Can airway shape predict sleep apnea severity?
NCT ID NCT05774522
First seen Aug 11, 2026 · Last updated Aug 12, 2026 · Updated 1 time
Summary
This study investigates the link between the physical structure of the upper airway and its tendency to collapse during sleep, which is a key factor in obstructive sleep apnea. Researchers will measure airway collapsibility using a special pressure device, and assess anatomy via ultrasound and acoustic pharyngometry in 100 adults suspected of having sleep apnea. The goal is to see if these measurements correlate with apnea severity and could serve as screening tools.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Measurement of pharyngeal critical closing pressure (pCrit) and acoustic pharyngometry
- What this could lead to
- If successful, this could lead to better screening tools for sleep apnea and a deeper understanding of why airway collapse occurs.
- What could go wrong
- This is an observational study, so it won't test a treatment. The findings may not apply to all sleep apnea patients, and the measurements may not perfectly predict severity.
