Tough guy, since air would likely have more O2 than trimix, there would be more CO2 produced potentially. Helium is easier to breath, so there is one way you get less CO2 (less work), and as it is less dense, the transfer out is better, and since you are theoretically diving a lower PPO2, you will get less of the effect where big concentraitons of O2 in the blood block the escape of CO2 from the tissues, a problem in deep diving. I assume that by "buildup", you mean trapped in the tissues. Anyone with good cardiovasuclar efficiency will naturally have less of a problem with this. - G On Sun, 17 Mar 1996, bill_m@wi*.co* (Bill Merrill) wrote: >Question for the group: Does anyone know if carbon dioxide buildup is more >common on air than on trimix?
