Dave:

    I'm not too sure of any longterm problems, but I would imagine that
an immediate problem from
red blood cell rigidity is hypertension.  The increased work your heart
has to
do in this situation may increase nitrogen uptake.  As well, the reduced
blood
flow in your circulatory system due to the hypertension may inhibit
off-gassing from poorly circulated regions.  Anyone agree/disagree?
