What Researchers Did
Researchers exposed people to hyperbaric hyperoxia for 24 hours to observe changes in their blood plasma.
What They Found
Before exposure to hyperbaric hyperoxia, blood plasma showed strong erythropoietic activity. After 24 hours of hyperoxic conditions (25% oxygen at 63 meters depth), erythropoietins completely vanished, and erythropoiesis inhibitors appeared in the plasma of untrained individuals. This was accompanied by a decrease in peripheral red blood cell counts.
Canadian Relevance

Study Limitations
This study is limited by its age, lack of detail on participant numbers or specific health conditions, and the absence of a control group.
