This old concept derived from the size of the internal lumen of
peripheral catheters. Now technology allows for thin walls meaning
larger lumens, so no need to use a garden hose for blood anymore.

Tamara,
There are several entries in the venous archives that reference the fact that 22g caths are ok to infuse blood products through. http://www.mail-archive.com/cgi-bin/htsearch?method=and&format=short&config=venous_mailsrv1_ohsu_edu&restrict=&exclude=&words=blood+administration+22g
The old info that we all learned in nursing school about using anything smaller than a 20g will lyse the cells is not true. A co-worker once pointed out that our cells make it through our capillaries without lysing, so certainly cells can make it through a 22g catheter. I thought that made a lot of sense.
