Abstract:
Objective To explore the significance of negative expiratory pressure technique in detecting expiratory flow limitation in chronic obstructive pulmonary disease (COPD) patients. Methods Negative expiratory pressure technique was performed in 13 special COPD patients who did not accomplish routine pulmonary function tests. Results Negative expiratory pressure technique was executed successfully in 13 special COPD patients without any side-effects. Expiratory flow limitation was detected in 12 special COPD patients. 5-point expiratory flow limitation score was significantly correlated with Medical Research Council (MRC) dyspnea score, which was a predictor of dyspnea. Conclusions Negative expiratory pressure technique provides a test which is simple, rapid, noninvasive and does not require any initiative cooperation from the patients, it can be applied in special COPD patients who can not accomplish routine pulmonary function tests.
