Subject: Rebreathers: changing diluents for decompression
From: dwilkins@ci*.co*.co*.uk* (David Wilkins)

When diving trimix on open-circuit scuba, it is standard practice to use 
nitrox(es) and oxygen for decompression, as getting off helium as soon 
as possible gives a noticably reduced decompression duration.

Running a few tables, it seems as this would also be a significant 
advantage using a rebreather, ie do the main part of the dive on a 
trimix (or heliox) diluent, then switch diluent for the decompression to 
a nitrox. 

Are any of the (forthcoming) rebreathers capable of handling this? Any 
other thoughts on this matter would also be welcomed.
