In my humble opinion, anyone who suggests that an item of in-service electromedical equipment doesn't need to be "looked at" by biomed for at least four years is talking out of his/her ****! Not only that, but surely such a sloppy approach to the concept of "duty of care" would be, in fact, indefensible in law?

We have a Pulsion Picco monitor which doesnt require servicing.
Says who ... the sales rep? What do your biomeds say, Quinny? If you have doubts, why not raise a Work Order whenever you think it needs checking out? I seem to recall that (at one place I know) these things were returned to the manufacturer when they got dropped. OK, but what about electrical safety checks?
