Nocturnal Oxygen for Hypoxia
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores how nighttime oxygen levels affect heart activity in individuals with and without lung disease. Participants will receive nocturnal oxygen therapy for four hours while researchers study changes in heart function. This trial suits those with a chronic respiratory condition with low oxygen levels or healthy individuals who can give consent. As an unphased trial, it offers a unique opportunity to contribute to scientific understanding and potentially improve future treatments.
Do I have to stop taking my current medications for the trial?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators.
What prior data suggests that nocturnal oxygen is safe for individuals with and without lung disease?
Research has shown that using oxygen at night is generally safe for people with lung disease. One study found that patients who used oxygen while sleeping had a lower risk of dying over two years compared to those who didn't use it. Another study found that using oxygen at night did not harm breathing during sleep, even at high altitudes. While these studies suggest that using oxygen at night is usually well-tolerated, some people might still experience minor side effects. Always consult a healthcare provider to understand personal risks.12345
Why are researchers excited about this trial?
Most treatments for hypoxia in lung disease focus on daytime oxygen supplementation or medications to improve lung function. However, the use of nocturnal oxygen therapy is unique because it specifically targets low oxygen levels during sleep. This approach may help improve overall oxygen saturation and reduce complications that arise from nighttime hypoxia. Researchers are excited about this treatment because it could offer a more tailored and potentially more effective way to manage hypoxia, especially for those whose oxygen levels drop significantly during sleep.
What evidence suggests that nocturnal oxygen is effective for hypoxia?
This trial will compare the effects of nocturnal oxygen therapy in two groups: individuals with lung disease experiencing nocturnal hypoxemia and healthy individuals. Research has shown that using oxygen therapy at night might address certain issues caused by low oxygen levels during sleep. For example, one study found that it can improve the outlook for people with COPD, a lung disease, who have low oxygen at night, though it doesn't necessarily extend their lifespan. Another study discovered that using oxygen at night can prevent low oxygen levels and breathing problems during sleep for some people. However, some research did not find clear proof that using oxygen at night changes overall health outcomes, such as longevity or the need for long-term oxygen. In summary, while using oxygen at night may help with breathing problems during sleep, its broader benefits remain uncertain.26789

Are You a Good Fit for This Trial?
This trial is for individuals who can consent and have a chronic respiratory condition with oxygen saturation below 95% when not using supplemental oxygen. It's not for those with severe obesity, recent heart issues, uncontrolled medical conditions like angina or high blood pressure, cancer, or active major depression.Inclusion Criteria
