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 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 looks at how well hypoglossal nerve stimulation (a device that helps keep your airway open during sleep) works by measuring how collapsible your airway is during a special sleep endoscopy. If you already use this therapy, participating may help doctors understand why it helps some people more than others.
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.
This trial tests a device that sends mild electrical pulses through the skin to help keep your airway open while you sleep. It may be an option if you have tried CPAP but found it too difficult to use regularly.
This trial tests a new nerve-stimulation therapy called Neuromod to treat moderate-to-severe sleep apnea in people who do not have access to other treatments. If you qualify, you would be part of a study to see if this implant helps improve your breathing during sleep.
