Chronic Obstructive Pulmonary Disease (COPD) is a common smoking related lung disease. The main symptom in breathlessness.
Pulmonary Rehabilitation (PR) - a supervised group exercise and education class - is an effective intervention in COPD to reduce symptoms, improve exercise performance and prevent exacerbations. However some COPD patients are unable to to effectively exercise as they are limited by their breathlessness, despite optimal medical management. By reducing their physical activity to avoid the onset of breathlessness, they become deconditioned and then further attempts at exercise make them more breathless, leading to an inactivity cycle.
There is a growing evidence base regarding the use of hand hold fan therapy or air therapy to relieve breathlessness at rest. Limited studies have looked at the use of fan therapy during exercise, and its role on exercise capacity and recovery time, provisional results which indicate it may also be useful during activity. Logically you might expect patients who are less breathless to be able to exercise more, or recover quicker.
This study aims to investigate the effects a hand held fan will have on sensation of breathlessness and exercise capacity in patients with COPD. This will involve participants undertaking a standardised field walking test ( 6 minute walk test) with and with out the fan and then comparing the distance covered and how they felt during and after exercise. This will better inform how we structure exercise and advice to these patients in the future to empower patients limited by breathlessness.
