Summary

This trial will see if oxygen during sleep can help kids with Down Syndrome and severe sleep apnea improve memory and other health outcomes.

Who is the study for?
This trial is for children and teens aged 5 to 17.9 with Down Syndrome who have moderate to severe Obstructive Sleep Apnea (OSA). They should be able to perform neuropsychological tests, not use CPAP regularly or take supplemental oxygen, and must not have other severe chronic diseases or untreated hypothyroidism.
What is being tested?
The study is testing if giving extra oxygen during sleep can help improve working memory and other outcomes in kids with Down Syndrome who also suffer from OSA. The oxygen flow won't exceed certain limits, ensuring safety.
What are the potential side effects?
Potential side effects may include discomfort from wearing the oxygen delivery device and dry or irritated nasal passages due to the flow of oxygen.
