That's a good comment Paul.

I've always been a fan of ECRI myself. As far back as the 1980's they published their excellent "Product Comparison System" (I can say that with some certainty as my own company at that time was a subscriber) and no doubt they have something
similar available today*. But I digress ...
I note that the original poster (our friend in Maryland) seemingly works for a government
agency. And I simply refuse to believe that the US Government doesn't have all this stuff "done and dusted". So perhaps Neil's earlier comment about "flying over" wasn't quite so trite after all.

For the penniless amongst us (
ie, not the US Government) there are a few websites where interesting information may be gathered. For instance:-
1)
Medcompare2)
IHE ... to name but two.
Meanwhile ... how many front line anaesthesia systems are currently available for purchase from new in the USA? Half a dozen? So ... why not just get them all in, and let the "tight snaggers" decide?

Failing that, simply collect up the brochures, collate relevant information in tabular form, distribute to whomever ... then stand back and wait? No. Give them ten days then set up the meeting to agree the way forward.
