Abstract

In previous publications (Manil et al., 1978; 1981; Bourgain et al., 1980) the spontaneous fluctuations of the cortical tissue pressure in oxygen (Po2) in the awake rabbit were described in detail. The mean amplitude of these irregular oscillations was 5% of the normal local Po2 where 100% is defined as the value recorded in normal control conditions and 0% as the value recorded when death occurred after sustained pure nitrogen breathing. Analysis of the frequency domain demonstrates that in control conditions the power of the spectrum decreased from 0.06 to 0.5 Hz.
