Summary

This trial is exploring a new treatment for post COVID-19 symptoms, such as fatigue, using hyperbaric oxygen therapy. The findings could help decide if this treatment is feasible for a large-scale research study.

Who is the study for?
Adults diagnosed with post COVID-19 condition, experiencing chronic fatigue and at least one other symptom like 'brain fog' or anxiety for over 12 weeks since infection. Excludes those with traumatic brain injury, unstable living situations, pregnant women or those planning pregnancy, pre-existing cognitive issues, and anyone unfit for hyperbaric treatments.
What is being tested?
The trial is testing hyperbaric oxygen therapy—a treatment where patients breathe high levels of oxygen in a special chamber—to see if it can alleviate symptoms of post COVID-19 condition such as persistent fatigue and 'brain fog'.
What are the potential side effects?
While not specified here, common side effects of hyperbaric oxygen therapy may include ear pressure changes leading to discomfort or pain, temporary vision changes, and rarely lung collapse due to air pressure changes.
