Filter by:Previous studies suggest that treadmill exercise may be a more relevant exercise stimulus than the cycle ergometer to demonstrate benefits with bronchodilator therapy in patients with COPD. The hypothesis of the study is that patients with COPD will exhibit greater improvements in exercise endurance and breathlessness with arformoterol compared with normal saline during treadmill walking than with cycle exercise.
Patients with Chronic Obstructive Pulmonary Disease (COPD) suffer from frequent and recurrent acute exacerbations (AECB) which are associated with enormous healthcare expenditures and significant morbidity, specifically an increased risk of death, a decline in pulmonary function and a significant change in quality of life. Bacteria appear to have an important role in acute exacerbations in chronic bronchitis and COPD. Studies of acute exacerbations in COPD have shown a reduction in bacterial load with prolonged exacerbation-free interval. In addition, recent studies indicate that acquisition of a new strain of H. influenzae, M. catarrhalis, S. pneumoniae or P. aeruginosa are responsible for many of these exacerbations. Chronic inflammation and bacterial infection predispose many patients to frequent and recurrent acute exacerbations. Mpex, (the sponsor on record at time of the study's initial registration) believes that intermittent administration of inhaled MP-376 in high risk patients will decrease the incidence of acute exacerbations by both by lowering the organism burden, and resultant inflammation, as well as pre-emptive eradication of any newly acquired bacterial strains.
The purpose of this study is to evaluate the safety, effectiveness, and side effects of the CryoSpray AblationTM System (CryoSpray AblationTM, "CSA" or "cryospray therapy") to treat benign airway disease in the lung using liquid nitrogen sprayed through a catheter via flexible fiber optic bronchoscopy (FFB)
Smoking causes both smoking related lung disease (COPD) and ischaemic heart disease. These are very common conditions and many patients have both diseases. Beta-blocker drugs are extensively used in the treatment of angina, high blood pressure and after heart attacks to decrease symptoms and prolong life. Beta-agonists are used in COPD to decrease breathlessness and improve exercise tolerance. It used to be thought that beta-blockers cannot be used in COPD patients as they may make the breathlessness worse, but it has now been established that they can be used safely. Beta-blocker drugs and beta-agonists have 'opposite' effects on the body and the investigators do not know if they can work together or if they would cancel each other out. The investigators also do not know which of the different types of beta-blockers now available are better for COPD patients. This study will investigate what happens to the airways of people taking both of these drugs.
The purpose of this study is to evaluate the use of Capnography (Continuous recording of the carbon dioxide content of expired air)as an alternative test to measure PC02 levels in patients with asthma, chronic obstructive pulmonary (COPD,interstitial lung disease(ILD)or coronary disease who are at risk of intubation.
The purpose of this study is to determine whether water based or land based group training is more effective for people with COPD.
The purpose of this study is to demonstrate equivalent efficacy between two different formulations of formoterol (pMDI using HFA-134 propellant and dry powder) on lung function in adult patients with partially reversible COPD.
From the relationship between pathophysiology of chronic obstructive pulmonary disease (COPD), dyspnea, and dynamic hyperinflation during ventilatory increasing, the investigators hypothesize that 1. Positive expiratory pressure (PEP) breathing will reduce dyspnea more than normal breathing during exercise in mild to moderate COPD patients. 2. PEP breathing will improve dynamic hyperinflation during exercise more than normal breathing in mild to moderate COPD patients. 3. PEP breathing will improve cardiorespiratory function during exercise than normal breathing in mild to moderate COPD patients.
The purpose of this study is to determine if Advair Diskus improves sleep quality by reducing lung hyperinflation in COPD.
This trial will test the hypothesis that the 6 minute walk test (6MWT) is not reproducible as a measure for oxygen desaturation.
