Nuisance alarm reductions in a physiological monitor

A method for controlling an alarm in a medical diagnostic apparatus, watching this device a measured value, said method comprising: - measuring a value of a physiological parameter, - the establishment of a dynamic threshold value, - the establishment of a value condition from a combination of said measured value and said dynamic threshold value, - triggering an alarm when the corresponding threshold value to a condition exceeds a predetermined level, - monitoring said alarm when a measured value said physiological parameter is outside a fixed range, - the establishment of an upper threshold value set and a lower threshold value set, wherein said threshold values ​​set define said fixed range, - determining a period of time which said measured value is outside this interval set, - determining a measure of the amount by which said intervalofijado is exceeded by said value during that period, and - triggering the alarm when a combination of that period time and it exceeds a second predetermined level.
