Our Emergency CPR mask is designed with the rescuer/first responder in mind. Sized for use on adults and children, our clear mask allows the rescuer to position it properly and monitor the victim. Our soft, pliable bladder ensures a secure seal. Mask can be used with the standard one-way valve for rescue or with our CPR Practi-VALVES during CPR manikin training. Mask may be cleaned and reused but only for training purposes. Dispose of mask and valve after patient use..
