Sažetak
The effect of hyperbaric oxygen on peripheral circulation was examined on the lower Limbs of healthy persons, indirectly, using bilateral impedance rheography. In the experimental group the rheogram was recorded in control conditions before and after exposure to hyperbaric atmosphere, during air breathing, and in different phases of oxygen breathing under a pressure of 2.8 bars. In the control group the rheogram was recorded in the same time intervals while the subjects breathed air under normal atmospheric pressure. The results show that while the subject breathed hyperbaric oxygen the average pulse frequency, depending on the phase of examination, decreased in average by 13-15%, pulse volume by 6-8%, and volume perfusion by 17-19%. In the control group these parameters varied to a much lesser degree, irregularly and mainly in the opposite direction. The volume perfusion fall in the experimental group was primarily caused by bradycardia and to a lesser extent, by a decrease in pulse volume. It remains to elucidate whether pulse volume is influenced by vasoconstriction, since the effect of vasoconstriction on brain circulation during hyperbaric oxygen breathing, has been confirmed by numerous researchers.
