I have never had a proper explanation for this.
The purpose of using tables and observing ascent rate and stops is to control the outgassing of nitrogen. That is, we are controlling the partial pressures differential of nitrogen. When using pure oxygen (transporting victim to med facilities; final 10' deco stop, say), this pressure differential is suddenly up to maximum. Why then are nitrogen bubbles not formed? Or are they?
