Made specifically for the ZOLL AED 3 Trainer, these liners help protect your reusable training electrodes from wear and tear while preserving the lifelike feel that’s essential for effective CPR and AED training.
Why do you need replacement liners for training pads?
When trainees practise peeling and placing electrode pads, they build the muscle memory and confidence they’ll need to respond quickly when it truly matters. A realistic hands-on experience helps make those actions second nature in an emergency.
Over time, worn or reused liners lose their grip, which can reduce the effectiveness of training. They may also collect bacteria from previous sessions, raising avoidable hygiene concerns in group learning environments.
Replacing liners between sessions or participants helps maintain cleanliness and consistency, ensuring every learner benefits from the same high-quality, realistic training experience.
