s3, acquiring a real-time breathing curve of the patient during breathing training, guiding the patient to complete breathing training according to the voice file, or according to the voice file and the real-time breathing curve of the patient during breathing training, or according to the voice file, the standard breathing curve and the real-time breathing curve of the patient during breathing training, and storing a training result curve;
and S4, comparing the training result curve with the standard breathing curve to determine and derive the optimal breathing training scheme.
