Active clinical trials for "Lung Diseases, Obstructive"

This study is not being conducted in the United States. This study is designed to provide efficacy and safety data for formoterol 10µg twice-a-day (b.i.d.) delivered by the Certihaler in patients with chronic obstructive pulmonary disease (COPD). This study is also designed to compare the efficacy and safety of therapy with formoterol (Certihaler)10µg b.i.d. added to tiotropium (HandiHaler) 18µg once daily (o.d.) compared with tiotropium (HandiHaler) 18µg o.d. monotherapy, and to compare the safety and efficacy of formoterol 10µg b.i.d. (Certihaler) with tiotropium 18µg o.d. (HandiHaler).

This study evaluates the effect of cumulative dose administration of albuterol sulfate inhalation aerosol delivered with valved holding chamber and facemask. This is a four week study in birth to 23 month old subjects who are experiencing acute wheezing due to obstructive airways disease.

It will be randomized controlled trial. The research will be conducted at Bahawal Victoria hospital Bahawalpur and civil hospital Bahawalpur. We take 60 patients (Epitool), Patients will be allocated randomly in two groups. Group A will get conventional medical treatment and Group B will get both conventional medical treatment and pranayama breathing exercise. Both gender of age group 30 to 55, Patient with diagnosed Chronic obstructive pulmonary disease ,Moderate to severe Chronic obstructive pulmonary disease with productive cough, Shortness of breathe and no surgical procedure performed will be included in this study. And patients of lung surgery, lung cancer, above 70 years age, with open wound, cardiovascular issues, and neurological issues will be excluded. Yoga exercise pranayama, 6 min walk test, IPAQ- quality of life and VSAQ-exercise capacity will be used as tools. Data will be analyzed on SPSS 21.

This trial will test a COPD prediction algorithm into a telehealth system from the previous Danish large-scale trial, TeleCare North (NCT01984840). The COPD prediction algorithm aims to support clinical decisions by predicting exacerbations in patients with COPD based on selected physiological parameters (blood pressure, oxygen saturation, and pulse). A prospective, parallel two-armed randomized controlled trial with approximately 200 COPD participants will be conducted.

A Phase IV study evaluating changes in oxygen consumption and cardiac function in Subjects with Chronic obstructive pulmonary disease (COPD) with resting hyperinflation after administration of Symbicort pMDI 160/4.5 μg.

The main oxygen therapy to the patients with acute exacerbation of Chronic obstructive pulmonary disease, who are mild to moderate respiratory insufficiency (arterial blood gas analysis showed pH = 7.35, PO2 < 60mmHg,PaCO2>45mmHg) or have achieved the traditional noninvasive ventilation support standard but can not tolerate or reject, was nasal catheter, venturi mask and other conventional oxygen therapy. All these inaccurate inhaled oxygen concentration methods with inadequate heating and humidifying lead to poor patient tolerance and adverse reactions such as airway secretions discharge disorders. The high flow nasal respiratory therapy (Nasal high flow, NHF) utilises higher gas flow rates than conventional low-flow oxygen systems. The devices used deliver heated and humidified oxygen at a flow of up to 60 litres per minute via nasal cannulas with low level continous positive airway pressure. This study is a prospective randomized study. AECOPD patients with no severe respiratory failure are treated with NHF and conventional oxygen therapy respectively. The target is that NHF can increase the comfort degree of patients,reduce the rate of endotracheal intubation, and shorten the time of hospitalization.

Thirty-two subjects diagnosed with COPD were enrolled, received each study treatment and completed the follow-up assessments. During each of the four study periods, subjects were admitted to the clinic on Day -1 and housed overnight until after the last spirometry measurement. Serial pulmonary function tests were performed and PK (pharmacokinetics) samples collected up to 25 hours. Subjects were discharged from the clinic on Day 2 after evaluations.

The purpose of this study is to determine wether the interface (facial or nasal mask) influences performance in patients with chronic obstructive pulmonary disease exercising with non-invasive ventilation.

The purpose of this study is to evaluate the dose-response relationship of different doses of CHF6001 and to identify the optimal dose (s) in terms of benefit/risk ratio for further development in the target patient population.

Background：Respiratory muscle weakness is observed in chronic obstructive pulmonary disease(COPD) patients and contributes to hypercapnia, dyspnoea, nocturnal oxygen desaturation and reduced walking distance.During exercise it has been shown that diaphragm work is increased in COPD and COPD patients use a larger proportion of the maximal inspiratory pressure (MIP) than healthy subjects. This pattern of breathing is closely related to the dyspnoea sensation during exercise and might potentially induce respiratory muscle fatigue. Inspiratory muscle training(IMT) increases inspiratory muscle strength and endurance, and decreases dyspnoea.But the mechanism of IMT still lack of research. Purpose：The experiment is aim to compare of the similarities and differences of transdiaphragmatic pressure by detecting the transdiaphragmatic pressure of COPD patients and healthy volunteers in different intensity of threshold load conditions. Thus investigate how inspiratory muscle training works or mechanism in lung rehabilitation programmes of COPD.And emerging the theoretical basis of inspiratory muscle training from respiratory physiological mechanism.
