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 - 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 - 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 - 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 - 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 - NCT07516028Recruiting
How Your Brain Responds to Low Oxygen Levels
This study looks at how your brain's nerve signals change when exposed to moderate low-oxygen conditions. Researchers will use brain stimulation and imaging to understand these changes, which could help future treatments for brain and spinal cord conditions.
Loos, Hauts-de-FranceAges 18–65 - 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 - 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 - 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 - 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 - 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 - 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 - 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 - 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 - NCT07333599Recruiting
Study of low oxygen in full-term newborns
This study looks at full-term babies born with very low cord blood pH (a sign of oxygen shortage). It aims to understand different patterns of low oxygen and how they affect newborns. Doctors hope this can improve care for babies with similar issues.
StrasbourgAges birth–1 day - NCT07307560Recruiting
High-flow oxygen during sedation for sleep apnea patients having endoscopy
This study tests if high-flow nasal oxygen can prevent oxygen drops during sedated endoscopy in patients with severe obstructive sleep apnea. It may help people who are at higher risk of breathing problems during the procedure.
Hangzhou, ZhejiangAges 18 years+ - 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.
ParisAges 70 years+ - NCT07173543Recruiting
Type 2 Diabetes and Brain Health Study for Adults 60–85
This study looks at how type 2 diabetes affects blood flow in the brain and thinking ability. It compares people with diabetes to those without, and may help understand how to protect brain health.

Treating Muscle Stiffness After Spinal Cord Injury With Oxygen Therapy
This study tests whether brief periods of low oxygen (called acute intermittent hypoxia) can reduce muscle stiffness and tightness that develops after a spinal cord injury. Researchers believe this approach may help improve arm and hand function.
Chicago, IllinoisAges 18 years+ - NCT07035028Recruiting
Scalp stimulation test for baby's oxygen levels during labor
This trial tests a simple, non-invasive scalp stimulation on your baby's head during labor to see if it can predict whether your baby is getting enough oxygen, potentially avoiding the need for a more invasive blood test.
MadridAges 18–50 - NCT06906536Enrolling by invitation

Common questions
- Are there clinical trials for hypoxia?
- Yes. Clin2 currently lists 112 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.
