Recruiting studies
- NCT07267546Recruiting
Study on heart-lung machine fluid and its effects in heart surgery

Using electrical impedance tomography for heart and lung imaging
This trial uses a safe, non-invasive technique called EIT to monitor heart and lung function in children and young adults with certain heart or lung conditions, compared with healthy volunteers. It may help doctors better understand and manage these conditions.
Aurora, ColoradoAges 2 weeks–25 years - NCT07193719RecruitingPhase 1/Phase 2
Personalized breathing support for kids after heart surgery
This study tests a personalized breathing technique to improve lung function and heart performance in children who have had heart surgery or are on ECMO. The goal is to find the best way to open up the lungs safely.
BerlinAges birth–18 years - NCT07144267Recruiting
Comparing two heart medications during surgery
This trial compares two medicines, milrinone and epinephrine, given during heart surgery to see which one better helps the right side of the heart work. It may help patients with weaker right heart function.
Al MansurahAges 18–70 - NCT07130968Enrolling by invitation
Heart and lung function study with exercise test and five-year follow-up
This study looks at how your heart and lungs work during exercise by using a special test called a cardiopulmonary exercise test (CPET). Researchers will follow you for up to five years to see how your health changes. It may help you understand your heart condition better and get more personalized care.
Guangzhou, GuangdongAges 18–80 - NCT06930443Recruiting
Oxygen use and organ injury after heart-lung bypass surgery
This trial looks at how oxygen is used during heart surgery that uses a heart-lung machine, and whether low oxygen levels can lead to organ damage. It may help doctors better understand how to protect patients during surgery.
Uppsala, SwedenAges 18 years+ - NCT07113769Recruiting
Biomarkers and platelets in CPR patients
This trial is studying the blood biomarkers and platelet characteristics in patients who receive CPR and are then placed on a heart-lung bypass machine (ECPR). It aims to understand how these biological markers relate to patient outcomes.
Zhengzhou, HenanAges 18 years+ - NCT06349577Recruiting
Bypass machine settings to protect kidneys during heart surgery
This study tests whether a special way of running the heart-lung bypass machine during planned heart surgery can help protect your kidneys and reduce the risk of kidney injury after the operation.
Aurora, ColoradoAges 18–85 - NCT07073612Recruiting
Fontan stent study for liver stiffness and exercise
This study looks at whether placing a stent in the Fontan blood vessel can improve liver health and exercise ability in teenagers and young adults. If you are between 12 and 21 years old and need a stent in your Fontan pathway, you may be able to join.
Los Angeles, CaliforniaAges 12–21 - NCT07064954RecruitingPhase 2/Phase 3
Using your own platelets for complex heart surgery recovery
This study tests whether using your own donated platelets during heart surgery can help you recover better. Platelets are cells that help your blood clot, and donating them before surgery may reduce the need for donor blood.
Toronto, OntarioAges 18 years+ - NCT07044154Recruiting
Sun Tai Chi for heart, lung, and mental health in college students
This trial tests whether a gentle Sun-style Tai Chi program can improve your heart and lung fitness as well as your mental well-being if you have mild to moderate stress, anxiety, or depression. It's for university students who are not already very active and who are not taking mental health medicines.
Talca, Maule RegionAges 18–29 - NCT07018856Recruiting
Can beginners detect collapsed lung after heart surgery via ultrasound?
This trial tests whether a beginner (like a nurse or trainee) can use an ultrasound to safely detect a collapsed lung (pneumothorax) after heart surgery when the chest tubes are removed. It could make care faster and safer for you.
Toronto, OntarioAges 18 years+ - NCT04183660Recruiting
MOBYBOX monitoring study for temporary heart-lung support
This is a post-market “real-world” monitoring study for a heart-lung machine (extracorporeal cardiopulmonary support/ECMO) used during very serious heart and/or lung failure. It aims to track safety and performance in patients who need rescue breathing or circulation support.
Hanover, Lower SaxonyAges 18–80 - NCT07009652Recruiting
Optimizing mobile ECMO for sudden cardiac arrest patients
This trial tests a better way to get a mobile team that can start ECMO (a heart-lung machine) to people who have a sudden cardiac arrest outside the hospital. The goal is to see if this approach can help save more lives in certain regions.
Ostrava, Moravian-Silesian RegionAges 3–60 - NCT07000461Recruiting
Doppler test to predict memory problems after heart surgery
This study uses a noninvasive ultrasound test (transcranial Doppler) before heart surgery to see if it can help predict thinking or memory problems that may occur after the operation.
IstanbulAges 18–70 - NCT06983899Recruiting
Exercise to boost immunity during lung cancer immunotherapy
This trial tests whether a supervised exercise program can help improve immune activity and treatment outcomes for people with non-small cell lung cancer who are already on immunotherapy. It is designed for people who are not currently very active.
Seattle, WashingtonAges 18 years+ - NCT06909773Recruiting
COPD testing in people with heart disease
This study looks for undiagnosed COPD in people with heart conditions like coronary heart disease, atrial fibrillation, or chronic heart failure. If you have heart disease and are over 40, you may join to see if you also have COPD and benefit from combined care.
AnqingAges 40 years+ - NCT06856525RecruitingPhase 2/Phase 3
MRI scan to study lung health in e-cigarette users
This study tests a new type of MRI scan to see how e-cigarettes affect your lungs. It's for young adults who vape nicotine regularly. The results may help doctors understand vaping-related lung damage.
Durham, North CarolinaAges 18–35 - NCT06809309Recruiting
Ventilation during in-hospital cardiac arrest study

BerlinAges 18–80 - NCT06776549Recruiting
Cooling or normal temperature after cardiac arrest with ECMO
This trial tests if cooling the body (hypothermia) or keeping normal body temperature (normothermia) after emergency heart-lung support (ECMO) improves survival in adults who had a cardiac arrest outside the hospital.
Kurume, FukuokaAges 18–75 - NCT06747546Enrolling by invitation

Common questions
- Are there clinical trials for cardiopulmonary?
- Yes. Clin2 currently lists 169 recruiting cardiopulmonary 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 cardiopulmonary 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 cardiopulmonary 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.
