Common chronic bronchitis inspection

Common chronic bronchitis inspection1, X-ray inspection
Early can not unusual. Recurrent lesions caused bronchial wall thickening, small or bronchial alveolar interstitial infiltration of inflammatory cells or fibrosis, that the two Fei Wenli thickening, disorder, or a mesh of the cable-like, dot-like shadow of the lung field more obvious .

Second, respiratory function tests
Early often not unusual. For small airway obstruction, the peak expiratory flow rate - volume curve at 75 percent and 50 percent lung capacity, the flow decreased significantly, compared to the first second forced expiratory volume is more sensitive; closed volume increase. To the development of airway obstruction or stenosis, there is obstructive pulmonary ventilation function of performance, such as the first second forced expiratory accounts to reduce the ratio of forced vital capacity (<70%), the largest decrease ventilation (
Third, blood test
Acute or chronic bronchitis complicated by lung infection, white blood cell count and that neutrophil increase. Asthmatic who eosinophils may be more habitat. No change in remission and more.

4, sputum examination
Smear or culture that streptococcus pneumoniae, Haemophilus influenzae, Streptococcus A, and so on and Neisseria. The Pap smear shows that a large number of neutrophil, the goblet cells have been destroyed, asthmatic, the more common eosinophil.

According to cough, sputum or with breathing, the annual incidence continued for three months, for two consecutive years or more, and rule out other heart and lung diseases (such as tuberculosis, pneumoconiosis, asthma, bronchiectasis, lung cancer, heart disease, heart failure, etc.), To make a diagnosis. If the annual incidence continued to less than three months, and have a clear objective examination based on (such as X-ray, respiratory function, etc.) can also be diagnosed.
