[net.space] pressure vs. breathing

cjh@CCA-UNIX@sri-unix (11/25/82)

   You \\may// have a point on the true effects of pressure on the ability
to breathe, but your analogies are way off; in particular, total pressure
in bagpipes and tubas is \not/ high (can't give you numbers, but for
comparison an organ will run 70-90 mmHg) while in artificial respiration
you're balancing your active muscles against somebody else's inactive ones.
