Artis Tajir Nakal Etiology: There are three types of causes of acute bronchitis, namely: (a). Infection: Staphylococcus (Staphylococcal), Streptococcus (strep), Pneumococcus (pneumonia), Haemophilus influenzae. (b). Allergies (c). Environmental stimuli, eg, factory smoke, car exhaust, cigarette smoke, etc.. Chronic bronchitis can be a complication of pathological abnormalities in several organs, namely:
(1). Chronic heart disease, caused by pathological abnormalities in the valves or miokardia. Chronic congestion in the bronchi walls weaken resistance to bacterial infection easily occur. (2). Paranasalis sinus infection and oral cavity, the area is a Cumber bacterial infection that can attack the walls of bronchi. (3). Dilatation of bronchi (bronkInektasi), causing disruption bronchi wall structure and function so that the bacterial infection easily occur. (4). Cigarettes can cause paralysis of the mucous membrane of bronchi feathers vibrate so that the drainage of mucus disturbed. Collection of mucus is a good medium for bacterial growth.
Pathophysiology: The attack of acute bronchitis may arise in a single attack or may arise again as an acute exacerbation of chronic bronchitis. In general, the virus is the beginning of an attack of acute bronchitis in the upper respiratory tract infection. The doctor will diagnose chronic bronchitis if the patient has a cough or sputum production experience for more than three months within a year or at least in two consecutive years. The attack of bronchitis caused by the body exposed to infection and non-infectious agents (particularly cigarettes). Irritants (substances that cause irritation) will cause an inflammatory response which causes vasodilation, congestion, mucosal edema, and bronchospasm. Unlike emphysema, bronchitis affects more small and large airway than alveoli. In case of bronchitis, the air flow is still possible not obstacle.
