METHOD, APPARATUS AND DEVICE FOR PREDICTING WEANING FROM MECHANICAL VENTILATION, AND STORAGE MEDIUM

A method, apparatus and device for predicting weaning from mechanical ventilation, and a storage medium. The method comprises: acquiring a healthy vital sign portrait of a patient (S101); acquiring a ventilation parameter portrait corresponding to the patient when the patient can be weaned from mechanical ventilation (S102); acquiring a real-time vital sign portrait and a real-time ventilation parameter portrait of the patient during mechanical ventilation (S103); and determining a weaning decision-making result according to a first similarity between the healthy vital sign portrait and the real-time vital sign portrait and a second similarity between the ventilation parameter portrait and the real-time ventilation parameter portrait (S104). By means of the method, for each patient, the influence of a healthy vital sign portrait and a real-time vital sign portrait of the patient on a weaning decision-making result is fully taken into consideration, such that the time for weaning from mechanical ventilation fo
