A medical device includes a network interface, a processor unit, a memory unit, an actuator physiologically acting on a patient and/or a sensor interface detecting a sensor signal indicative of a patient physiological parameter. The network interface receives a sender network identity data message, a sender authorization level and a sender change request to change an actuator operating parameter and/or a predefined alarm detection value. The memory unit provides a predefined minimum authorization level. The processor unit determines an actual authorization of the sender to change the operating parameter and/or to predefine a value on the basis of the sender authorization level and of the predefined minimum authorization level as well as to change the operating parameter as a function of the result of the determination and/or to perform a detection of an alarm generation state as a function of the indicated predefined value and of the sensor signal.
