![]() Severe cases can require hospitalisation. Patients are prone to exacerbations characterised by periods of acute worsening of symptoms such as dyspnoea, cough, airway inflammation, and excess sputum production (hypersecretion). COPD is the fourth largest cause of death. This response is caused by prolonged exposure to noxious particles or gasses, most commonly cigarette smoke, occupational dusts (from stone cutting, mining, metal grinding etc.) or other environmental dusts (e.g., woodworking). Data on user experience of the device were also collected during post-study follow-up.Ĭhronic obstructive pulmonary disease (COPD) is characterised by non-reversible airflow limitation due to an abnormal inflammatory response in the lungs. The aim of the current study was to initially evaluate the safety of the prototype in patients with COPD over a period of 1 month to ensure no adverse events, negative impacts on lung function, exercise tolerance, or quality of life. ![]() The device was previously evaluated successfully in a group of paediatric CF patients. Adherence to cleaning regimens for respiratory devices is often poor and in response to this, a prototype disposable OPEP device-the ‘UL-OPEP’ (University of Limerick-Oscillating Positive Expiratory Pressure device)-was developed to mitigate the risk of contamination by pathogens. Current devices are reusable and require regular cleaning and disinfection to prevent harbouring potentially pathogenic organisms. Handheld oscillating positive expiratory pressure (OPEP) devices have been a mainstay of treatment for patients with hypersecretory conditions such as cystic fibrosis (CF) and chronic obstructive pulmonary disease (COPD) since the 1970s.

Conclusion: The present study concluded that both autogenic drainage and flutter are equally effective in improving PEFR, SpO2 and FEV1 but flutter is more effective in improving FEV1 and easier for the patient to learn and less time consuming than autogenic drainage.Open AccessThis article is licensed under a Creative Commons Attribution 4.0 International License, which permits use, sharing, adaptation, distribution and reproduction in any medium or format, as long as you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons licence, and indicate if changes were made. Result: Both the techniques were effective in improving PEFR, SpO2 and FEV1 but flutter was more effective in improving FEV1. Treatment was given once daily for 5 days. Method: Forty-four patients having moderate to severe COPD participated of which 22 were given autogenic drainage and 22 were given flutter and its effect was seen on PEFR, SpO2 and FEV1. ![]() Aim: To compare the effect of Autogenic Drainage and Flutter device on PEFR, SpO2 and FEV1 in moderate to severe COPD patients. Flutter and autogenic drainage can be self administered by the patients and are easy to learn. ![]() Bronchial hygiene techniques like Postural drainage, ACBT, manual hyperinflation, flutter, acapella and autogenic drainage are used to remove secretions. Hypersecretion in COPD leads to obstruction in airways. Chronic obstructive pulmonary disease is a common, preventable, treatable disease that is characterized by persistent respiratory symptoms and airflow limitations that is due to airways and/or alveolar abnormalities usually caused by significant exposure to noxious particles /gases.
