I have been thinking about some deep diving in Lake Tahoe, which is at an altitude of approx. 6000'. I know that decompression profiles are significantly changed by the reduced atmospheric pressure. What I have been wondering is how depth limits based on PO2s are affected. At first thought, I would think that one could breathe a given mix at a deeper depth than at sea level, since the absolute pressure at any given depth is less than at sea level. E.g., a decompressing diver could go on O2 at something like 24 ffw instead of 20 ffw and still maintain a PO2 limit of 1.6 ATA (I don't want to argue here about whether 1.6 ATAs PO2 when breathing O2 at 20 fsw is safe; this is just an example).
