What Researchers Did
Researchers investigated how hyperbaric oxygen therapy affects the way the human body processes caffeine in two healthy volunteers.
What They Found
The study found that caffeine's pharmacokinetic parameters, such as its peak concentration (Cmax) and elimination half-life (T1/2), were similar to established normal values. For example, Volunteer 1 had a Cmax of 6.13 mg/L and T1/2 of 180 minutes, while Volunteer 2 had a Cmax of 6.23 mg/L and T1/2 of 283 minutes. Statistical tests showed no significant changes in caffeine processing during 110 minutes of hyperbaric oxygen at 2.5 ATA, alternating 100% oxygen and air breathing.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
A significant limitation of this study is its very small sample size, involving only two human volunteers.
