Airflow Measurement

[CONATSER.STEVEN_D@FORUM.VA.GOV]

   Ken:  Talk with the folks at your pulmonary (respiratory) department, to
get advice about the respirometers they use to measure adequacy of lung
performance.
   I've acquired a "Wright Respirometer", Model "Mark 8" which is ideal for
measuring minute volume measurements.  It comes with a couple of adaptors
to allow direct hookup of the respirometer to different tube diameters.  I
attached a hose to our (Pulmonex) Xenon system's exhaust port, and the
Mark 8 fits snugly into the exhaust port-hose.
   Please contact me at (313) 576-1000, ext 3595 if you have further
questions.  Steve Conatser, RSO, VA Medical Center, Detroit.
