Thankyou very much for your replies, they are most helpful.I can only envisage that the situation develops when a drug is added to a solution greater than 50/60mls and a volumetric pump is required.Some of our syringe pumps will at least indicate that they are about to go into KVO mode,I'm not sure if the volumetrics can do that.KVO mode ,I've always thought, was more suited to a busy (understaffed) ward situation where nurses would welcome the flexibility it offers.
