What Researchers Did
Researchers conducted a narrative review to compare the physiological effects, clinical uses, and safety of mild and traditional hyperbaric oxygen treatments.
What They Found
This narrative review found that traditional hyperbaric oxygen treatment promotes wound healing but is linked to adverse events, while mild hyperbaric oxygen treatment may benefit microcirculation and metabolism. Traditional HBOT causes systemic hyperoxia, which helps wound healing but can lead to oxygen free radical damage. Mild HBOT, using lower oxygen, might reduce oxidative damage and improve peripheral microcirculation, parasympathetic activity, and metabolism, though its use for wound treatment is not widely studied. Both types of HBOT carry serious risks, including chamber explosion and fire, which can be reduced by following safety standards.
What This Means for Canadian Patients
Canadian patients considering hyperbaric oxygen therapy should be aware of the differences between traditional and mild treatments, especially regarding their potential benefits for conditions like wound healing and their associated safety risks. Understanding these distinctions can help patients discuss the most appropriate and safest HBOT options with their healthcare providers.
Canadian Relevance
This study is not Canadian. However, its discussion of traditional HBOT's role in wound healing aligns with Health Canada-recognized indications such as diabetic foot ulcers.
Study Limitations
A limitation of this review is that mild hyperbaric oxygen treatment has not been extensively studied as a wound treatment, and compliance with safety standards for both types of HBOT can vary among facilities.
