Background:
Bronchiolitis is a heterogeneous group of disorders, each with its own clinical and radiographic presentation, treatment options, and prognosis. Until now, classifications were based on pathology and radiology.
Summary:
Bronchioles are smaller than 2 mm in diameter and do not contain cartilage and mucous glands in their walls. Bronchiolitis is the term used to designate a disorder of the bronchioles and can have multiple etiologies. A specific diagnosis requires an extensive anamnesis, physical examination, pulmonary function testing, radiographic studies, and pathological investigation. We made a classification of bronchiolitis based on etiology, in order to give a diagnostic and therapeutic guidance. Further investigation is needed to optimize treatment for specific types of bronchiolitis.
Key Messages:
In this paper, a classification of bronchiolitis based on etiology is made. The paper provides in the diagnostic and therapeutic approach, although further investigation is needed to optimize treatment for specific types of bronchiolitis.

Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
