge, clinical operation, case analysis abilities, and student satisfaction were compared between the two groups. Results: Compared with the LBL group, the PBL group showed significantly higher scores in theoretical knowledge, clinical operation, and case analysis (all P < 0.05). Student satisfaction was also markedly higher in the PBL group. Conclusion: The PBL teaching model effectively enhances students’ theoretical mastery, practical competence, and analytical thinking in respiratory critical medicine, improving teaching effectiveness and student satisfaction. It demonstrates high educational value and feasibility for broader implementation.
