Recruiting studies
- NCT07624409Enrolling by invitationEarly Phase 1
Occupational health study for high-altitude workers
This study examines how working at high altitudes (where there is less oxygen in the air) affects employees at an astronomical observatory in Chile. Researchers want to understand health impacts and develop better support for people working in these extreme conditions.
San Pedro de Atacama, AntofagastaAges 20–50 - NCT07431567Recruiting
How low oxygen affects heart function in healthy adults
This study tests how your heart’s right ventricle handles low oxygen (like at high altitude) in healthy adults. You will be exposed to a low-oxygen environment for a short time to see how your heart responds.
Zurich, Canton of ZurichAges 18–80 - NCT07431554Recruiting
Studying heart function in low oxygen after HAPE
This study looks at how the right side of the heart responds to low oxygen levels in people who have had high altitude pulmonary edema (HAPE) in the past. It will help researchers better understand right heart function.
ZurichAges 18–80 - NCT07431580Recruiting
How low oxygen affects heart function in asthma
This study tests how your heart's right ventricle adapts when you breathe lower-oxygen air (like at high altitude). If you have well-controlled asthma, researchers want to see if your heart handles the challenge differently.
Zurich, Canton of ZurichAges 18–80 - NCT06930027Enrolling by invitation
Low-oxygen training for ice hockey players
This study tests whether training in a low-oxygen environment (hypoxia) can boost strength and power in ice hockey players. Researchers want to see if it helps improve your explosive movements and muscle function.
Katowice, Silesian VoivodeshipAges 18–35 - NCT03255408RecruitingPhase 1/Phase 2
Sleep study testing breathing and blood flow in healthy adults
This study looks at how your brain blood flow and breathing change during sleep under normal oxygen and reduced oxygen. It will only include healthy adults so researchers can learn what “intermittent hypoxia” does to the body in people without medical problems.
Calgary, AlbertaAges 18–45 - NCT06912230Recruiting
How low oxygen affects appetite in young women
This study looks at how breathing air with less oxygen affects hunger and how much young women eat. It may help us understand appetite control in different environments.
Ottawa, OntarioAges 18–30 - NCT07739992Recruiting
Acute intermittent hypoxia for spinal cord injury
This study tests a breathing therapy called acute intermittent hypoxia, which involves short bursts of low oxygen, to see if it can improve leg movement in people with spinal cord injury. It may help strengthen the muscles that lift the foot.
Chicago, IllinoisAges 18–75 - NCT05048680Recruiting
Breathing low-oxygen training to support brain blood flow in seniors
This study tests whether brief “low-oxygen” conditioning can improve blood flow to the brain and overall cerebrovascular (brain blood vessel) health in older adults. It may help people who are generally less active, as long as they have no major medical or safety barriers for the training.
La Tronche, Auvergne-Rhône-AlpesAges 60–80 - NCT06276634Recruiting
Low-Oxygen Therapy for People With Multiple Sclerosis
This study tests whether brief, controlled low-oxygen episodes (called intermittent hypoxia) can improve motor function in people with MS. It may help strengthen walking and daily movement.
Chicago, IllinoisAges 18–75 - NCT06390930Recruiting
Breathing bursts of lower oxygen for hand function in MS
This study tests whether breathing short bursts of reduced oxygen (acute intermittent hypoxia) can improve hand function and nerve health in people with relapsing-remitting MS who have some hand weakness.
Chicago, IllinoisAges 18–75 - NCT06846034Recruiting
How low oxygen affects kidney blood flow
This study tests how low oxygen levels affect blood flow in the kidneys. It includes healthy people, people with type 2 diabetes, and those with diabetes plus kidney disease to see if their kidneys respond differently.
PoitiersAges 18–75 - NCT07002437Recruiting
Low oxygen for early spinal cord recovery
This study tests whether mild, short-term low oxygen levels (like at high altitude) can help the spinal cord recover earlier after an injury. It is for people who had a spinal cord injury in the last 2 weeks to 6 months.
Jacksonville, FloridaAges 18–70 - NCT06896773Enrolling by invitation
Training in low oxygen conditions and heart health
This study tests whether training in a room with less oxygen (like being at high altitude) changes heart health markers in male cyclists. It may help understand if this type of training is safe and effective.
Warsaw, Masovian VoivodeshipAges 20–40 - NCT04691518Enrolling by invitation
Testing intermittent low-oxygen sessions in healthy adults
This study tests whether breathing lower-oxygen air in short breaks changes how the brain and body respond. It is only for medically stable, healthy adults with specific safety screening.
Chicago, IllinoisAges 18–70 - NCT05351827Recruiting
Mild intermittent hypoxia for autonomic function in spinal cord injury
This study is testing whether mild intermittent hypoxia (brief episodes of reduced oxygen) can improve autonomic nervous system function (which controls things like blood pressure and heart rate) in people with incomplete spinal cord injuries. It may help reduce symptoms like dizziness or irregular heart rate.
Detroit, MichiganAges 18–60 - NCT06226168Recruiting
Hypoxia exercise for bone health in premenopausal women
This study looks at how an exercise program done in low-oxygen (hypoxia) conditions affects bone health and metabolism in premenopausal women. It could help if you're interested in improving your bone density naturally.
KrakowAges 50–59 - NCT06459206Recruiting
Testing a smart ring's oxygen sensor during low oxygen levels
This study checks how well a special ring (EvieMED Ring) measures oxygen in your blood when oxygen levels are made very low in a controlled setting. It helps see if the ring is accurate for people with serious health conditions.
San Francisco, CaliforniaAges 18–49 - NCT07335536Recruiting
Remimazolam for safer sedation during egg retrieval
This trial tests if remimazolam, a sedative, can reduce low oxygen levels during a procedure to collect eggs from the ovaries. It may be a safer option for people having this fertility treatment.
Dongyang, ZhejiangAges 18–50 - NCT06108089Recruiting
Hypoxia imaging for head and neck cancer treatment planning
This study uses a special MRI scan to measure oxygen levels in your head and neck tumor. The goal is to learn if this scan can help doctors choose the best treatment plan for you.
Salt Lake City, UtahAges 18 years+ - NCT03736382Recruiting
Study how mild low-oxygen affects sleep apnea and blood pressure
This trial studies whether mild, controlled low oxygen during sleep can change sleep apnea symptoms and related blood pressure issues. It mainly looks at people with newly diagnosed, untreated sleep apnea and early high blood pressure.
Detroit, MichiganAges 18–60 - NCT03949049RecruitingPhase 3
Citi-coline for babies who had low oxygen at birth
This trial studies whether a medicine called citicoline can protect the brain in newborns who had low oxygen (hypoxia). It may help reduce brain injury in babies, but it does not include babies with a specific severe brain condition.
CairoAges Up to 1 month - NCT04007432Recruiting
Testing nighttime low-oxygen levels after hip fracture surgery
This study checks how often older adults get low oxygen during the night after hip fracture surgery. It may help doctors better monitor and improve care during hospital recovery.

Blood inflammation test study in sudden brain oxygen loss
This trial looks at blood “inflammation-related” biomarkers to understand what happens early after certain sudden brain events. It may help doctors predict outcomes and tailor treatment for people like those with stroke types that sometimes need a clot-removal procedure.

Common questions
- Are there clinical trials for hypoxia?
- Yes. Clin2 currently lists 121 recruiting hypoxia 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 hypoxia 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 hypoxia 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.
