Testing how lung air volume affects airway narrowing during sleep testing
Part of Brain & nervous system, Lungs & breathing clinical trials.
This study looks at whether changing lung air volume affects how open or blocked your upper airway is during a drug-induced sleep test (DISE). It may help guide surgical choices for people with obstructive sleep apnea (OSA).
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are an adult (18 years or older).
- You have obstructive sleep apnea with at least 5 breathing events per hour (AHI ≥ 5).
- You are willing to consent to the DISE procedure as part of your usual sleep evaluation, and anesthesia has cleared you.
- You do not have serious, uncontrolled health problems that make anesthesia or surgery unsafe (for example, unstable heart disease or not well-controlled heart failure/COPD).
- You can tolerate the test equipment, including a negative-pressure ventilator, and you can do breathing testing (PFT); severe claustrophobia may exclude you.
- No disability that would prevent you from completing the study steps.

This study looks at how breathing passages narrow during sleep to better understand obstruction patterns. It may help people who are being considered for alternatives to CPAP (a common breathing device) for sleep-disordered breathing.
This trial studies whether muscle stimulation during DISE (a procedure to look at your airway while you’re sedated) can help people with obstructive sleep apnea who can’t tolerate CPAP. Your DISE is part of routine care, and the study adds a muscle stimulation step to see if it changes what’s happening in the throat.
This study tests different positive airway pressure (PAP) machines for people with obstructive sleep apnea (OSA) who have been on treatment for at least 3 months. You would try each system for up to 7 nights to see how they work for you.
This study tests a new proactive therapy for people recently diagnosed with moderate or severe sleep apnea. It aims to see how well patients stick with the treatment outside of a sleep lab.
This Phase 2 study looks at the cardiovascular (heart/blood vessel) effects of having both sleep apnea and COPD. It may help doctors better understand who is at risk and how to manage these breathing problems together.
This study collects information from adults who are getting a sleep test because obstructive sleep apnea is suspected. It helps researchers better understand sleep apnea and who develops it, without giving a new treatment.
