of the present invention these are 7 maximum allowable fluid load resulting from infusion of one medication and 8 maximum permitted concentration for each medication in step 108 the input data is processed to determine the two to four optimum concentrations low intermediate high and super high in one embodiment of the present invention the lowest concentration is the one that results in the lowest acceptable infusion rate at the lowest dose for the lowest weight patient and the highest concentration is predetermined based on published pharmacological data in such an embodiment of the present invention the intermediate concentration is then determined based on the range between the minimum and maximum dose moreover embodiments of the present invention can default to commercially available premixed concentrations whenever such premixed concentrations are available for example according to one computer based embodiment of the present invention the computer program processes the data as follows 1 low concentration is determined by the computer program as follows a first the drug information sheet built into the program to see if only one concentration is permitted for a particular drug the drug information sheet contains information related to various drugs the information can be found in standard drug texts that are well known to those skilled in the art if the answer is yes then the final low concentration equal to the only permitted concentration is displayed b next the preliminary low concentration using the following formula is calculated preliminary low concentration lowest patient weight multiplied by lowest dose.
