In the high-stakes domain of intensive care units (ICUs), where patient conditions evolve rapidly through continuous streams of physiological signals, there is a pressing need for advanced intelligence frameworks that can interpret temporal patterns without relying on empirical data processing. This conceptual manuscript proposes the temporal signal adaptive resonance topology (TSART), a novel architectural design for orchestrating signal intelligence in continuous ICU monitoring environments. TSART integrates layered modules for signal temporality capture, adaptive resonance mapping, and feedback-driven orchestration, emphasizing theoretical interoperability with electronic health records (EHRs) and decision support pipelines. By synthesizing recent literature on clinical AI architectures and healthcare analytics infrastructures, we outline how TSART addresses governance challenges, such as drift sensitivity and resource allocation, through interpretive formulas modeling decision latency and monitoring burden. The framework fosters seamless clinical workflow integration, mitigating human-AI interaction frictions in real-time environments. Without empirical validations, this work highlights theoretical implications for enhancing ICU vigilance, including reduced cognitive overload for clinicians and optimized signal governance. Ultimately, TSART represents a blueprint for future intelligence ecosystems that prioritize temporal fidelity and systemic resilience in critical care settings.

This systematic review examines the use of edge artificial intelligence (AI) and wearable sensors for real-time patient monitoring in smart hospitals and home settings, focusing on detecting deterioration, falls, arrhythmias, and infection-related changes. The review synthesizes studies from 2017 to 2026 on edge AI architectures, wearable sensor fusion, and clinical alert systems, emphasizing latency, power constraints, alert performance, and integration into clinical workflows. A PRISMA 2020-compliant search identified 127 studies from 2,100 records, with findings showing that while edge AI execution grew post-2020, it still represented a minority of designs. Sensor fusion was often linked to broader event coverage but increased implementation complexity. The review concludes that edge AI can reduce latency and enhance privacy but introduces challenges related to power usage, model complexity, device reliability, and maintenance, with limited clinical validation of alert systems and few studies addressing alert fatigue or clinician response.
