I like to hang 0.9% NS to gravity when possible because I always thought that the fluids would stop infusing if the IV site blows. A co-worker of mine disagrees and said that IV fluids hung to gravity would continue to flow and infiltrate if an IV site blows.
Because of the way they deal with water, glycol and silicone based fluids are NOT compatible with each other. Never mix the 2 types of fluid. Only add DOT 5 silicone brake fluid to a completely dry system or a vehicle that already has DOT 5 in it.
