3. 1443 mandates flow rates for continuous flow systems. Newer systems
utilize "pulsed" flows. Manufacturers claim greatly reduced oxygen
utilization using these systems, and even lesser use when these "pulsed"
systems are used with an Oxymizer type of cannula. As far as I can tell
these claims have never been objectively and openly verified by any
peer-reviewed research.

I looked at advertisements from several vendors, and the Oxymiser is
always presented for use with _constant flow_ systems, not pulse
systems. In fact, the EDS system (and probably the others, but I'm not
familiar with them) requires a low volume cannula to work properly: an
"Oxymiser" or even long tubing from the unit with cause it to
malfunction. Take a look at the Mountain High web site:
