Simplified approach to assessing intravenous flow characteristics in the therapeutic infusion range

It is shown that the pressure-flow (P-F) relationship in intravenous infusion systems can be simply described by the flow parameters R/sub L/ (linear-resistance) and F/sub E/ (flow nonlinearity). The relative-pressure error due to nonlinear flow is found to be insignificant in the flow range used for therapeutic intravenous infusion therapy (F>
