852
Unique Features Extracted per Cardiac Cycle for Enhanced ML Models
Case Study: Robust Performance on Real-World Data
Our feature extraction tool was rigorously evaluated on the extensive MLORD dataset, comprising data from 17,327 patients, and also on real-time data from a Philips IntelliVue MX800 patient monitor. The tool consistently demonstrated exceptional reliability, accurately identifying landmarks and extracting features across diverse morphological variations in both ABP and PPG waveforms. This robust performance in varied scenarios underscores its readiness for practical clinical integration and advanced research applications.
The comprehensive set of 852 features extracted per cardiac cycle can be invaluable for training sophisticated machine learning models in various clinical applications. These include predicting hypotension or hypertension, identifying disease endotypes, estimating biological age, and predicting extubation failure. Integrating this tool into perioperative or critical care monitoring systems will significantly enhance clinical decision-making and facilitate timely interventions, ultimately leading to improved patient outcomes.
