What is the purpose of using a barrier device during CPR?

Barrier devices used during CPR protect both the rescuer and the patient by limiting exposure to saliva, blood, and other bodily fluids while providing rescue breaths. They create a seal and often include a one-way valve, allowing breaths to be delivered without mouth-to-mouth contact and reducing the risk of disease transmission. This safety feature is the main purpose, whereas options like camouflage, making breaths louder, or preventing movement are not related to how CPR is performed or safety during ventilation.
