PROCEDURES AND DEVICE FOR IDENTIFYING THE QUALITY OF MECHANICAL PATIENT-FAN INTERACTION BASED ON RECURRENCE QUANTIFICATION ANALYSIS OR RECURRENCE CHARTS

摘要

processes and device for identifying the quality of mechanical patient-ventilator interaction based on recurrence quantification analysis or recurrence graphs. The present patent application describes methods and a device capable of identifying the quality of mechanical patient-ventilator (pvi) interaction based on recurrence quantification analysis (aqr) and recurrence graphs (gr). The proposed technology uses the signal representing the respiratory flow provided in mechanical ventilation equipment to form a time series of the respiratory flow containing the data necessary for the application of the grs and aqr techniques, which includes recurrence rate and entropy calculations. shannon, resulting in a process that makes it possible to identify pvi quality and monitor mechanical ventilation performance. technology identifies pvi quality by associating it with predefined clinical scenarios. The advance provided by technology is to identify the quality of pvi without the need for invasive techniques quickly and easily due to the data compression provided by the technique used (aqr / gr). The technology applies in the context of invasive mechanical ventilation in intensive care units and centers and in the medical-hospital equipment industry.
