Architectural Layers & Regulatory Standards

• Continuous Biosignal Preprocessing (Zero-Phase Bandpass Filters / Notch 50/60 Hz / Dicrotic Notch Detectors): High-frequency sampling of arterial blood pressure (ABP), photoplethysmography (PPG), and central venous pressure (CVP).
• Morphological Signal Quality Indexing (SQI Waveform Scorer / Fuzzy Logic Artifact Discriminator): Dynamic assessment of motion artifacts, catheter whipping, and damped pressure lines preventing spurious calculations.
• Hemodynamic Parameter Synthesis (Pulse Contour Analysis (Wesseling Model) / Windkessel 3-Element Core): Mathematical extraction of stroke volume variation (SVV), pulse pressure variation (PPV), and total peripheral resistance (TPR).
• Predictive Shock & Deterioration Alerting (Recurrent LSTM Predictor / NEWS2 Clinical Deterioration Gateway): Multi-lead physiological fusion predicting hypotensive episodes and septic deterioration up to 4 hours in advance.

Key Metrics: 82% (False Alarm Reduction) | 4 Hours (Early Warning Lead Time) | 99.4% (Cardiac Output Correlation) | < 15 ms (Real-Time Waveform Latency)
