Abstract: This is a device for resuscitation of asphyxiated or semi asphyxiated patients. It is used primarily by emergency rescue and ambulance personnel. It is designed to supplement equipment already in use and is not intended to replace other equipment. It comprises manually operable mechanical equipment to replace the use of a medic's hand, presently used to squeeze and release a plastic air bag (10) which in turn alternately forces air or oxygen into the lungs of the patient and releases carbon dioxide and other waste gases from the lungs of the patient. The resuscitation device holds the plastic bag between a stationary mechanical upper hand (36) and a vertically moveable mechanical lower hand (56). The vertical movement of the lower hand is sustained by a pivotable lever (70) which is manually operated by rescue personnel.
