Summary

Research hypothesis

* Diving to depths up to 90msw with an oxygen partial pressure of 130kPa in the breathing gas will affect the central nervous system.
* Diving to depths up to 90msw with an oxygen partial pressure of 130kPa in the breathing gas will induce inflammatory changes.

Objectives:

* To investigate the presence of cerebrospinal biochemical markers in blood after diving to depths up to 90msw with an oxygen partial pressure of 130kPa in the breathing gas.
* To investigate the presence of inflammatory markers in blood after diving to depths up to 90msw with an oxygen partial pressure of 130kPa in the breathing gas.
* To investigate the presence of venous gas emboli (VGE) in blood after diving to depths up to 90msw with an oxygen partial pressure of 130kPa in the breathing gas.
