Remote Ischemic Conditioning for High-Altitude Blood Thickening
Part of Blood & lymphatic clinical trials.
This trial tests whether a safe, non-invasive treatment called remote ischemic conditioning can help people living at high altitude who have developed thick blood (too many red blood cells). The treatment involves briefly reducing blood flow to the arm using a special cuff, which may help reduce excess red blood cell production.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are at least 18 years old
- You have lived continuously at high altitude (2,500+ meters or 8,200+ feet) for more than 6 months and plan to stay there
- You have been diagnosed with high-altitude polycythemia (excess red blood cells caused by living at high altitude)
- You have no severe heart, liver, kidney, or lung disease
- You have no active cancer, uncontrolled thyroid problems, or poorly controlled diabetes
- You do not have serious blood vessel problems or recent injuries in your upper arms

This study looks at high-altitude polycythemia, a condition where your body makes too many red blood cells in response to living at high altitude. Researchers want to learn more about this condition and how to help people who have it.
This study tests whether a non-invasive treatment called remote ischemic conditioning—brief cycles of squeezing and releasing blood flow in the arm—can help lower blood pressure in people living at high altitude. The goal is to see if this method works better than standard care alone.
This trial studies whether a simple, at-home type of treatment using brief arm blood-flow changes can improve blood flow to the heart and outcomes after CABG (heart bypass surgery). It may help some people recover better by protecting the heart around the time of surgery.
This study tests a non-invasive method called remote ischemic conditioning, which involves brief cycles of inflation and deflation of a blood pressure cuff on the arm. It may help improve health outcomes for people with spinal cord injury who are not currently able to exercise.
This study tests a simple, non-invasive treatment called remote ischemic conditioning (using a blood pressure cuff to briefly stop blood flow to one arm) to see how it affects heart and blood flow in critically ill patients in the ICU. If you are in the ICU, over 18, and have a special heart monitor, you may be able to join.
This trial studies “erythrocytapheresis,” a procedure that filters part of the blood, to improve symptoms of chronic mountain sickness caused by long-term living at high altitude. It may help people with high-altitude–related headaches, dizziness, shortness of breath, poor sleep, fatigue, and related signs.
