Here is a complete breakdown of ZOLL defibrillator pad placement, directly from ZOLL's official guidance and aligned with AHA recommendations.
ZOLL Pad Positions - Adults
There are two accepted configurations:
1. Anterior-Lateral (most common)
| Pad | Location |
|---|---|
| Sternum (right) | To the right of the sternum (patient's right), just below the clavicle, above the right nipple |
| Lateral (left/apex) | Just below and to the left of the left nipple, along the anterior-axillary line (under the breast on females) |
2. Anterior-Posterior (front-back)
| Pad | Location |
|---|---|
| Posterior (back) | To the left of the spine, just below the scapula, at heart level |
| Anterior (front) | Over the cardiac apex - between the midline of the chest and nipple (male), or under the breast (female) |
Pediatric Pads
ZOLL pediatric electrodes are designed specifically for anterior-posterior positioning:
- Back pad: Along the center of the spine
- Front pad: Over the cardiac apex, between the midline and nipple
For very small children where the pads may overlap, use the A/P configuration only.
Key Tips
- Follow the diagram printed on the pad packaging - each ZOLL electrode has a placement diagram on it
- For ZOLL CPR Stat-Padz: Red = posterior ("red to the bed"), Purple = anterior
- The purple pad is the positive lead - positioning it closest to the heart with minimal impedance optimizes defibrillation success and pacing capture
- Avoid placing pads over implanted devices (pacemakers, ICDs) - move at least 1 inch away
- Ensure skin is dry and free of excessive hair for good contact
Both anterior-lateral and anterior-posterior positions are considered acceptable by the AHA for adult defibrillation.
