Hi Trey,

sorry, but that did not quite answer my question. I guess your answer
relates to a PPO2 of 1.6, but what is the relation to lower PPO2s? Is =
it a
relation like a spike after 25/45 that is  55% ? So therefor the =
conclusion
of a spike after 100 min at 1.3 PPO2 ? Or due to the lower PPO2 a lower
reaction in the alveoles and a higher time tolerance, and therefor a =
shifted
curve for whatever time?=20

regards

Christian

The curve sharply spikes beyond 25 minutes. Most peole are such deco
