The CPR Resuscitator Mask can be used on adults, children and infants. The clear plastic mask allows the rescuer to properly position the mask and monitor the victim, while the head straps will ensure that the mask does not move during CPR. The one-way valve prevents the passage of liquids and secretions. A soft, pliable bladder facilitates a proper seal. The mask maybe cleaned and reused but the valve is for single use only. These masks are latex free and come in a convenient easy to grab case.
