This CPR Mask with one-way valve is used during respiratory and cardiac emergencies as a physical barrier when administering rescuing 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, as well as an elastic headstrap. Oxygen inlet included for optional supplemental oxygen. Comes in a compact hardshell carrying case for easy carrying.
