Exact steps dependent on whether blood will be<unk> d via an apheresis machine and specific model
Apheresis may require large-bore central venous catheter (e.g. HD line or pheresis catheter)
If no apheresis machine available:
Place at least two peripheral IVs
Slowly remove 5-20mL of patient's blood
Replace phlebotomized blood with warmed RBCs (or saline/albumin/plasma) in equal or greater amounts
Repeat prior steps until desired amount transfused
