A medical monitoring device includes a system for monitoring and recording physiological parameters of a patient. The monitored physiological parameters are compared by a comparator with a predetermined threshold or an alarm limitassociated with the respective physiological parameter, the presence of an event being detected, if a physiological parameter exceeds the associated threshold or the associated alarm limit for a predetermined period of time, depending on an operation mode set by a user. If the presence of an event is detected, the fact that an event was detected, the parameter value which caused the event and, optionally, further recorded parameter values as well as the respective time at which the event was detected are stored in a memory. Finally, the medical monitoring device includes a display on which a representation of the events which were stored during a predetermined, preceding period of time is produced in relation to time. The mode of representation of a respective event depends on the extent to which the parameter causing the event has exceeded the associated threshold or the associated alarm limit. Alternatively or additionally, the representation also contains a display showing the respective thresholds during said predetermined period of time, in relation to time.
