Comparison of Several Oxygenation Targets With Different Oxygen Interfaces - Impact on Oxygen Flow Rates

Oxygen therapy is at the heart of the healthcare system. Oxygen flow rates depend on a number of confounding factors confounding factors (target used, skin pigmentation, pulse oximeter used, etc.) The investigators have recently have recently demonstrated that the combination of these factors (different peripheral oxygen saturation (SpO2) targets and different oximeters) can have a significant impact on oxygen flows rates. The effect on oxygen flow was not simply additive . The aim of this study is to evaluate the impact of the interface used on oxygen flow rates in different patient populations (main objective). The investigatoers also evaluate the impact of the interface on carbon dioxide (PaCO2), in particular with closed oxygen masks, with which rebreathing is theoretically possible (secondary objective). secondary objective).

Effect of the Inhaled Triple Therapies Over the Small Airway in Biomass Exposure

This phase IV randomized controlled clinical trial intend to compare the effect of three close standard inhaled triple therapies and one close standard inhaled double therapy on the small airway in patients with Chronic Obstructive Pulmonary Disease (COPD-B) and chronic bronchitis without obstruction (BCNO) exposed to wood smoke. The treatment phase duration is of 3 months. As primary outcome, the resistance change in post-bronchodilatator impulse oscilometry will me measure at 30 minutes, 2 hours, 4 hours, and 24 hours post first dose of the asigned medication, and then at 1 and 3 months of treatment. As secondary outcomes, change in respiratory symptoms and health related quality of life will be assess after 1 and 3 months of treatment.

Effects of Blocking TSLP on Airway Inflammation and the Epithelial Immune-response to Exacerbation Triggers in Patients With COPD

A phase 2, multicentre, randomized, double-blind, placebo-controlled, parallel group study to evaluate the effect of tezepelumab on airway inflammation in patients with COPD.

Telehealth and Onsite Maintenance Exercise in Chronic Lung Disease

The goal of this pilot clinical trial is to compare telehealth and onsite supervised maintenance exercise program for adults with Chronic Lung Disease. The specific aims of the study are: * To compare 8-week supervised maintenance program delivered onsite and via tele-rehab with no maintenance for patients with Chronic Lung Disease following discharge from traditional exercise or physical therapy or onsite outpatient rehabilitation programs on clinical outcomes (dyspnea, exercise capacity, physical function, physical activity, and quality of life) at 8 weeks and 4-months post-intervention. * To compare the differences in dyspnea, exercise capacity, physical function, physical activity, and quality of life between an 8-week maintenance program delivered onsite and via tele-rehab at 8-weeks and 4-months post-intervention in patients with Chronic Lung Disease following discharge from traditional onsite outpatient rehabilitation. Participants in both intervention groups (onsite and tele-rehab) will undergo a baseline onsite assessment followed by an 8-week supervised exercise intervention either onsite or in a telehealth setting. Control group will receive biweekly check in calls, but no active intervention.
