The Innosonian America-S16102 Head Unit is an essential OEM replacement assembly designed specifically for the Brayden Pro Adult CPR training manikin series. This complete internal and external head structure forms the anatomical base for practicing proper head-tilt, chin-lift, and jaw-thrust airway management techniques. Manufactured from high-impact, medical-grade materials, the head unit securely connects to the manikin's neck mechanism and internal breathing pathways, ensuring a tight, hygienic seal with disposable artificial lungs for realistic rescue breathing simulations.
