Chuck,

I have just run your scenario through Abyss.  What's the problem?

Harry.


>> I need a "staged" decompression profile for a saturation exposure at 
50 fsw on either air or 10 / 90 Nitrox.

This is for a science project that intends to place two mice at 50 fsw 
for 24 hrs. Housing is built and needs one final test which will be 
completed in the next couple of weeks.   Project will be conducted this 
summer.

Seamless deco profiles will not work because of logistics - the housing 
must be raised in stages and tended by divers throughout the 
decompression phase.
 
I can not use standard programs such as Abyss and Decom because of 
probable reciprocity failure beyond certain limits of exposure and most 
presently used saturation decompression profiles are either seamless or 
require many logistically undesirable gas switches.

I prefer to keep O2 exposure to a minimum because of the higher 
metabolism rate of the subjects (possible greater susceptability to O2 
tox & O2 radical damage) so air or bottom mix is desirable for deeper 
stops. 

I am hoping that someone with commercial experience may have access to 
such a schedule or one adaptable to this application.   

Any help or suggestions appreciated.

Thanks,  Chuck <<
