Objective: To explore the participation experience, behavioral evolution, multidisciplinary collaboration, and practical dilemmas of gamified respiratory training for children with pneumonia from multiple perspectives (children, parents, rehabilitation therapists, nurses, and physicians). Methods: A phenomenological approach was adopted. Semi-structured interviews were conducted with 39 participants (15 children, 15 parents, 3 rehabilitation therapists, 3 nurses, and 3 physicians). Data were analyzed using Colaizzi's seven-step method. Results: Three themes and eight sub-themes were identified. Theme 1: Experience reshaping from "passive treatment" to "active player" (behavioral trajectory, age gradient of motivation, parental attitude change). Theme 2: Professional foundation and interdisciplinary collaboration model (three-tier strategy, three-party closed-loop collaboration). Theme 3: Multi-perspective barriers and sustainability dilemmas (high workload, collaboration vulnerability, home continuation gap). Conclusion: Gamified respiratory training has significant value in pediatric pneumonia rehabilitation. The three-party collaboration (therapist-nurse-physician) is key to ensuring quality but faces challenges including lack of standardization, insufficient human resources, and difficulties in home continuation.
