What Researchers Did
Researchers analyzed spirometry data from 14 hyperbaric oxygen therapy personnel between 2012 and 2023 to assess long-term lung function changes due to hyperbaric exposure.
What They Found
The study found no significant differences in FVC, FEV1, or PEF before and after hyperbaric exposures (P > 0.05). However, FEF25-75, a small airway function indicator, showed a 16% reduction in personnel with over 150 HBOT sessions (P = 0.038), with a significant difference between those with fewer than 74 and those with 150 or more sessions (P = 0.015).
What This Means for Canadian Patients
For Canadian patients undergoing hyperbaric oxygen therapy, this study highlights the importance of ensuring the well-being of the inside attendants who accompany them. Maintaining the health of these personnel helps ensure safe and effective treatment delivery for patients.
Canadian Relevance
This study has no direct Canadian connection as it was not conducted in Canada nor involved Canadian participants or institutions.
Study Limitations
The small sample size of 14 personnel and the lack of clinically significant symptoms reported are key limitations of this study.
