It belongs to the field of medical device and intelligent control technology. The method includes: collecting real-time physiological parameters of the patient and ventilator settings to generate an initial physiological dataset; performing individualized dynamic estimation of key physiological parameters based on the initial physiological dataset to obtain real-time estimates of the patient's physiological dead space ventilation and carbon dioxide production rate; providing precise initial settings and main control quantities through feedforward prediction, fundamentally reducing the occurrence of large deviations; and combining intelligent feedback fine-tuning to quickly smooth out small disturbances, achieving a combination of "coarse adjustment" and "fine adjustment," making the stability and accuracy of PaCO₂ within the target range far exceed that of single feedback control.

A method of identifying the occurrence of patient-ventilator asynchrony (PVA) includes using a cardiogenic index generated from a number of breath attribute signals measured by ventilators. The method can be implemented in a ventilator by a controller that includes a machine learning model trained to use the cardiogenic index and other features extracted from ventilator waveforms to identify the occurrence of PVAs. A ventilator equipped with such a controller can provide real-time alerts to a caregiver that a PVA has occurred so that the ventilator settings can be adjusted.

An embodiment includes use of a predictive model to ascertain a likelihood of a patient having expiratory flow limitation (EFL) to adjust the application of ventilator-based therapy. An embodiment may operate one or more predictive model on patient data alone to obtain a prediction of EFL for the patient, avoiding a need to perform invasive or ventilator based EFL detection, e.g., via a forced oscillation technique (FOT). An embodiment may be used in a system or method that adjusts ventilator settings for respiratory therapy, for example to abolish detected EFL in a patient having a positive classification for EFL.
