Surely someone who just works on renal machine should have to have further understanding of other equipment,
Likewise electronics need further understanding of anaesthesia or renal.
I think the comment that certain engineers etc. will not cope with working on patient connected machines is irrelevant, as what everyone does could have an immediate or detrimental effect to the patient hence the need for registration in the first place.
Therefore every one promotes there own corner but broader understanding should not be a level of how much you know in your own field, but your effectiveness at functioning and be accepted in one of the other fields.
