Breathing and blood-flow testing in long-COVID symptoms
Part of Infections, Lungs & breathing clinical trials.
This trial studies how the lungs’ breathing (airflow) and blood flow may be off in people with long-COVID symptoms like tiredness, shortness of breath, or trouble exercising. It may help researchers understand what’s driving symptoms and what kinds of abnormalities could be targeted.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are at least 18 years old
- You had a COVID-19 infection more than 3 months ago (or you are in the control group with no prior COVID-19)
- If you’re in the long-COVID group: you have new or worsening chronic fatigue, shortness of breath, or exercise intolerance since COVID-19 and the cause isn’t clear
- Your initial lung test (pulmonary function tests) is normal or only mildly abnormal
- You have no COVID-19 infection in the last 3 months and no breathing infection in the last 4 weeks
- You can consent and speak English; you are not pregnant

This trial tests whether a spa treatment (using water therapy and relaxation) can help people with long-term symptoms after COVID-19, like fatigue or shortness of breath. It is designed for people who were not hospitalized and whose symptoms have lasted for several months.
This study uses breathing exercises from yoga and MRI (a scan of the body) measurements to see how well yoga breathing can improve ongoing breathing symptoms after COVID-19. It also compares results in a few other specific groups and healthy volunteers.
This study uses special PET/CT scans to look at what is happening in your body after COVID-19, to better understand and personalize treatment for ongoing symptoms like fatigue and breathlessness. If you qualify, you'll get advanced imaging that may help your doctors tailor your care.
This study looks at people with lingering post-COVID symptoms, especially breathing and lung-related findings, using home monitoring and medical tests. It may help researchers understand what’s driving ongoing symptoms and identify patterns that could guide better care.
This trial tests a program to help people with ongoing fatigue, shortness of breath, or chest pain after COVID-19. It uses a personalized plan to improve your daily function and heart health.
This study tests whether a structured breathing control technique can improve symptoms of long COVID. It may help by training how you breathe, but you must meet specific health and medication criteria to join.
