What Researchers Did
Researchers presented a case study of a recreational diver who developed severe decompression sickness, including difficulty speaking, and described how advanced brain monitoring was used during his hyperbaric oxygen treatment.
What They Found
A 64-year-old male diver experienced expressive aphasia, vertigo, and right-sided weakness 30-120 minutes after surfacing from a deep dive. Initial brain monitoring showed significant asymmetry between brain hemispheres, which progressively resolved over three hyperbaric oxygen sessions. The patient achieved full clinical recovery after four sessions, coinciding with the resolution of this brain activity asymmetry.
Canadian Relevance
This study covers decompression sickness, which is a Health Canada-recognised indication for hyperbaric oxygen therapy.
Study Limitations
As a single case report, the findings may not apply to all patients with decompression sickness.
