Abstract :

 Chronic obstructive pulmonary disease (COPD), a growing worldwide public health problem and is characterized by the gradual progression of irreversible airflow obstruction, increased inflammation in the airways and lung parenchymaObjective: Airway obstruction can be clinically quantified at the bedside by measuring the time taken for forced expiration (forced expiratory time). The aim of this study was to examine the accuracy of the forced expiratory time in detecting airflow limitation, and small airway disease when compared with gold standard test of airflow obstruction (spirometry). Method: Simple spirometry and forced expiratory time were performed on 100 subjects (age range; 50–84 years), referred to a pulmonary function laboratory at a tertiary care hospital. The diagnostic accuracy of forced expiratory time and its correlation with spirometric parameters were tested. Forced expiratory time ≥ 7 seconds was regarded as abnormal, and the ratio of forced expiratory volume in the first second to forced vital capacity of < 70% was considered indicative of an airflow limitation. Results: Forced expiratory time was found to correlate highly with spirometric parameters.. Conclusion: Forced expiratory time  correlate well with all parameters of a simple spirometry and can be used as a diagnostic test. it may be a helpful test to be used to support the diagnosis of small airway disease in periphery and smaller centres..
