83 mL/hr
This is a small volume IV (usually 50 to 100 mL) that contains medication diluted in an IV solution such as normal saline or D5W.
IV piggyback
This has the same concentration as that of body fluids.
Normal Saline
When these are less than 0.9 % NaCl they are less concentrated than body fluids. (ex. 0.45% NaCl, 0.225% Nacl, 3% NaCl)
