Abstract: A compact lightweight resuscitator system for use by paramedics and rescue personnel is described. The basic apparatus, including a full cylinder of oxygen, weighs about fourteen pounds. It comprises a single channel aluminum frame on which is fastened an oxygen cylinder, a regulator and low pressure manifold, a demand valve with three sizes of resuscitator masks, a regulated and indicated flow inhalation circuit, a set of airways, and a variable rate aspirator with hose and catheter. Additional accessories, which bring the weight to sixteen pounds, include a humidifier for the inhalation circuit, another line and coupler for attaching a second oxygen cylinder and an IV stand. The resultant system enables all standard procedures to be used by paramedic personnel and rescue technicians but is greatly reduced in size and weight.
