Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

Patients with both sleep apnea and COPD have overlap syndrome, but their optimal management is not known. We plan to conduct a randomized trial of of bi-level PAP vs. night time oxygen to asses the impact of intervention on cardiac MRI and biomarkers.

Remote Health Monitoring (RHM) is the assessment of one's own symptoms at home between doctor visits, using things like at-home breathing tests, electronic diaries to answer questionnaires, and other monitoring devices. The hypothesis of this study is that the health and quality of life of people with COPD who do RHM for one year will be better than people with COPD who do not do RHM. Subjects who are at least 40 years old, have been diagnosed with chronic obstructive pulmonary disease (COPD), also known as chronic bronchitis or emphysema, and are current or former smokers will be invited to participate. This study is paid for by eResearch Technology (eRT). Subjects will complete 2 visits at UCLA, separated by one year of RHM. All subjects will participate in RHM. RHM will involve daily monitoring at home using a few electronic devices: blood oxygen levels, symptoms, medication use, breathing tests, and activity monitoring. Visits will include physical exam and medical history, ECG, questionnaires, breathing tests, and exercise tests.

This is a web-based randomized survey to evaluate management of respiratory symptoms among physicians in Sweden. The aim of this study is to determine if there is a gender bias in the diagnosis of COPD and how often physicians identify that chronic refractory breathlessness requires treatment as compared to refractory pain.

Chronic obstructive pulmonary disease (COPD) patients often undergo thoracic surgery due to lung cancer and emphysematous changes. One lung ventilation (OLV) used in thoracic surgery aggravates hypoxia and hypercapnia increasing intrapulmonary shunt and dead space.Ketamine provide bronchodilation by inhibiting the reuptake of catecholamines in the circulation. It also serves relaxation of bronchial smooth muscle. Our aim in this study, effects of ketamine on arterial oxygenation, the shunt fraction and the lung mechanics in patients with COPD who administered OLV because of thoracic surgery. Thirty patients with COPD who undergo thoracotomy for lung lobectomy will be included in this study. Patients will be randomly divided to a control group (%0,9 saline- CG) or a keta (ketamine- KG) group. KG will be administered 1 mg/kg ketamine bolus, then 0,5 mg/kg/hour ketamine infusion after the induction, CG will be administered sline bolus, then saline infusion. Peak airway pressure (Ppeak), plato airway pressure (Pplato), static compliance, shunt fraction, PaO2/FiO2 and arteriel blood gas values (Pa02, PaC02) will be recorded before initiation of OLV and 30 minutes intervals after initiation of OLV.To evaluate the postoperative pulmonary complications, Pa02, PaC02 in blood gas and Pa02/Fi02 values will be recorded 20 minute after arrival at postoperative care unit. Patients will be evaluated for pneumonia, atelectasis and acute lung injury at postoperative 72 h and findings will be recorded. 30 day mortality will be recorded.

Static hyperinflation is frequent in Chronic obstructive pulmonary disease (COPD) , resulting in increased end expiratory lung volume and positive end expiratory pressure (PEEPi) at the end of a normal expiration. Static hyperinflation worsens the work of breathing is increases patient's dyspnea. The application of a continuous positive airway pressure (CPAP) has been shown to improve static hyperinflation and to decrease the work of breathing. Sleep is deteriorated in COPD patients, and causal factors includes static hyperinflation. The purpose of our study is to assess the effect of nocturnal CPAP on sleep quality and functional respiratory parameters.

This trial will evaluate the effect of acetazolamide (375 mg per day) vs. placebo on right ventricular function at acute altitude exposure in patients with COPD.

In this trial, the investigators will evaluate the effect of acetazolamide (375 mg per day) vs. placebo on postural control at acute altitude exposure in patients with COPD.

It is not clear whether antibiotic therapy is needed in patients with mild to moderate exacerbation of chronic obstructive lung disease. The aim of the study is to compare the effect of 1 day of treatment with 6 days of treatment in patients who are admitted to hospital and being clinical stable (as judged by their physician) 24 hours after hospitalization

The primary objective of this study is to investigate the effect of 4-week treatment with 7.5 mg b.i.d, 15 mg q.d and 15 mg b.i.d. BIBW 2948 BS and placebo on cough and sputum as determined by the CASA-Q (Cough and Sputum Assessment Questionnaire

This study is intended to determine the safety and tolerance of regadenoson in subjects with asthma or chronic obstructive pulmonary disease.
