Objective To explore effective training methods for inhalation therapy among respiratory nurses.Methods A total of 44 respiratory nurses were divided into a control group of 21 and an intervention group of 23 according to working wards. The control group received conventional theoretical and operational training, while the intervention group additionally participated in scenario simulations and knowledge competitions. The scores of inhalation therapy knowledge, attitude, and practice （KAP）, inhalation therapy guiding ability and the nurses′ satisfaction towards the training were compared between the two groups before and after the training.Results After the training, the scores of inhalation therapy KAP, inhalation therapy guiding ability and the nurses′ satisfaction towards the training in the intervention group were significantly higher than those of the control group （all P＜0.05）.Conclusion Applying scenario simulations and knowledge competitions in inhalation therapy training for respiratory nurses can effectively improve the training outcomes.
