Summary

What Researchers Did

Researchers developed a mathematical model to predict central nervous system oxygen toxicity in humans during complex dives, considering varied metabolic rates and inspired CO2 levels.

What They Found

They established a power equation K = t2(PO2/101.3)C for humans, where c was 6.76 and a symptom might appear when K reached a threshold Kc = 2.31 X 10(8). The predicted risk from this model agreed with reported risks in composite exposures, and they derived an equation to calculate mean time to toxicity based on metabolic rate.

Canadian Relevance

This study has no direct Canadian connection.

Study Limitations

A key limitation is the reliance on assumed similar relationships between rat and human data for some parameters, requiring further human-specific validation.
