A mouth-to-barrier device in CPR is a resuscitation tool that facilitates rescue breathing while minimizing the risk of disease transmission between the rescuer and the victim. It typically consists of a plastic barrier or mask that covers the victim's mouth and has a one-way valve to allow air to be delivered into the lungs without the rescuer's breath mixing with the victim's. This device is especially useful in situations where the rescuer is concerned about hygiene or safety. Using a mouth-to-barrier device can enhance the effectiveness and safety of providing CPR.
