Use of Patient Vital Sign Data for Preventing Medical Errors

Invention Summary

Medical errors are often due to patient misidentification. This technology leverages an artificial intelligence (AI)-based system that utilizes patient vital sign data to prevent misidentification. The system uses a gradient descent expert system (GDES) network to analyze vital signs such as heart rate, end-tidal carbon dioxide, respiratory rate, and blood pressure. By comparing current and historical vital sign data, the system identifies potential misidentifications, alerting healthcare providers to discrepancies.
