40至55岁是心脏易损期猝死高发，专家呼吁发动外卖小哥建立急救网络

Core Viewpoint - The recent death of "internet celebrity teacher" Zhang Xuefeng has sparked widespread attention on the issue of sudden cardiac death, particularly among young people, highlighting the need for improved emergency response systems and public awareness of heart health [3][4]. Group 1: Sudden Cardiac Death in Young People - Sudden cardiac death is increasingly prevalent among young individuals, particularly during the "vulnerable period" between ages 40 and 55, due to factors like unstable plaques and sudden blood pressure spikes [3]. - Approximately 540,000 cases of sudden cardiac death occur annually in China, often preceded by symptoms such as chest discomfort and arrhythmias [3]. Group 2: Emergency Response and AED Utilization - Despite the installation of Automated External Defibrillators (AEDs) in public places, their actual usage remains low due to limited training and legal concerns [4]. - There is a proposal to leverage the presence of delivery personnel and ride-hailing drivers to create a more extensive emergency response network, with training and incentives for these individuals to use AEDs [4]. Group 3: Community Involvement in Emergency Services - Initiatives are underway to integrate delivery workers and ride-hailing drivers into the emergency response system, with training programs being developed to equip them with lifesaving skills [4]. - The "Didi Car-mounted AED Volunteer Service" project aims to recruit qualified ride-hailing drivers to serve as mobile emergency response nodes by equipping their vehicles with AEDs [4]. Group 4: Broader Implications of AED Accessibility - Experts suggest that making AEDs more accessible in private vehicles could enhance public awareness of emergency response and increase the likelihood of successful resuscitation during critical moments [5].
