Finding the best temperature during heart-lung machine surgery
This study looks at the best body temperature to use during heart surgery when a heart-lung machine is needed. You may be able to join if you are having bypass surgery or valve repair, your risk score is moderate or higher, and your surgery is not an emergency.
Leicester, LeicestershireAges 18 years+ - NCT06702553RecruitingPhase 3
Nitric oxide to reduce support after heart surgery
This trial tests whether giving nitric oxide gas during heart surgery can help patients recover faster and need less breathing and circulation support afterward. It is for people having planned heart or aortic surgery with a heart-lung machine for the first time.
Boston, MassachusettsAges 18 years+ - NCT05740397Recruiting
Testing blood pressure targets during heart-lung bypass
This trial compares different strategies for keeping a specific blood pressure level during heart-lung bypass surgery. It may help reduce complications by finding the safest blood pressure target during the operation.
VeronaAges 18–80 - NCT06013189Recruiting
Adjusting gas flow during heart-lung machine rewarming
This study tests how adjusting the amount of sweep gas (a gas mixture) during the rewarming phase of heart-lung machine use might affect patients. It's for people having planned heart surgery with a standard heart-lung machine, not minimally invasive or robotic surgery.
Istanbul, AltunizadeAges 18 years+ - NCT07857811Recruiting
Blood pressure monitoring in young children during heart surgery
This study looks at how blood pressure readings from the arm compare to readings from the aorta during heart surgery with a heart-lung machine in children up to 3 years old. It aims to improve blood pressure monitoring during and after surgery.
Santiago, Santiago MetropolitanAges birth–3 years - NCT02884271Recruiting
Study CPR during surgery when the heart stops
This trial looks at cardiopulmonary resuscitation (CPR) provided right in the operating room when a patient’s heart stops. It may help improve how emergency care is delivered during surgery.
IzmirAges Any age - 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 - NCT07795112Recruiting
Acupuncture for reducing inflammation after heart surgery
This study tests whether acupuncture at a specific point (ST36) can reduce inflammation after heart surgery. If you are having heart surgery with a bypass machine, you may be able to join and receive this additional treatment to help your recovery.
Hangzhou, ZhejiangAges 18 years+ - NCT07778823Recruiting
Augmented reality support for CPR in children
This study tests whether augmented reality (a headset that projects images) can guide nurses and technicians during CPR on children. You may be asked to perform chest compressions while using this technology to see if it helps improve performance.
St. Petersburg, FloridaAges 18 years+ - NCT05924555Recruiting
Exercise testing in inherited fatty acid breakdown disorders
This study checks how well people with long-chain fatty acid breakdown disorders tolerate exercise. It may help doctors better understand exercise limits and how to manage symptoms during activity.
Amsterdam, North HollandAges 18 years+ - NCT07683299Recruiting
New heart monitoring during bypass surgery
This study tests a new way to monitor your heart and blood flow during heart surgery that uses a heart-lung machine. The goal is to see if this integrated approach helps doctors make better decisions during the operation.
Medellín, AntioquiaAges 18 years+ - NCT07632131Recruiting
Storytelling therapy to prevent PTSD after heart surgery
This study tests whether a special therapy called narrative exposure—where you talk through your surgery experience with a trained counselor—can help prevent PTSD (post-traumatic stress) in people recovering from heart surgery in the ICU. The goal is to help you process what happened so you feel less distressed afterward.
Fuzhou, FujianAges 18 years+ - NCT07591987Recruiting
Breathing Techniques to Reduce Shortness of Breath After Heart Surgery
This study tests whether special breathing exercises can help reduce shortness of breath and improve heart and lung function in patients recovering from open-heart surgery. You would learn and practice these breathing techniques before and after your surgery.
Baghdad, Baghdad GovernorateAges 18–75 - NCT07549243Recruiting
Ear Nerve Stimulation to Protect Kidneys During Heart Surgery
This trial tests whether gentle electrical stimulation applied to your ear can help protect your kidneys during heart surgery that uses a heart-lung machine. Kidney damage after this type of surgery is common, and researchers want to see if this non-invasive stimulation can prevent it.
Hangzhou, ZhejiangAges 18 years+ - NCT07529145Recruiting
Heart and Lung Fitness Testing During Lung Cancer Treatment
This study measures how well your heart and lungs work before and during lung cancer treatment using an exercise test. The goal is to understand how cancer treatment affects your physical fitness and help doctors better monitor your health.
Bialystok, Podlaskie VoivodeshipAges 18 years+ - NCT07519733Recruiting
Exercise Testing Before High-Risk Surgery
This study tests whether a simple exercise test before surgery can help doctors better predict and prevent complications in older adults undergoing major operations. You'll do a gentle exercise test on a stationary bike or treadmill to measure your fitness level.
New Haven, ConnecticutAges 45 years+ - NCT06780514Recruiting
Exercise testing for girls with Turner syndrome
This study will have girls with Turner syndrome do a cardiopulmonary exercise test (a special bike or treadmill test) to check how their heart and lungs work during exercise. It may help doctors better understand fitness and health in Turner syndrome.
GhentAges 8–18 - NCT06789978Recruiting
Quick ECPR for cardiac arrest in Prague
This study tests a rapid way to give life support using a heart-lung bypass machine (ECPR) to people experiencing a sudden cardiac arrest that doesn't stop with defibrillators or standard CPR. The goal is to start this treatment within 20 minutes of the emergency call, which may improve chances of survival.
Prague, CzechiaAges 18–70 - NCT07390903Recruiting
Heart function test for difficult bypass weaning
This trial studies whether a heart ultrasound test called GLS can help predict complications when patients are taken off the heart-lung machine after heart surgery. It aims to improve management for better outcomes.
RomeAges 18 years+ - NCT07382206Recruiting
Exercise and Sleep in PLMS: A Wearable Device Study
This study tests whether a single session of exercise can improve sleep in people with periodic limb movements during sleep (PLMS). It uses a smartwatch and ring to track sleep patterns and compares results to a control group without PLMS.
São Paulo, São PauloAges 22 years+ - NCT07363772Recruiting

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.
