Mechanism, contributing factors, and coping strategies of alarm fatigue in intensive care nursing: a qualitative study

Cognitive load as a mechanism linking the interaction between alarm response demands and available resources in the development of alarm fatigue among ICU nurses. To mitigate alarm fatigue, it is essential to reduce the intensity of alarm demands while enhancing resource support to relieve cognitive load. Organizational efforts should optimize alarm systems, establish formal protocols, and provide comprehensive training. Teams should reinforce collaboration and mutual support. Individually, nurses are encouraged to enhance psychological self-regulation and maintain sufficient sleep and physical health.
