Summary

What Researchers Did

Researchers treated six patients experiencing long-lasting COVID-19 symptoms with hyperbaric oxygen therapy and assessed their symptoms before, during, and after treatment.

What They Found

All six patients showed improvements in measured symptoms after hyperbaric oxygen therapy. Specifically, five of six patients returned to their pre-infection symptom levels, while the remaining patient experienced significant symptom improvement. These results suggest HBO2 therapy improved symptom scores, reduced symptom duration, and enhanced quality of life.

Canadian Relevance

This study has no direct Canadian connection as it was not conducted in Canada nor involved Canadian researchers or participants.

Study Limitations

The main limitation of this study is its very small sample size of only six patients, which prevents generalizable conclusions and necessitates larger, randomised controlled trials.
