A resuscitator with a rigid top plate, a rigid bottom plate and a rigid bottom plenum assembly. The top plate is hingeldy joined at its forward end to the bottom plate. A flexible accordion member is located between the top plate and the bottom assembly forming a standard air pump. When a person pushes down on the top plate, air is forced out of and outflow tube located on the top plate. An internal spring returns the top plate to its original position and in doing so causes air to be drawn into the plenum assembly. A top plate travel limiting member, such as a cord, includes a plurality of spaced protuberances that act as restraining members that can be retained under a slot in the side of the plenum assembly thereby adjusting the travel distance of the accordion member and controlling the resulting volume of air output to a patient being resuscitated. |
