## Abstract

A medical pump for delivering medicament through an IV line to a patient may provide for awareness of the operator and operator authority limiting access by any individual to particular tasks of procedure review, pump programming, pump loading, patient set up, pump operation, and the like associated with the treatment provided by the medical pump. Identifying the operator allows the assignment of particular authority levels to the operators to ensure proper operation of the medical pump, and/or proper operators have made the necessary review to perform the necessary set up of the medical pump facilitating collaborative healthcare delivery. A record of operator intervention and authority levels may be logged to permit an automatic checklist process by the medical pump. Authentication process and pump operation parameters can be communicated through Near Field Communication (NFC).
