The Laerdal Little Junior chest skin serves as a direct factory replacement overlay for the Little Junior CPR training manikin series. This realistic chest skin layer features correct anatomical landmarks required for accurate physical assessment, proper hand placement during chest compressions, and automated external defibrillator (AED) pad placement exercises. Upgrading or replacing a worn, stained, or damaged torso skin ensures that clinical simulation labs maintain a professional, hygienic environment while supporting basic life support (BLS) training programs.
