[Oxygen and hydrogen dynamics in the skin of aquanauts under a prolonged hyperbaric exposure].

Polarographic measurements of the dynamics of partial pressures and diffusion parameters of O2 and H2 in the skin of aquanauts during prolonged hyperbaric exposure to He-O2 breathing to 3, 3.6 mPa were performed. It was indicated that at an early exposure stage there occur the distinct changes in cutaneous oxygen profiles manifested as: increased rate of local blood flow, decreased intensity of O2 utilization and due to this as elevated cutaneous PO2 levels.
