What Researchers Did
Researchers investigated changes in the chemical balance of blood and cerebrospinal fluid in patients with ischaemic stroke while they underwent hyperbaric oxygen therapy.
What They Found
A common observation was compensated metabolic acidosis in the cerebrospinal fluid, which was more pronounced in patients with extensive brain damage. This acidosis was also found in the venous blood of the brain. Patients receiving hyperbaric oxygen therapy showed a significant decrease in metabolic acidosis in their cerebral venous blood compared to a control group.
