Abstract

In rabbits, rats and mice, the delays of maximum of the brain oxygenation curves in respect to the maximum pressure curves were found to be 47.4 +/- 5.5 s; 32.6 +/- 2.9 s; and 26.4 +/- 2.0 s, resp. The data obtained shows the brain oxygenation monitoring to help to predict the nitrogen tension dynamics in the "fast" tissues during simulation of free surfacing.
