Bring the bounce back to your Little Anne with the Compression Spring 20510—the factory‑calibrated spring that powers realistic chest recoil, helping students master proper CPR rhythm and depth.
Why replace the spring?
After thousands of compressions, the original spring can fatigue, slowing chest rebound and skewing depth cues. Installing this OEM replacement ensures every push meets American Heart Association (AHA) standards and every release delivers the full recoil that promotes effective blood‑flow simulation.
