I'm writing:

I don't want to put words in Peter's mouth but I believe what he is saying
is that the breathing loop must be able to meet the divers respiratory
minute volume plus 10%.  To do this the counter lung must have a large 
enough volume and the loop breathing resistance must not overly inhibit 
the breathing rate.  I don't think he's saying that the flow rate must be 
large enough in volume to meet the minute volume plus 10%.  If it was
why use a breather?

Is this what you're saying Peter?
