Assessing breathing patterns during non-invasive ventilation

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates the effectiveness of different masks used in non-invasive ventilation (NIV) for patients with Chronic Obstructive Pulmonary Disease (COPD) and Obesity Hypoventilation Syndrome (OHS). Participants will undergo a series of breathing assessments while using two different NIV masks to determine which provides better comfort and breathing support. The study involves both awake and overnight assessments to gather comprehensive data on breathing patterns and mask efficacy. The goal is to improve long-term NIV management and patient outcomes.
