Optimisation Hémodynamique Prédictive et Alerte Clinique Multiparamétrique

VitalOpt transforme les flux physiologiques bruités au chevet du patient en hémodynamique prédictive d'une clarté absolue, alertant les réanimateurs d'un choc septique imminent ou d'un collapsus circulatoire des heures à l'avance.

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)

Combattre la dégradation clinique et la fatigue des alarmes en soins intensifs

Hospital intensive care units suffer from high false alarm rates exceeding 80%, desensitizing nursing teams. VitalOpt uses signal quality indices (SQI) and multi-signal physiological correlation to validate genuine clinical distress and optimize organ perfusion.

Core Engineering Areas

Arterial Line & Pleth Quality Scoring — Preventing life-threatening clinical mismanagement caused by damped arterial lines and motion artifacts.
Automated NEWS2 Scoring — Replacing intermittent paper vital signs checks with continuous automated scoring to arrest cardiopulmonary arrest.
