The invention relates to a method for setting mutually dependent parameters (6061,62) of a microprocessor controlled medical apparatus, whereby processes (50) of the medical apparatus are operated based on these parameter settings (6061,62). The medical apparatus comprises at least a software component (20) driving a user interface (21) connected to a screen (10) and a storage unit (22) in which a set of rules is stored that defines the relationship between mutually dependent parameter settings (6061,62), whereby the medical apparatus further comprises means for manual selection and amendment of the parameter settings (606162) by an operator, the method comprising:- displaying on the screen (10) a set of at least two mutually dependent parameter settings (6061,62)- displaying on the screen (10) a range of possible values for at least one parameter setting (606162), whereby at least one of the limiters of the range of possible values is mutable and is automatically determined based on the current parameter settings- adjusting a parameter setting (606162) upon manual selection by an operator- automatically determining and displaying the value of at least one parameter setting (606162) depending on the parameter setting (606162) that is adjusted by the operator, whereby the determination of said dependent parameter setting (606162) is at least based on the stored relationships between parameter settings (606162)- implementing the set of amended parameter settings (606162) by actuating a batch setting acceptance operation and- operating the processes (50) of the medical apparatus based on the set of amended parameter settings (606162).
