Recruiting studies
- NCT05527652Recruiting
Breathing tube device to help blocked upper airways in children
This study tests a self-supporting breathing tube placed through the nose during sleep to reduce upper airway blockage and improve breathing in children. It may help children who have sleep apnea symptoms, especially after tonsil/adenoid treatment or when tonsil removal isn’t possible.
Ann Arbor, MichiganAges 3–21 - NCT06436638Recruiting
CPAP mask vs. nasal tube for breathing during molar extraction
This trial compares two ways to help you breathe during deep sedation for a molar extraction: a CPAP mask over your nose or a small tube placed in your nostril. The goal is to see which method keeps your oxygen levels more stable.
KayseriAges 18–60 - NCT05974488Recruiting
Using a throat airway to help oxygen during TEE
This study tests whether placing a specific airway device in the lower throat can improve oxygen levels while you get a TEE (a heart ultrasound done through the throat). It may help make the procedure safer and more comfortable for some people, compared with standard care.
Miami, FloridaAges 18 years+ - NCT06614582Enrolling by invitation
Long-term nose tube study for children with weak muscle tone
This study looks at the long-term safety and effectiveness of a nose tube (nasopharyngeal airway) for children who have obstructive sleep apnea due to weak muscle tone. It's for children who already used this device in a previous study.
Ann Arbor, MichiganAges 3–23 - NCT05494346Recruiting
Seawater nasal spray with essential oils for blocked nose
This trial tests whether a seawater nasal spray (with essential oils) is safe and works well for people ages 12+ who have sudden (acute) cold- or allergy-related nasal blockage. You may be able to join if you can use the spray as instructed and complete simple monitoring and questionnaires.
Blainville-sur-OrneAges 12 years+ - NCT04190953Recruiting
Braces and expanders in kids to improve airflow space
This study looks at how jaw and palate treatments affect airflow through the upper airway in children with a specific bite and jaw shape. It may help researchers understand which treatments improve space for breathing and related pressure changes.
Edmonton, AlbertaAges 8–14 - NCT06677151Recruiting
New sleep apnea device study for CPAP users
This study tests a new device for sleep apnea that you can use instead of a CPAP machine. If you have moderate to severe sleep apnea and CPAP isn't working well for you, this study may help find an easier option.
Ann Arbor, MichiganAges 18 years+ - NCT06570629Recruiting
Fixing air leaks with nasal CPAP
This trial looks at ways to fix air leaks that happen when using a CPAP mask at night. It may help if you have sleep apnea and your CPAP is leaking a lot despite using a nasal mask.
São Paulo, BrazilAges 18 years+ - NCT06570616Recruiting
Reducing mask leaks during CPAP for sleep apnea
This study tests a method to help CPAP users with nasal masks who have high air leaks. It aims to find better ways to reduce unintentional leaking so treatment works more effectively.
São Paulo, BrazilAges 18 years+ - NCT03725956Recruiting
Sleep study before and after nasal polyp surgery
This study uses a sleep test to look at breathing and sleep patterns in people with nasal polyps who need surgery because medicine didn’t help. It may help doctors understand how nasal polyps affect sleep and how surgery changes those sleep measurements.
LilleAges 18 years+ - NCT06795971Recruiting
Comparing oxygen methods for hypoxemic respiratory failure
This trial compares three ways of giving extra oxygen to people with low blood oxygen levels: a face mask with continuous pressure, a noninvasive ventilator, or high-flow oxygen through the nose. The goal is to see which method helps people avoid needing a breathing tube.
Nanjing, JiangsuAges 18 years+ - NCT06884592Recruiting
Predicting difficult breathing tube placement in septoplasty surgery
This study looks at factors that may predict difficult intubation (placing a breathing tube) in people having septoplasty surgery. It aims to find out how common this is and what signs might help doctors prepare better.
Başakşehir, IstanbulAges 18–65 - NCT07384494Recruiting
High-flow oxygen vs regular oxygen for awake intubation with difficult airways
This trial compares two ways of giving oxygen during a procedure where you are awake but have a tube placed in your windpipe. It may help patients with airways that are hard to open safely.
Wuwei, GansuAges 18 years+ - NCT06081647Recruiting
Testing a new airway device for endoscopy
This trial tests a special mouth-and-throat device designed to help you breathe easier during a routine endoscopy or colonoscopy. If you are a generally healthy adult scheduled for one of these procedures, you may be able to join.
Nanjing, JiangsuAges 18–60 - NCT07484841Recruiting
Comparing ways to insert a breathing tube while awake
This study compares different methods for placing a breathing tube while you are awake. It is for people who are having planned surgery and might have a difficult airway—for example, if doctors expect challenges with a face mask, a breathing tube, or if you have a short time before you stop breathing.
İzmit, KocaeliAges 18 years+ - NCT06796764Recruiting
Breathing tube safety during endoscopy in people with obesity
This trial tests a special breathing tube to see if it can prevent low oxygen levels during sedated endoscopy in people with obesity. If you are scheduled for both an upper endoscopy and colonoscopy, this study may help make the procedure safer.
Hangzhou, ZhejiangAges 18–70 - NCT06966934Recruiting
Nasal airway and oxygen for stomach scope in obesity
This trial tests whether a breathing tube placed in the nose (nasopharyngeal airway) combined with high-flow oxygen can improve safety during painless gastroscopy in people with obesity. It may help you breathe better while sedated.
NanjingAges 18 years+ - NCT07175155Recruiting
Breathing device and oxygen for endoscopy in severe obesity
This study tests a special breathing device (a tube placed in the throat) combined with high-flow oxygen through the nose during sedation for endoscopy in people with severe obesity. It aims to see if this combination helps keep oxygen levels stable and makes the procedure safer.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06694311Recruiting
Testing CPAP and high-flow oxygen for ARDS
This study tests two types of breathing support—CPAP (a mask that pushes air into your lungs) and high-flow nasal oxygen (a special tube in your nose)—to see which works better for people with ARDS, a serious lung condition. It may help you breathe more easily without needing a breathing tube.
Barcelona, BarcelonaAges 18–80 - NCT06781593Recruiting
Light therapy and CPAP for depression with sleep apnea
This study tests if adding bright light therapy to standard CPAP treatment helps improve mood in people who have both depression and sleep apnea. You may benefit if your depression and sleep apnea are both being treated.
Bron, FranceAges 18 years+ - NCT07254026Recruiting
Precision health and smart telerehabilitation for sleep apnea
This trial tests a smart home-based program using telerehabilitation to help people with obstructive sleep apnea. It aims to see if personalized health coaching and remote exercise can improve sleep and overall health.
TainanAges 20 years+ - NCT02703207Recruiting
Sleep apnea and COPD effects in older veterans
This study looks at how sleep apnea affects thinking skills and overall health in older veterans who also have COPD. It may help researchers understand what changes to target to improve daytime functioning and wellbeing.
Detroit, MichiganAges 60–89 - NCT07056075Recruiting
Preventing oxygen drops during ERCP
This trial tests two ways to prevent drops in oxygen levels during ERCP: one uses a special face mask to keep your airway open, and the other monitors your exhaled carbon dioxide. If you qualify, it could help make your procedure safer.

Common questions
- Are there clinical trials for nasal airway obstruction?
- Yes. Clin2 currently lists 27 recruiting nasal airway obstruction studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a nasal airway obstruction trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a nasal airway obstruction trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
