What component is used over the survivor's upper arms/chest once all patient restraint straps are secured?

The chest pad is specifically designed to be placed over a survivor's upper arms and chest after patient restraint straps have been fastened. Its primary function is to add an extra layer of security and comfort, ensuring that the survivor is held securely in place while minimizing the risk of movement or injury.

The chest pad typically serves as a protective barrier, distributing pressure evenly across the chest, which can help prevent discomfort during transport. This component is also important for maintaining the safety and effectiveness of the rescue operation by enabling rescuers to manage the survivor more effectively.

The other terms listed, such as shoulder strap, upper body harness, and rescue harness, refer to different components or systems used in various contexts of rescue operations. However, in the scenario where restraint straps are already secured, the addition of a chest pad becomes crucial for final stabilization and securing of the survivor.
