Lower respiratory infections such as COPD and pneumonia are the main cause of death worldwide. Despite such importance, there is relatively low awareness of the importance of management compared to chronic diseases such as obesity and diabetes.
Primary screening for respiratory infections is checking pulmonary sounds through the stethoscope.
Since it is conducted by visiting a hospital, it is ineffective for diseases with low hospital visit rate.
Since analog stethoscopes are mostly used, data are deleted immediately upon auscultation.
If there is no symptom at the time of auscultation, it is difficult to check and dependent on subjective judgments of the medical team.
