Abstract

Techniques for integrating messages from a medical care devices used to monitor or treat a patient include receiving association data. The association data indicates an association between a particular patient and one portable communication device assigned to one primary medical caregiver. The association data also indicates multiple associations between the patient and corresponding medical data generators. A medical data generator provides medical data to support an alert that indicates attention is desired from a medical caregiver. The medical data generators direct their data to diverse destinations. If an alert is issued based on any of the medical data generators, the portable communication device is determined based on the alert and the association data, a caregiver message is generated based on the alert, and the caregiver message is sent to the portable communication device. These techniques allow alerts from multiple medical devices to be integrated onto a single portable communication device.
