Blood Transfusion and Infusion Pump use - Revisited

I was browsing through Allnurses when I came across a closed topic on blood transfusion using infusion pumps.

I was surprised to read the number of persons who use infusion pumps for blood transfusion. Though it would appear on the surface that this should be fine a quick read of all the manuals for the pumps I found state that they should NOT be used. The issue is NOT with the drop counter mechanism but with the actual pumping device, the peristaltic pump mechanism. And there are a few articles such as Infusion pumps and red blood cell damage in transfusion therapy: an integrative revision of the academic literature

The IVAC manual does say i can be used for blood products, which is strange considering it does use a peristaltic pumping mechanism like most other pump whose manuals have blood as a contraindication for use.

If i am not mistaken gravity is recommended or a pressure infuser if the rate needs to be higher.

Would be interested in what scientific data others have found, and what various user manuls from manufacturers such as Baxter, Medfusion, B Braun, Fresenius, Graseby etc say.
