This kit includes 2 CPR masks — one for adult patients and one for children, and one that is specially sized for infants. Constructed of clear materials, our masks help rescuers ensure proper positioning, and allow them to monitor the patient while providing care. Masks come equipped with elastic, latex-free head straps, as well as one-way valves with built-in filters and oxygen inlets, and bladder inflation ensures a proper seal. A soft nylon case with belt loop and belt clip is included, making our CPR masks convenient to carry.
