DetailsThis CPR kit is packaged in a compact, hard shelled, pocket-sized carrying case that features a patented one-way valve with filter. The CPR mask, which has a transparent dome, prevents mouth-to-mouth contact. It has a leak-proof seal, and the re-inflected contoured soft vinyl cuff shapes easily to adult, child, and infant facial contours. The mask, which is ready to use with no need to assemble valve and filter, comes with gloves and a wipe. And the case can be customized in volume.
