Objective To explore the effects of a systematic training of airway management ability of the junior nurses in the Intentive Care Unit（ICU）. Methods The airway management training group was set up to systematically train 54 junior ICU nurses. The theory teaching was combined with online teaching and offline salons. The bedside teaching，guidance and situation simulation were also used. Cases of adverse events related to airway management were analyzed. The airway management ability was compared before and after the intervention. Results After the training，the scores of sucking ability of junior nurses were higher than those before the intervention（t=3.911，P=0.003）. The qualification rate of airbag management was higher than that before the intervention（ χ2=66.799，P<0.001）. The qualification rate of humidification management was higher than that before the intervention（ χ2=10.581，P=0.001）. Conclusion The systematic training has effectively improved the airway management ability of ICU junior nurses.
