Summary

What Researchers Did

Researchers used low temperature electron spin resonance (ESR) spectroscopy to examine blood from individuals undergoing hyperbaric oxygen (HBO) exposure and conducted in vitro studies on blood.

What They Found

They observed a marked increase in a free radical signal (g = 2.006) in the blood of individuals exposed to HBO. This signal diminished to baseline levels within 10 minutes of cessation of HBO exposure, and in vitro studies suggested it was an ascorbate radical.

Canadian Relevance

This study has no direct Canadian connection as it was not conducted in Canada or by Canadian researchers.

Study Limitations

The study postulates the mechanism of free radical increase, suggesting further research is needed to confirm the exact biochemical pathways involved.
