Evaluating upper airway collapsibility and muscle responsiveness in sleep apnea patients

Official title: Diurnal Evaluation of Obstructive Sleep Apnea (OSA) Upper Airway Collapsibility and Muscle Responsiveness

Run by Istituto Auxologico Italiano · NCT06334601 · Data updated 2026-11-12

This study is trying to see how well the upper airway holds up and how responsive the muscles are in people with obstructive sleep apnea while they are awake, to help improve future treatments.

Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are individuals diagnosed with moderate to severe obstructive sleep apnea as indicated by their apnea-hypopnea index.

Probably not a fit

Patients currently undergoing treatment for OSA or those with unstable cardio-respiratory diseases may not benefit from this study.

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

What this trial studies

This observational study aims to assess the collapsibility of the upper airway and the responsiveness of muscles in patients with obstructive sleep apnea (OSA) during wakefulness. It utilizes a simplified method to measure these traits, which could enhance understanding of the pathophysiology of OSA. Participants will undergo tests to evaluate their upper airway characteristics based on specific inclusion criteria related to their sleep apnea severity. The study is designed to gather data that may inform future treatment strategies for OSA.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnostic methods and treatment approaches for patients with obstructive sleep apnea.

How similar studies have gone: While this approach is focused on a specific aspect of OSA, similar studies have shown promise in understanding airway dynamics, suggesting potential for success.
