What is a breathing barrier used for?

A breathing barrier is a protective device used in emergency situations to facilitate rescue breaths while preventing direct contact between the rescuer and the victim. It typically features a one-way valve that allows air to enter the victim's lungs but prevents exhaled air and fluids from coming back to the rescuer. This helps reduce the risk of transmission of Infectious Diseases during mouth-to-mouth resuscitation. Breathing barriers are commonly included in first aid kits and are essential for CPR training and practice.
