Summary

This study is testing whether hyperbaric oxygen therapy (HBOT) can help people with Long COVID who have brain fog, fatigue, and other lingering symptoms. HBOT delivers high levels of oxygen to the body, which may reduce inflammation and improve blood flow to the brain. The trial will enroll 120 adults who had COVID-19 at least 3 months ago and still have symptoms.
