Abstract: Objective: To investigate the application value of 5G intelligent alarm system in the Intensive Care Unit (ICU) electrocardiogram (ECG) monitoring alarm management, so as to provide a reference for alarm management of critically ill patients. Methods: An intelligent alarm system for ICU ECG monitoring was developed based on 5G technology. The patients with conventional ECG monitoring in ICU of a tertiary grade A hospital in Hangzhou from July 1 to December 31, 2023 were selected as the control group, while the patients with 5G intelligent alarm system for ICU ECG monitoring from July 1 to December 31, 2024 were chosen as the observation group. The alarm response time, false alarm rate and nurse alarm fatigue before and after the application of the system were compared. Results: After the use of 5G intelligent alarm system, it was found that the alarm response time of the observation group [(103.52±51.00) s] was significantly shorter compared to that of the control group [(213.55±91.38) s]. The false alarm rate of the observation group (16.56%) was significantly lower compared to that of the control group (38.91%). The score of the nurse's alarm fatigue decreased significantly from 23.56±2.48 to 18.12±1.99. All differences were statistically significant (P<0.05). Conclusion: The intelligent alarm system for ECG monitoring based on 5G technology developed in this study not only improves the recognition and accuracy of ECG monitoring alarms, but also shortens the response time of nurses, and reduces the nurse's alarm fatigue, which is worthy of clinical popularization.
