What Researchers Did
Researchers investigated the effect of hyperbaric oxygenation on external respiration in 53 patients experiencing acute cerebral circulatory disorders using spirography.
What They Found
In 53 patients, hyperbaric oxygenation normalized initially abnormal external respiration, correcting periodic rhythms and reducing hyperventilation. It had no effect on initially normal respiration, and the respiratory response to hyperbaric oxygen changed over the course of treatment. The study also noted that hyperventilation appearing after one or three sessions without negative neurological changes should not be considered a contraindication for hyperbarotherapy.
What This Means for Canadian Patients
For Canadian patients with acute cerebral circulatory disorders, hyperbaric oxygenation may help normalize abnormal breathing patterns, such as periodic rhythms and hyperventilation. This suggests that hyperbaric oxygen therapy could be a beneficial intervention for improving respiratory function in this patient group, even if mild hyperventilation occurs early in treatment.
Canadian Relevance
This study has no direct Canadian connection as it was conducted in a different geographical region and published in a Russian journal.
Study Limitations
The study's findings are limited by its relatively small sample size of 53 patients and its age, as medical practices have evolved significantly since 1982.
