Subject: Surface 02 to Altitude
Hi all,

I have a recent concern about driving to altitude after dives 
generally the ones to the 100 mark +-. and bt of 60-80 min.
I use a ppO2 1.4 on these dives and do slow ascents and
Deco on 100% at pp02 1.6

I will referance Tables and round up the EAD's and then for Deco I will
also go to the next greater time/depth deco factors.

Now when coupled with drysuit I feel really great after the dives.
But when I dive wet or my cheap suit leaks,   well the feeling
is just not the same. 

Problems I face when driving back to Atlanta after these dives
are a bit of the sleepys, or at times old injuries are kinda
remembered.

This only happens when I have to make an imediate return to Atlanta.

I am thinking that after the surface Deco and all the gear is stowed,
to just get on 02 and reinstate a deco while driving to futher enhance
the off gasing of N2.

The 70' +- dives do not give me this problem and I do compensate my
Decos based on the Dry /Wet Factors and for depth considerations.

Also I am wondering what are accecptable  Surface Breathing times for 02?


Thanks
