Filter by:Hypothesis: The reduction of dynamic hyperinflation and its negative effects on the respiratory system following a bronchodilator could lead to an improvement of cardiac function in terms of increased cardiac output. This may enhance oxygen delivery to the exercising muscles in COPD patients. Bronchodilator administration may also have an indirect effect on V'O2 kinetics via its action on cardiovascular and pulmonary variables. Objectives: 1. To evaluate the effects of a bronchodilators on V'E , V'CO2 , and V'O2 kinetics in COPD during constant work-rate cycle exercise, and to evaluate whether bronchodilators will accelerate, indirectly, phase 2 kinetics (usually slower in COPD patients than normal subjects) and shorten t for V'E, V'CO2 , and V'O2 and shorten half-times for HR and O2 pulse, thus showing an improvement of oxygen transport to the peripheral active muscles. 2. To determine the impact of a bronchodilator-induced reduction in dynamic hyperinflation, and its effects on cardiovascular and pulmonary function, on exercise limitation in COPD.
The goal for COPD patients in pulmonary rehabilitation programs is to improve the quality of life. COPD is known to be worse at night as are other respiratory problems such as CHF. Saturation is known to get worse nocturnally as well. Furthermore, these COPD rehabilitation patients tend to be older and increasing age is associated with an increase in the incidence of sleep disorders. We suspect that there is an increase in the incidence of sleep disorders in COPD patients. We plan to further study these patients using questionnaires. A preliminary study was done, but the results were not comparable to national statistics. We plan to repeat the study, only changing the questions to a format comparable to data from the National Sleep Foundation.
This study is being conducted to see if PRX-08066 can lower pulmonary artery pressures in patients with pulmonary hypertension associated with chronic obstructive pulmonary disease.
This clinical study is designed to explore dose ranging and identify methods to demonstrate the efficacy of Erdosteine in patients with stable Chronic Bronchitis associated with Chronic Obstructive Pulmonary Disease.
Some patients with chronic obstructive pulmonary disease (COPD) take nebulised treatments to ease the symptom of breathlessness, including the drug ipratropium. Nebulised bronchodilator drugs are taken up to 4 times through the day, and this can take up to 15 minutes each time. Although the treatment isbe effective, patients report that the time taken to set-up and use the nebuliser can be a disincentive to regular use. By contrast, an inhaler device is easy to use following appropriate instruction, and takes only a few seconds to administer. Inhaled tiotropium is a once daily treatment taken by inhaler which has been shown to be effective in COPD. We wish to assess whether inhaled Tiotropium as effective as nebulised ipratropium in patients with stable chronic obstructive pulmonary disease.
Non-invasive ventilation has become increasingly important in the management of patients with acute respiratory failure. One of its major goals is to prevent the need for invasive ventilation, which is associated with numerous complications. This study compares the usefulness and safety of two noninvasive techniques which are used in Medical practice: Noninvasive positive pressure ventilation using a face mask and extrathoracic biphasic ventilation using a cuirass. Each of these techniques has advantages and disadvantages and both may not suit all patients. It is therefore important to compare the two in terms of effectiveness in preventing invasive ventilation and their side effects profile, so that we can improve our understanding and expertise in the treatment of patients in respiratory failure.
Aims of the study - to evaluate the rate of enteric gram negative bacteria colonization in tracheotomised COPD patients - to evaluate the effect of azithromycin long-term treatment on Pseudomonas aeruginosa colonization and colony counts, and on reduction of the number of exacerbations/hospitalisations, antibiotic courses and steroid use. - to evaluate the Quality of Life of patients treated and not treated with azithromycin, using a validate Italian version of St George questionnaire - to evaluate the rate of chronic colonization with atypical pathogens - to evaluate the safety and tolerability of a long-term treatment with azithromycin, including a survey on possible bacterial antibiotic resistance pattern variations
Pulmonary rehabilitation of COPD patients are implemented in a non-randomized manner in two settings: primary and secondary health care. The effect on quality of life and hospitalizations will be evaluated
Patients admitted to the hospital with chronic obstructive pulmonary disease are evaluated with regard to early follow-up by a specialized nurse in the home after discharge.
The purpose of this study is to determine if ramelteon has respiratory depressant effects in subjects with moderate to severe chronic obstructive pulmonary disease.
