Nearly every hospital I’ve had occasion to visit, in the past 10+ years, has had prominent signs saying in Big, Unfriendly Letters that “if you don’t turn off your cell phone when you’re within 20 miles of this building you’ll kill every patient inside and most of their visiting relatives”.
…or something like that.
The one exception (until the other day) was the hospital where my mother died a couple of years ago - no such sign, and we siblings had our cell phones on - and in use - for several days while Mom was ill. We’re pretty sure we didn’t do her in.
The other day, Typo Knig was in for surgery at a place near our house. I looked for such signs at the hospital entrance, and didn’t see them, so I left my phone on (Typo told me they used to have the signs, but had taken 'em down). Wasn’t until after he’d been wheeled away and was in surgery for most of an hour that I saw such a sign, displayed behind the receiptionist’s desk in the surgery waiting room.
Fortunately at that point there were only two patients left in the place; I know the other patient survived and certainly Typo appears to have done so, so I don’t think I committed involuntary manslaughter.
But really - what is it about cell phones and hospital equipment? Is this another of those “use it and your gas pump will explode” myths? I once used one in the ER in California (long story but it was essential we speak with someone on the east coast) right in front of a doctor and she didn’t even blink.
