Fits right in to when I was an EMT. I get called to see one you because of your chest pains and after hooking up the 12 lead heart monitor and finding evidence of an ongoing heart attack, I turn on the radio to setup communications with the hospital and find it blocked, and when I key the mike to check, it messes up the heart traces really bad too. No problem, in a few minutes - one less opinion in the margin discussion. Okay, so it wasn't one of you, at least not one I knew, but a brief time it was a very impressive opinion.

Regards, Dave Garnier PS: In an ICU room you can have many pieces of medical electronics connected to the patient, all of these devices may meet their repective requirements under 60601-1-2 and 2-x sub-requirements but still interfere with each other. Having said that, there are some imaging or monitoring technologies that have difficulties playing nicely with each other. Gentlemen, when you see your loved one go under a product you cert'ed and audited over the years, you gain a whole different perspective of your job!

They do have margin built-in, but you won't get many to admit it, because it sounds bad, politically. Also, manufacturers can only take advantage of it if they can use the 80-80 rule (which allows a small percentage of non-compliant product to be shipped). Interference that matters results in complaints to authorities. If no-one complains, it can't matter, can it? So it makes economic and practical sense to set the limits so that there is a small but manageable level of complaint. Few will admit that this is what is done, but, whether intentional or not, it IS what happens in many cases. If there are never any complaints, the limit is set too low, maybe a lot too low, isn't it? So the 'margin' is between the actual limit (resulting in, say, 10 complaints a year) and that higher limit (resulting in, say, 50 complaints a year) that would cause the authorities to demand its reduction. -- OOO - Own Opinions Only.
