The Innosonian America-S13401 Chest Compression Pad is an essential OEM replacement component engineered specifically for the internal sternum assembly of the Brayden Advanced (LED) Adult CPR training manikin. Positioned directly over the compression sensor and spring mechanism, this durable pad cushions repeated high-impact chest compressions while evenly distributing force across the internal sensor array. By maintaining proper contact and surface alignment between the manikin's chest skin and internal electronics, it ensures consistent depth sensing, protects sensitive LED lighting modules from direct impact wear, and maintains realistic tactile feedback during BLS and ACLS CPR training.
