Abstract
A resuscitator device for providing a physical shield between the rescuer and a victim requiring mouth-to-mouth resuscitation.

Grooves are formed in the victim's side of the sheet to provide air pathways to the outside for air exhaled by the victim. A patch of an irregular non-smooth surface is also formed on the victim's side of the sheet to preve…
