define excessive...ha.  No, I, personally,don't believe that is cause for concern.  We ventilate at 6-8 ml/kg.  Standard BV is, what, a couple liters?  A 70 kg person would get 500-600 mL by a vent.  Vd (dead space) in that person would be 1 ml/lb or 154 mL (normal anatomy).  Could that little piece of corrugated tubing really make much of a difference in the Vd?  I don't believe so.

My opinion...educated, I think.
