Continuous skin carbon dioxide monitoring in heart-lung bypass patients
This study checks whether a sensor placed on the skin can reliably measure carbon dioxide levels in people who need VA-ECMO, a kind of temporary heart-lung support. It aims to help doctors monitor breathing and circulation more accurately while you’re on this support.
ViennaAges 18–90 - NCT06321497Recruiting
Carbon dioxide removal to protect lungs during ARDS
This study tests a machine that removes carbon dioxide from your blood (called extracorporeal carbon dioxide removal or ECCO2R) to help protect your lungs from further damage while on a breathing machine. It may be an option if you have severe ARDS and your breathing machine settings are very high.
Frankston, VictoriaAges 18 years+ - NCT06934876Recruiting
Comparing two CO2 detectors during breathing tube placement in critically ill adults
This study compares two ways of checking that a breathing tube is placed correctly in seriously ill adults: one uses a device that shows a waveform on a screen, and the other uses a color-changing test. It may help doctors choose the best method for patients in the emergency room or ICU.
Chicago, IllinoisAges 18 years+ - NCT04962646Recruiting
Breathing extra carbon dioxide during surgery to prevent brain injury
This trial tests whether giving extra carbon dioxide during surgery can reduce the chance of new brain or nervous system injury after surgery for a sudden, life-threatening tear in the big artery (type A aortic dissection). It may help by protecting the brain while the surgical team repairs the artery.
LundAges 18 years+ - NCT07326449Enrolling by invitation
CO2 measurement test on exercise bike
This trial checks if a portable device can reliably measure carbon dioxide in your breath while you rest and cycle slowly. It may help understand how your lungs work during light exercise.
LinköpingAges 18–70 - NCT07734584Recruiting
Reducing air bubbles during aortic repair with carbon dioxide
This trial tests a special flushing method using carbon dioxide gas to prevent air bubbles from entering the bloodstream during a procedure to fix the main artery in the chest. This could help avoid strokes or other complications.
Bologna, ItalyAges 18 years+ - NCT04134754Recruiting
Testing how your brain responds to carbon dioxide in epilepsy
This study measures how sensitive your brain is to higher carbon dioxide levels to learn more about sudden unexpected death in epilepsy (SUDEP). You may be invited because you have epilepsy and are having evaluation at a specialized epilepsy unit or clinic.
Iowa City, IowaAges 18–99 - NCT06338865Recruiting
Lower pressure vs. standard pressure for laparoscopic gynecologic surgery
This trial compares using lower gas pressure during minimally invasive gynecologic surgery to the standard pressure. The goal is to see if lower pressure reduces pain and speeds recovery after surgery.
Los Angeles, CaliforniaAges 18 years+ - NCT07776444Recruiting
Measuring brain blood flow with light and MRI
This study uses a special light-based device and MRI to measure how blood vessels in the brain respond to changes. It may help researchers better understand blood flow in people with and without sickle cell disease.
St Louis, MissouriAges 6–70 - NCT07770386Recruiting
Predicting heart trouble after child heart surgery
This study looks at whether a simple blood test can predict a serious heart problem called low cardiac output syndrome after a child has heart surgery. Doctors hope this will help them spot and treat this issue earlier, which could lead to better recovery for your child.
LilleAges Up to 17 years - NCT07561242Recruiting
Skin response to fractional laser treatments in darker skin tones
This study measures how skin changes after two types of laser treatments (gentler and stronger) on the forearm. Researchers want to understand how these lasers work on darker skin types to improve safety and results.
Shanghai, Shanghai MunicipalityAges 18–60 - NCT07472192RecruitingPhase 2
Laser treatment with or without PDRN for facial scars
This study tests if adding a substance called PDRN to a laser treatment helps improve the look of new facial scars better than laser alone. PDRN may help the skin heal more smoothly.
GizaAges 18–50 - NCT07463742Recruiting
Genetic changes in tracheal narrowing with two treatments
This trial studies genetic changes in people with tracheal stenosis (narrowing of the windpipe). It compares two treatments: wedge resection (cutting out the narrow part) and radial incision (cutting to open it up). This may help doctors choose the best treatment in the future.
Baltimore, MarylandAges 18–80 - NCT07435844Recruiting
Spa care for kidney and urinary health in adults
This study tests whether a comprehensive spa program can help adults with chronic kidney or urinary tract conditions like infections, stones, or after surgery. It's designed for patients who have not responded well to standard medications.
Mariánské Lázně, Carlsbad RegionAges 40–70 - NCT07420530RecruitingPhase 2
Exercise and breathing study for young adults with vocal cord issues
This study looks at how the vocal cords move during exercise in young adults who have trouble breathing while active. It may help researchers understand why this happens and how to better diagnose and treat it.
Bloomington, IndianaAges 18–26 - NCT07357090Recruiting
Carbon dioxide and brain waste clearance trial
This trial tests if breathing in carbon dioxide helps the brain clear waste. It may show how the brain heals after a traumatic brain injury (TBI).
Albuquerque, New MexicoAges 18–82 - NCT07352215Recruiting
Platelet-rich plasma plus CO2 laser for acne scars
This study tests whether combining your own blood proteins (PRP) with a fractional CO2 laser can improve moderate-to-severe acne scars more than laser alone. You would have 3 treatment sessions spaced several weeks apart.
Gujranwala, Punjab ProvinceAges 18–40 - NCT07326215Recruiting
A study of a device that removes carbon dioxide from the blood
This trial tests a device called PrismaLung+ that helps remove extra carbon dioxide from the blood of patients on breathing machines. It may help people whose lungs are struggling despite gentle ventilation settings.
Beijing, Beijing MunicipalityAges 18 years+ - NCT07262125Enrolling by invitation
Carbon dioxide pressure and eye nerve sheath in kidney surgery
This study looks at how the carbon dioxide gas used during keyhole kidney cancer surgery affects the pressure behind your eye. The goal is to see if changes in gas pressure influence the nerve sheath that surrounds the optic nerve.
Istanbul, AtaşehirAges 31–69 - NCT07211763Recruiting
Comparing carbon dioxide checks during jet ventilation for liver tumor ablation
This study looks at two ways of measuring carbon dioxide levels during a special type of breathing support called jet ventilation. The goal is to see if less invasive checks work as well as standard ones for people having a procedure to treat liver tumors with heat (radiofrequency ablation).
GothenburgAges 18 years+ - NCT07179276Recruiting
Testing CO₂ gap to guide septic shock treatment
This trial checks if measuring the carbon dioxide gap (a sign of how well blood is flowing to organs) can help doctors improve treatment for people in septic shock. Septic shock is a severe infection that causes very low blood pressure and organ damage.

Common questions
- Are there clinical trials for carbon dioxide?
- Yes. Clin2 currently lists 35 recruiting carbon dioxide 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 carbon dioxide 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 carbon dioxide 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.
