Establishing AI-driven evaluation standards and human-in-the-loop guidance for digital first aid education: a perspective.

Short-form video platforms are now primary channels for public acquisition of medical and first-aid knowledge, including cardiopulmonary resuscitation (CPR) and the Heimlich maneuver. However, content on these platforms is mainly influenced by recommendation algorithms rather than evidence-based medical standards, resulting in the risk of erroneous procedural demonstrations that may cause severe secondary injuries. This Perspective introduces a novel digital public health paradigm: by establishing standardized digital evaluation systems and integrating computer vision (CV) with multimodal artificial intelligence (AI), short-form video platforms can transition from unidirectional "knowledge dissemination media" into bidirectional ecosystems of "intelligent assessment and professional guidance." Specifically, this framework proposes operationalizing natural language processing (NLP) to audit instructional content against clinical guidelines, and CV to track critical kinematic thresholds (e.g., maintaining 171°-180° elbow flexion and >5 cm compression depth) to automatically filter erroneous instructions. Additionally, it presents a bifurcated dynamic response model that strictly distinguishes between routine training (utilizing real-time error correction) and unexpected emergencies (mandating "Human-in-the-Loop" telemedicine intervention). The discussion concludes with an in-depth examination of the ethical imperatives related to medical device regulation, legal liability, and algorithmic equity.
