For a realistic manikin for CPR and AED training, the Prestan Adult Professional Manikin was designed. It is available in the market for individual purchases or multi-packs of four manikins which is ideal for training and seminars. The manikin features a clamshell like design that makes it easy for the user to insert a face shield or lung bag. A package of one adult manikin comes in a nylon carrying bag and measures 14" x 7" x 23" with 1 CPR monitor (with 2 AA batteries), 10 lung bags and an instruction sheet.
