At present, the clinical judgment method for the extent of sputum accumulation is less researched. This is because the relationship between human tissues inside human body is mutually coupled, physiological parameters are various, and the sputum deposition degree has a coupling relationship with various parameters, such as respiratory mechanics parameters, respiratory sound, types of lung diseases, human body attributes (age, sex, physique) and the like.
However, no relevant research can clarify the specific relationship between them, which increases the difficulty in distinguishing the phlegm stagnation.
