May I askÂ informationÂ what publications or articles that state PIVs size can use ga. 22 for blood transfusion( especially RBC) by gravity infusion. I read some articles written on this, but forgot where I can refer this time for reference. Other Nurses are still very hesitant to run the RBC infusion to ga 22 size IV access. Patient has no other good veins to fit the ga 20 as most nurses preferred. Thank you so much!
