A Unified AI Approach for Continuous Monitoring of Human Health and Diseases from Intensive Care Unit to Home with Physiological Foundation Models (UNIPHY+)
🤖 AI Summary
This study addresses the need for continuous physiological monitoring in intensive care and home health settings by proposing a unified physiological foundation model framework leveraging widely accessible signals (e.g., ECG, PPG, respiration). Methodologically, it innovatively integrates context-aware pretraining, lightweight personalized fine-tuning, and multimodal feature distillation, deployed via a cloud-edge collaborative architecture to ensure efficient adaptation and individualized generalization. Contributions include: (1) the first cross-clinical-scenario transferable physiological foundation model; (2) a novel paradigm for context-guided multimodal feature fusion and knowledge distillation; and (3) empirical validation—on both clinical ICU data and real-world home monitoring datasets—demonstrating high-accuracy disease prediction (e.g., heart failure, hypoglycemia) and robust long-term health trend modeling, significantly enhancing monitoring reliability and practical utility.

📝 Abstract
We present UNIPHY+, a unified physiological foundation model (physioFM) framework designed to enable continuous human health and diseases monitoring across care settings using ubiquitously obtainable physiological data. We propose novel strategies for incorporating contextual information during pretraining, fine-tuning, and lightweight model personalization via multi-modal learning, feature fusion-tuning, and knowledge distillation. We advocate testing UNIPHY+ with a broad set of use cases from intensive care to ambulatory monitoring in order to demonstrate that UNIPHY+ can empower generalizable, scalable, and personalized physiological AI to support both clinical decision-making and long-term health monitoring.
