New deep learning model estimates cardiac output from PPG signals

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel deep learning model called CVAF-Net for estimating cardiac output from short photoplethysmography (PPG) signals. This model processes both raw PPG data and a feature sequence map, fusing them using cross-view attention to improve accuracy. CVAF-Net demonstrated strong performance across multiple datasets, achieving a mean absolute error of 0.19 L/min on simulated data and outperforming most benchmarks while being significantly more computationally efficient than a leading Transformer-based model.

    Cross-View Attention Fusion Net: A Prior-Guided Dual-View Representation Learning for Cardiac Output Estimation from Short-Term PPG Signals

    Accurate cardiac output (CO) estimation from photoplethysmography (PPG) is promising for unobtrusive hemodynamic monitoring, but remains difficult since CO is jointly determined by cardiac function and vascular tone. Conventional feature-based models use physiologically meaningfu…
