A system (100) is provided for processing an alert signal of a medical device associated with a patient. The alert signal comprises medical information (122) representing an alert generated by the medical device to alert a healthcare professional to a state of the patient and/or the medical device. The system obtains the alert signal (024) of the medical device (020). The system comprises an interpretation subsystem (140) which accesses an interpretation database (040). Using the interpretation database (040), the interpretation subsystem (140) generates an interpreted version (142) of the alert by using the interpretation data (044) to interpret the medical information. This interpreted version of the alert provides an explanation of the alert in a manner suitable for a non-professional caretaker of the patient. The system then generates an output signal (162) comprising said interpreted version for a mobile device to enable communicating the interpreted version of the medical information to the non-professional caretaker via the mobile device (060). As such, the non-professional caretaker is provided with information he/she can understand.
