Breathing study for children needing bronchoscopy
This study collects samples (like fluid from the lungs) during a planned bronchoscopy to look for new ways to understand and predict children's breathing problems. It might help if your child already needs this procedure for a medical reason.
WarsawAges Up to 17 years - NCT07829003Enrolling by invitation
Step test to measure fitness in healthy adults
This study tests a new step-based exercise test to see if it works as well as a standard bike test for measuring fitness and breathing. If you are a healthy adult, you might join to help validate this simpler test.
EdinburghAges 18–55 - NCT06919757Recruiting
Early Lung Health in Very Premature Infants
This study compares the early lung development of very premature babies who had growth problems in the womb to those who did not. The goal is to understand how growth in the womb affects lung health after birth.
RomaAges Any age - NCT05756894Recruiting
Stimulation therapy to improve breathing after spinal cord injury
This trial studies a neurostimulation approach to help breathing problems after a spinal cord injury. You may be able to join if you have a certain type and level of spinal cord injury and breathing weakness, and you can safely attend study visits with caregiver support.
Chicago, IllinoisAges 18–85 - NCT02924818Recruiting
Research study for adults with long-term breathing lung diseases
This study enrolls adults with chronic lung conditions like COPD, cystic fibrosis, bronchiectasis, or interstitial lung disease. It’s designed to learn more about these illnesses and to develop better ways to study or improve care.
ReimsAges 18 years+ - NCT06006884Recruiting
Understanding long-term lung effects after COVID-19
This study looks at why some people develop long-term lung problems after COVID-19. It compares people who had severe COVID-19 and were hospitalized to those who had mild infections and recovered at home.
Rochester, MinnesotaAges 18 years+ - NCT06286085Recruiting
Comparing asthma tests in Portsmouth
This study looks at different ways to test for asthma. It uses data from patients who have already been evaluated at the Portsmouth asthma service, to see which tests work best for diagnosing asthma.
PortsmouthAges 18 years+ - NCT07516184Recruiting
Testing a breathing device to diagnose asthma
This study tests a portable handheld device that measures airway function to help diagnose asthma. Researchers want to see if this device can accurately identify asthma in people with breathing symptoms like wheezing and shortness of breath.
BeijingAges 18–75 - NCT06925295RecruitingPhase 2
Xenon MRI to guide radiation for lung cancer
This trial tests whether a special MRI that uses xenon gas can help doctors better plan radiation therapy for lung cancer. You may join if you are scheduled for stereotactic body radiation therapy for your lung cancer.
Iowa City, IowaAges 18–80 - NCT07051954Recruiting
Breathing muscle training for long COVID recovery
This study tests a special breathing and muscle training program to help people with long COVID feel better and move more easily. The training is designed to strengthen the muscles you use to breathe and to improve your daily function.
Ankara, ÇankayaAges 18–65 - NCT05391737Recruiting
Study of fluid in the lungs after open-water swimming
This study looks at what happens in the lungs after open-water swimming. It may help doctors better understand and recognize “swimming-induced lung fluid,” especially by using lung ultrasound when symptoms happen.
FalunAges 18 years+ - NCT07782099Recruiting
Breathing muscle function in chronic neck pain
This study compares breathing muscle function between people with chronic neck pain and healthy individuals. It aims to see if neck pain affects breathing muscles, which might lead to new treatments.
Kocaeli, DerinceAges 18–65 - NCT07595341Enrolling by invitation

Common questions
- Are there clinical trials for respiratory function tests?
- Yes. Clin2 currently lists 44 recruiting respiratory function tests 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 respiratory function tests 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 respiratory function tests 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.
