This is our bestselling CPR mask and comes complete with head strap and O2 inlet. CPR Mask is packaged in a compact, hard shell, pocket-sized carrying case and features a patented one-way valve with filter. This mask prevents mouth-to-mouth contact with the victim's face. It has a contoured soft vinyl cuff that shapes easily to adult, child and infant facial contours. Its transparent dome allows the rescuer to check the victim's mouth for lip color and secretions. The mask is ready to use with no need to assemble valve and filter, which saves valuable time in emergencies. This CPR Mask is recognized by all major agencies. Our mask comes with gloves and a wipe, which is an advantage over most other masks in the industry.
