title: [Diagnostic value of measuring resistance of airway in the bronchus diastole test for asthma].
abstract: OBJECTIVE
  To discuss the variation of resistance of airway (Raw) and the diagnostic value of the bronchus diastole test for asthma patient.
  
  
  METHODS
  The forced expiratory volume of the first second (FEV1) and Raw were measured.
  
  
  RESULTS
  1. The positive rate of FEV1 increase after the test was 68% (20/31). 2. There was a significant difference in percentage of FEV1 increase after the test between positive group and negative group. 3. After the bronchus diastole test, the Raw decreased significantly in both groups.
  
  
  CONCLUSIONS
  The decrease of Raw after bronchus diastole test is more valuable for the asthma diagnosis than that of FEV1.
