Abstract:
ObjectiveTo investigate the diagnostic value of mini peak flow meters in cough variant asthma (CVA). Methods131 patients with the main symptom of chronic cough whose chest X-ray showed normal were included in this study. The peak expiratory flow (PEF) rate of each patient was measured by mini peak flow meters during the bronchial dilation test, and the results were analyzed. ResultsThe rate of positive reaction in the test was 33.6% (44/131), of whom 40.9% (18/44) were delayed over 1 year. 16.8% (22/131) of all the patients' PEF increased 10% to 15% in after the test. ConclusionMini peak flow meters can be used in the diagnosis of CVA.
