Should you remove nipple piercings before you use an aed?

No: The most important predictor of success when using an AED is how quickly (after cardiac arrest) the shock is delivered. When placed appropiately, the pads of an AED should not come in contact with a nipple ring but regardless, the time spent removing the rings is better spent applying the pads and delivering what may be a life saving shock.

Yes: Piercing will act as a conductor.

AED: If a person needs to have emergency cardioversion for a life threatening ventricular arrhythmia, you don't waste time with pierced nipple rings.
