What Is the Recommended Action for AED Use When a Patient Is Wearing Jewelry? Move It, Don't Remove It

The recommended action is to leave the jewelry on and place the AED pads at least 1 inch (2.5 cm) away from metal, moving a necklace, chain, or piercing aside if it blocks optimal pad placement. Do not waste time removing rings, watches, or earrings, and never delay a shock to take jewelry off. Metal does not attract the current, and modern AEDs analyze rhythm and deliver therapy through the pads regardless of nearby metal. Rescuer speed and correct pad-to-skin contact matter far more than what the patient is wearing.

Mechanism: why AEDs care about contact, not conductors

An automated external defibrillator works by passing a controlled current between two adhesive pads on the chest. The current must travel through the heart muscle to depolarize a critical mass of cells at once. What determines success is the impedance of the path, which is dominated by skin contact and lung tissue, not by a gold chain lying on the surface. A metal necklace touching the skin creates a low-resistance shortcut across the chest surface. That shortcut can divert some current away from the heart and can cause superficial burns at the contact points, but it does not change the underlying rhythm or make the shock ineffective in the way most people imagine.

The deeper reason jewelry is a minor issue is that AED pads are engineered to tolerate imperfect conditions. They use conductive hydrogel, they are sized for adult chests, and the device measures impedance before and during the shock. If impedance is out of range, the AED prompts the rescuer to check pad contact. Modern devices also analyze the ECG through the pads; a piece of metal resting on the skin between the pads can add electrical noise, but it cannot mimic a shockable rhythm or block detection. The clinical priority is always the same: get the pads on, let the device analyze, and deliver a shock if advised.

There is a real physics caveat. Metal heats when current passes through it, and that is why the pads should not sit directly on top of a chain or a large piercing. The heat is localized and typically superficial, but it is avoidable. The fix is simple: slide the metal aside or cut a thin chain, place the pad on clean, dry skin, and continue. A bright red flag: never place a pad over a metal implant or a medication patch, and never let a necklace bridge the two pads. That bridge is the one scenario where surface metal could meaningfully shunt current.

Plain language: the AED is looking for a good connection to the heart, and a necklace sitting on the skin is a distraction, not a barrier.

Quantified context: how much jewelry actually matters

The numbers here are reassuring. Defibrillation success depends on delivering enough current density to the myocardium, and the pad-to-heart distance is roughly 4 to 6 inches in an adult. A necklace chain adds a millimeter-scale conductive layer on the skin surface. Its effect on transthoracic impedance is small compared with the 25 to 50 ohm range that AEDs handle routinely. Pads placed on clean, dry skin typically produce impedance in the range the device expects; the device then adjusts its output to compensate.

Time is the variable that actually changes outcomes. Every minute without defibrillation after a shockable rhythm begins reduces survival by roughly 7 to 10 percent per minute in the out-of-hospital setting. That single fact dominates every jewelry decision. Removing a ring takes seconds; removing a tight necklace or a cluster of piercings can take a minute or more, and that minute costs more lives than any theoretical current diversion. The AED's own prompts are designed around speed: attach pads, clear the patient, press shock. Jewelry removal is not in that sequence for a reason.

The one place numbers matter is pad spacing. AED manufacturers generally specify that pads should be at least 1 inch apart and not touching each other, and the anterolateral and anteroposterior placements both require skin contact. A large metal necklace can physically occupy the space where a pad needs to go. In that case, the metal is an obstacle to placement, not an electrical hazard, and the correct move is to push it aside. If it will not move and it covers the intended pad site, cut it. A thin chain cuts in seconds with trauma shears.

Edge cases: piercings, implants, and wet chests

Piercings are the most common jewelry question in practice, and the answer splits by location. Earrings, eyebrow rings, and nose studs are far from the pad sites and require no action. Nipple piercings sit near the anterolateral pad position in some placements; the usual workaround is to shift the pad slightly laterally or use the anteroposterior placement, which puts one pad on the front and one on the back. A pad should never be pressed directly onto metal jewelry, because the hydrogel-to-metal contact is poor and the metal can heat.

Implanted devices are a different category with a clear rule. Do not place an AED pad directly over an implanted pacemaker or ICD generator. Keep pads at least 1 inch away from the device, and use an alternative pad position if needed. This is a device-interference issue, not a jewelry issue, but rescuers often conflate the two. A pacemaker generator is a metal can under the skin of the upper chest; a necklace is metal on the skin. Both are moved aside, but only the implant has a formal spacing recommendation.

Wet chests, hair, and medication patches create more impedance problems than jewelry ever will. Dry the chest briskly if it is wet, clip dense chest hair if pads will not adhere, and remove transdermal patches from the pad site. A bulleted set of red flags is worth memorizing:

Never delay a shock to remove jewelry; move it or cut it only if it blocks pad placement. Do not place a pad directly over a necklace, chain, or large piercing. Never place a pad over an implanted pacemaker or ICD generator; keep 1 inch of clearance. Remove medication patches from the pad site and wipe the skin. Dry a wet chest before applying pads; water on the skin can bridge the pads. If a chain bridges both pad positions, cut it before shocking.

Misconceptions: the myths that cost seconds

The most persistent myth is that metal jewelry attracts lightning-like current and will electrocute the rescuer. It will not. The AED delivers current between its own two pads, and the rescuer is not part of that circuit when everyone is clear. The "clear" command exists so no one touches the patient during analysis and shock, not because jewelry radiates energy. A rescuer wearing a metal watch or ring is not at risk from a properly used AED.

A second myth is that all jewelry must come off before pads go on. That advice appears in some lay training materials as a simplification, and it gets over-applied. The accurate instruction is to expose the chest and ensure pads contact skin. If a necklace lies where a pad must go, move or cut it; if it does not, leave it. Rings, watches, bracelets, and earrings almost never interfere with chest pad placement, so removing them is optional and should never precede defibrillation.

The counterintuitive professional caveat is that over-preparing the chest can be worse than leaving jewelry alone. Aggressive scrubbing, alcohol wipes, and prolonged hair clipping all delay the shock and can irritate skin without improving impedance. The AED's own impedance check and "check pads" prompt are the feedback loop; trust them. If the device says check pads, fix contact, and that may mean sliding a chain aside, but it rarely means a full jewelry removal.

Practical actions: what to do in order

The sequence is short and should be rehearsed. First, expose the chest and look at where the pads will go. Second, apply pads to clean, dry skin; if a chain or large piercing sits exactly where a pad belongs, slide it aside with a gloved hand or cut a thin chain with trauma shears. Third, let the AED analyze and follow its prompts. Fourth, clear everyone and press shock when advised, then resume compressions immediately.

Thresholds worth remembering: keep pads at least 1 inch apart and at least 1 inch from an implanted device generator; do not place a pad on metal; do not delay a shock for any jewelry removal. If the AED prompts "check pads," fix adhesion and contact first, and only then consider whether metal is the cause. If a chain bridges the two pad positions, cut it before the shock. These rules reconcile the competing advice in lay and professional materials: expose the chest, ensure skin contact, avoid direct pad-on-metal contact, and never let preparation outrank defibrillation.

The rescuers' hands should be doing CPR or pad placement, not unfastening clasps. A ring left on a finger has no bearing on transthoracic current. A watch left on a wrist has no bearing on pad adhesion. The only jewelry that matters is the piece physically occupying a pad site or bridging the two pads, and both are solved in under 20 seconds.

Limitations and what this guidance cannot cover

This guidance reflects stable principles of defibrillation and pad placement, not a specific manufacturer's manual. Device prompts, pad designs, and impedance thresholds vary by model, and the AED's own voice prompts take precedence over any general rule. Pediatric pad placement, pregnancy, and traumatic arrest each have separate considerations not addressed here. The evidence base for jewelry-specific interference is thin and largely drawn from case reports and electrical safety principles, so the recommendations above are conservative and mechanism-based rather than trial-derived.
