Breathing muscle testing to help track lung disease
This study checks whether measurements of your breathing muscle (the diaphragm) can act as a useful “biomarker” to track lung disease. You might be asked to do breathing tests and follow study instructions, and your results may help researchers better monitor COPD, asthma, fibrosis, or pulmonary hypertension.
Aachen, North Rhine-WestphaliaAges 18 years+ - NCT07108920Recruiting

Breathing retraining for combat athletes
This study tests if a special breathing retraining program helps combat athletes who have trouble breathing properly during sport. It may improve how well you move and perform.
TainanAges 18–50 - NCT06823570Recruiting
Exercise and blood pressure medicine for better blood vessels
This study is testing whether a combination of blood pressure medication and a supervised exercise program can improve the health of your blood vessels. It's for people with mild to moderate high blood pressure who are not already on medication.
Düsseldorf, DüsseldorfAges 18 years+ - NCT07419555Recruiting
Belgian study on lung function over time
This study tracks lung function over time in people with chronic lung disease. It helps doctors understand how lung health changes and may improve future care.
EdegemAges 18 years+ - NCT07388173Recruiting
How respiratory infections affect daily life in older adults
This study looks at how acute respiratory infections (like the flu, COVID-19, or RSV) affect older adults' daily functioning. If you are 60+ and in the hospital with one of these viruses, your participation would help doctors understand the lasting impact on independence and health.
Rochester, New YorkAges 60 years+ - NCT07501923Recruiting
How heat exposure day and night affects human health
This study looks at how exposure to heat during the day, night, or both affects the health of healthy young adults. It may help understand how heat impacts the body and find ways to protect people from heat-related risks.
Hefei, AnhuiAges 18–30 - NCT06519474Recruiting
Elastic chest wrap for COPD breathing and walking
This study tests if wearing an elastic chest wrap during exercise can help people with COPD breathe better and walk farther. You would do breathing and walking tests with and without the wrap to see if it makes a difference.
HsinchuAges 20 years+ - NCT06627283Recruiting
Does breathing muscle training help tongue muscles?
This trial tests whether training the muscles you use to breathe can also improve your tongue muscle function. It looks for healthy adults between 18 and 65 who can follow instructions in French or Dutch.
LeuvenAges 18–65 - NCT02299921Recruiting
Alcohol and drug effects on immunity in ICU breathing patients
This study looks at how alcohol and other drugs can affect the body’s immune system in people who are very sick in the ICU due to breathing problems. It may help doctors better understand immune changes during critical illness and respiratory failure.
Aurora, ColoradoAges 18–90 - NCT07406295Recruiting
Breathing exercises to improve brain and immune health
This trial tests whether a daily breathing exercise device can improve blood flow to the brain and immune function in people with obesity. It may help reduce health risks linked to excess weight.
Tallahassee, FloridaAges 18–45 - NCT06477458Recruiting
AI analysis of CT scans for lung health before chest surgery
This study uses a computer program (deep learning) to analyze your chest CT scan and lung function test results before surgery. The goal is to see if the AI can help doctors better assess your lungs and plan your operation.
Guangzhou, GuangdongAges 18–75 - NCT07012135Recruiting
Autonomic Function in Multiple Sclerosis
This study looks at how the nervous system controls automatic body functions (like heart rate and blood pressure) in people with multiple sclerosis. Researchers want to compare results between people with MS and healthy volunteers to understand how MS affects these functions.
Rochester, MinnesotaAges 18–50 - NCT05427136Recruiting
Study early lung problems after childhood cancer treatment
This study looks for early lung (breathing) problems in children after certain cancer treatments, using lung tests and sometimes MRI scans. It may help doctors spot breathing complications earlier and guide better care.
BaselAges 4–22 - NCT07654439Recruiting
Mixed reality tests for overweight and obese adults
This trial tests if mixed reality (combining real and virtual worlds) performance tests are valid and reliable for overweight and obese adults. You may be able to help researchers improve these tests if you are overweight or obese.
Konya, SelcukluAges 18–65 - NCT06954636Recruiting
Smell test to predict glioblastoma outcomes (newly diagnosed)
This study looks at whether a simple smell test can help predict how glioblastoma will progress. It is for people who are newly diagnosed and have not started treatment yet.
EssenAges 18 years+ - NCT06923267Recruiting
Ultrasound to check heart function during breathing trials
This trial tests if using ultrasound to monitor your heart during a breathing test can help predict if you will need the breathing tube again. It is for people on a ventilator for at least 24 hours who are at higher risk of needing the tube reinserted.
OrléansAges 18 years+ - NCT06447831Recruiting
Home exercise tests for lung disease
This study tests how well people with chronic lung disease can do exercise tests at home, either with a researcher watching remotely or by themselves. The goal is to see if home-based tests are as reliable as clinic-based ones.
QuébecAges 40 years+ - NCT06069115Recruiting
How radiation affects lung function in breast cancer patients
This study looks at how radiation therapy for breast cancer may affect your lungs over time. Researchers will measure lung function and see if problems develop, so they can better understand and protect patients.

Common questions
- Are there clinical trials for respiratory function tests?
- Yes. Clin2 currently lists 47 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.
