What Researchers Did
Researchers compared the accuracy of a point-of-care capillary blood glucose meter against laboratory venous serum samples in ten non-diabetic participants undergoing hyperbaric oxygen treatment.
What They Found
They found statistically significant differences in capillary blood glucose readings between pre-treatment (T1) and during hyperbaric oxygen treatment (T2: P = 0.001; T3: P < 0.001), suggesting an effect of hyperbaric oxygen on capillary beds. While the highest venous serum value was 5.90 mmol·L⁻¹ at T3, and the highest capillary value was 6.30 mmol·L⁻¹ at T1, venous glucose levels showed no significant changes across time points.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
A limitation of this study is its small sample size of ten non-diabetic participants, which may limit the generalizability of the findings.
