Modern CPR training insists yiu have to announce what the fuck you’re doing because people will universally get the wrong idea.
You have no modesty when you’re dying- the underwire in a bra interferes with AEDs working, and the pads have to be on skin. For compressions you need to see where you are so you are, so the clothes come off.
It’s standard to drill that in, precise cause it has happened.
Hell. We’ve heard anecdotes of cops coming in and macing people giving CPR. People frequently assume the worst and act on it.
