High Flow Nasal Cannula vs NPPV in Moderate Chronic Obstructive Pulmonary Disease Exacerbation

Recently, many clinical studies have showed that HFNC can be successfully used in patients with hypoxemic respiratory failure to improve the comfort, to attenuate respiratory failure and to decrease the rate of tracheal intubation and mortality. Although theoretically HFNC is a potential and ideal treatment for AECOPD patients, the related ...

Phase N/A

Effect of Oxymetazoline Hydrochloride in Combination With Fluticasone Propionate on the Apnea Hypopnea Index (AHI) in Subject With Persistent Nasal Congestion and Mild Obstructive Sleep Apnea

To evaluate the effectiveness of the addition of intranasal oxymetazoline to ongoing optimal doses of intranasal fluticasone propionate on the apnea/hypopnea index (AHI) in subjects with persistent nasal congestion and mild obstructive sleep apnea secondary to perennial allergic or non-allergic rhinitis despite treatment with the recommended doses of NGCS. The ...


HFNC vs Nasal Cannula in Mild Chronic Obstructive Pulmonary Disease Exacerbation

For AECOPD patients, most of patients don't need respiratory support, only 8% patients ventilated by noninvasive and invasive positive pressure ventilation. Nasal cannula is the most common pattern of oxygen therapy in mild AECOPD. As a low flow oxygen therapy, nasal cannula has many disadvantages: discomfort, low humidity and unstable ...

Phase N/A

High Flow Nasal Cannula and Hypercapnia

Fifthy COPD patients inpatients recovering from an acute exacerbation of their disease and persisting hypercapnia, despite having reached a stabilization in pH (i.e. pH>7,35 and PaCO2>45 mmHg on 3 consecutive measurements) will be enrolled in the study after having signed a written informed consent OSA/COPD overlap syndrome was not considered ...

Phase N/A

High Flow Nasal Oxygen Versus Usual Care in COPD Pulmonary Rehabiliation

This is a pilot randomized controlled trial to compare the effects of high flow nasal oxygen with usual care during an outpatient 6-week pulmonary rehabilitation program after hospitalization for COPD exacerbation.

Phase N/A

Sleep for Stroke Management and Recovery Trial

Sleep SMART has a prospective, randomized, open-label, blinded-endpoint (PROBE) design. It is a multi-site, parallel-group superiority trial that compares 6 months of OSA treatment to usual care. The study includes two trials: a prevention study with an embedded recovery trial. 3062 subjects will be randomized over 5 years at 110 ...

Phase N/A

Nasal High Flow to Maintain the Benefits of Pulmonary Rehabilitation in Chronic Obstructive Pulmonary Disease Patients

Experimental design: Patients achieving their last pulmonary rehabilitation session will be approached to participate in this study. Eligible patients who agree to participate in the study and sign informed consent will perform two baseline visit assessments: First visit: Incremental cardiopulmonary exercise testing. Second visit: Other baseline assessment (see outcome section), ...

Phase N/A

Nasal High Flow Therapy in Surgical Patients With Unrecognized Obstructive Sleep Apnea

The POSA-II trial is a culmination of the investigator's program of research to prevent postoperative adverse outcomes in surgical patients with untreated Obstructive Sleep Apnea (OSA). It is a multi center open label, randomized clinical trial of nasal high-flow vs. usual care in patients with untreated moderate-to-severe OSA undergoing major ...

Phase N/A

During-exercise Physiological Effects of Nasal High-flow in Patients With Chronic Obstructive Pulmonary Disease

Experimental design: Patients referred for pulmonary rehabilitation will be approached to participate in this study. Eligible patients who agree to participate in the study and sign informed consent will perform two constant workload exercise testing the same day with either nasal high-flow or sham nasal high-flow (separated by a 1 ...
