Research hypothesis

– Prolonged hyperbaric exposure will affect the central nervous system

– Prolonged hyperbaric exposure will induce inflammatory changes

– Prolonged hyperbaric exposure will affect fluid regulation in the body

Objectives:

– To investigate the presence of cerebrospinal biochemical markers in blood during
prolonged hyperbaric exposure

– To investigate changes in the quantity of cerebrospinal biochemical markers in blood
during decompression after prolonged hyperbaric exposure

– To investigate the presence of inflammatory markers in blood during prolonged hyperbaric
exposure

– To investigate changes in the quantity of inflammatory markers in blood during
decompression after prolonged hyperbaric exposure

– To investigate if prolonged hyperbaric exposure alters fluid balance in the body
