Hyperbaric oxygen therapy is generally safe, but clinical literature confirms it carries notable side effects and risks, such as middle ear and sinus barotrauma, oxygen toxicity, and hypoglycemia.
The claim is specific, empirical, and falsifiable. Multiple retrieved papers directly document the side effects and risks associated with hyperbaric oxygen therapy, such as barotrauma, oxygen toxicity, and hypoglycemia, while none refute that risks exist. Thus, the evidence clearly supports the claim.
