What is a Barrier Device?

Barrier devices, such as face shields or masks with one-way valves, are used during resuscitation to protect both the rescuer and the casualty from potential infection transmission. These devices provide a physical barrier while allowing air to pass through during mouth-to-mouth resuscitation. Using barrier devices is especially important when there is a risk of contact with body fluids.

They are essential components of first aid kits and should be readily available in emergencies to ensure safe and effective artificial respiration .

Using a Barrier Device

Place the barrier device over the casualty’s mouth and nose.
Ensure a good seal to prevent air leakage.
Perform rescue breaths through the device according to CPR guidelines.
Clean or dispose of the barrier device according to hygiene protocols after use.

Takeaway to Remember

Barrier devices, such as face shields and pocket masks, are used during CPR to protect both the rescuer and the casualty from potential infections. These devices create a barrier between the rescuer's mouth and the casualty's mouth and nose.
