A new evaluation framework for blood pressure estimation using photoplethysmography (PPG) has been developed, focusing on change point detection rather than aggregated metrics. This approach identifies abrupt shifts in blood pressure trajectories to assess model performance during fluctuations. The study found that current state-of-the-art models degrade significantly around these change points, and proposes a targeted re-calibration method to improve robustness. AI
IMPACT This research could lead to more reliable continuous blood pressure monitoring systems by improving the accuracy of AI models during dynamic physiological changes.
