What Researchers Did
Researchers investigated how the blood's ability to produce red blood cells changed after people were exposed to high-pressure air conditions.
What They Found
They observed a significant drop in the blood plasma's erythropoietic activity, which signals red blood cell production, 18 to 20 hours after exposure to compressed air at a depth equivalent to 100 metres. However, no statistically significant changes were found in other peripheral blood measurements during that same period.
Canadian Relevance
No direct Canadian connection identified.
