What Researchers Did
Researchers conducted a systematic review to synthesize existing evidence on the effects of hyperbaric oxygen therapy (HBOT) for sleep breathing disorders (SBD), including obstructive sleep apnea (OSA), central sleep apnea (CSA), and altitude-related sleep disturbances.
What They Found
The review found promising but preliminary evidence suggesting hyperbaric oxygen therapy (HBOT) may benefit selected sleep breathing disorder populations. HBOT's potential therapeutic effects include reducing inflammation and oxidative stress, reversing tissue hypoxia, and improving pulmonary function and oxygenation.
What This Means for Canadian Patients
Canadian patients with sleep breathing disorders who struggle with conventional treatments might eventually consider hyperbaric oxygen therapy as an adjunctive or alternative option. However, this therapy is still under investigation, and its widespread use would require more robust clinical evidence.
Canadian Relevance
This systematic review does not have a direct Canadian connection.
Study Limitations
The interpretation of the findings is limited by heterogeneity in study protocols, small sample sizes, and a lack of long-term follow-up in the included studies.
