Chronic obstructive pulmonary disease (COPD), is a lung disease characterised by chronic obstruction of lung airflow that interferes with normal breathing and is not fully reversible. COPD causes coughing that produce large amounts of mucus, wheezing, shortness of breath, chest tightness, and other symptoms. 1 Secretions produced in the respiratory tract are cleared by mucociliary transport, cephalad airflow bias, and cough. There is need to find an alternate cost effective, easy technique for secretion removal. 4 An intervention like huff training could help better in clearance of airways. Clinically it is observed that its is difficult for persons with airflow obstruction to do the act of Huff to clear the secretions. So there is need to device an instrument which will facilitate the huff technique & is inexpensive. The therapistmade huffing device made from the PVC pipe & perforated balloon will help loosening and removal of secretions as the perforated balloon tied at the other end of pipe will act as a visual feedback & also a mild resistance against active exhalation. Forced expiration against resistance has demonstrated better sputum production. Procedure: Institutional ethical commiteepermision was taken before starting the study.Two groups were made, group A(Experimental group) and group B(Control group) comprising of 10 subjects each. All the subjects were explained about the study and a informed written consent was taken from them. Subjects were randomly allocated. Group A was given Huff through the therapist made huffing device whereas group B was given conventional Huff & 24 hours sputum expectoration was collected in the calliberated sputum mug & it was measured at the end of 24 hours . Results:Amount of sputum was statistically analysed using Mann Whitney’s Test. Conclusion: The study concludes that HUFF given through the therapist made device was more effective than the traditional HUFF in clearance of airway secretions in subjects with Acute Exacerbation of Chronic Obstructive Pulmonary Disease.
