Abstract

A computer system comprising a control program stored in a memory recommends an intravenous device for infusion therapy based on input entered by a user. The control program includes an execution program for interacting with the user to elicit responses and to provide output to the user. The user inputs parameters to the prompts of the execution program to provide the control program with information regarding the infusion and the patient. The control program further includes a logic engine which applies rules to user entered parameters to determine additional infusion characteristics and to thereby weigh various intravenous devices. Based on the assigned weights, the logic engine returns with a recommended intravenous device which is then displayed by the execution program to the user.
