Hello: I have been struggling with this search/research. My patron is has phrased this question a couple of ways: Why blood can't go through a pigtail to microbore tubing? Can blood be administered directly from IV pump tubing, 3 way stop-cock tubing or "pigtail" into a angio cath? Smallest bore angio cath appropriate to administer through. Any help would be appreciated.
