What Researchers Did
Researchers reviewed published experimental and clinical studies to summarize what is currently known about the potential role of HBOT as a supporting treatment for asthma.
What They Found
Preclinical and small clinical studies suggest HBOT may reduce airway inflammation, lower oxidative stress, modulate immune responses, and improve lung function in asthma. However, existing clinical evidence is limited and inconclusive, no large randomised controlled trials have confirmed whether HBOT works for asthma. Potential risks include barotrauma and oxygen toxicity.
Canadian Relevance
No direct Canadian connection identified. HBOT for asthma is not OHIP-covered in Ontario.
Study Limitations
This is a narrative review without a systematic methodology, and the clinical evidence it draws from consists mostly of small, poorly designed studies.
