Characterization of Flow in Intravenous Infusion Systems


The pressure-flow (P-F) relationship for intravenous infusion systems is found to be nonlinear, and may be expressed by the mathematical model P = RLF + RTF2. The parameters RL and RT both show linear increase with tubing length. Devices have been identified with an isolated effect on RL (5 ¿fiter) or on RT (check valve). The total RL and RT of an infusion… (More)
