CPR Micro Shield The CPR MICROSHIELD was designed to meet two critical specifications; protect the rescuer and allow the rescuer to perform proper CPR according to the established guidelines and procedures * Our patented one-way valve and single piece design assures the rescuer that our barrier will not leak or ever fall apart during CPR * At the heart of the CPR MICROSHIELD is a patented valve that is always closed until the rescuer exhales * The valve opens to provide a low resistance airway and closes immediately when the rescuer finishes each breath * Designed to complement not complicate the specific techniques known as CPR * True Mouth to Mouth Seal is achieved: Our sealing method is identical to the method taught in CPR classes thus avoiding complicated hand seal methods which pull the rescuer from the all important learned technique * This also allows the rescuer to perform an effective head-tilt chin-lift maneuver * Airway Enhancement: The bite block/airway tunnel inserted into the patient's mouth assists the rescuer in maintaining an open airway when performing the head-tilt chin-lift maneuver * Clear Barrier allows the rescuer to observe signs of obstructions fluids present and lip color while performing CPR * Single Piece Design: Although the CPR MICROSHIELD consists of several component parts all are sealed together to provide a product without leaks where the bite block and the barrier meet * Latex-free
