The Lifesaver CPR Mask is designed to assist first responders with reliable performance necessary to providing effective mouth-to-mouth resuscitation while protecting users from the transmission of fluids or other contaminants. The replaceable, one-way valve includes a biological filter for maximum security. When removed from its protective hard plastic case, the mask automatically deploys to its ready position. EMI's mask will easily form a high-quality seal on an adult or child's face, even when exposed to temperature extremes. The standard kit includes a head strap, an oxygen inlet valve, a pair of nitrile gloves and two antimicrobial hand wipes, while the Plus kit features a convenient holster for portability of all items.
