The CPR Mask with one-way valve is used during Respiratory and Cardiac Emergencies as a physical barrier device when administering rescue breaths to a person. The one-way valve prevents bodily fluids and airborne pathogens from reaching the rescuer. The medical-grade thermoplastic mask has a soft inflated cuff for a leakproof seal and adds to the patient’s comfort as well as an elastic head strap allowing the rescuer to secure the mask to the patient’s face.
