An AP system comprises a BGM, CGM, insulin pump, and controller. The blood glucose measurement from the BGM is used periodically for CGM calibration to provide the most accurate estimates. The AP controller receives continuous glucose measurements from the CGM and performs a series of mathematical calculations. Based on these calculations, the controller communicates delivery instructions to the insulin pump. Communication standards for the CGM and insulin pump will allow consistent device communication with the controller, and device information may be extended to wider interoperability platforms for the purposes of telemonitoring and review on electronic health record/personal health record systems. EHR, electronic health record; PHR, personal health record.
