The photographs show details of a portable hand-operated external cardiac compressor which when combined with a simple positive pressure respirator forms a very satisfactory portable heart/lung resuscitator. Previous compressors have required electric power or an oxygen or compressed air supply which makes them less portable, more expensive and more difficult to use correctly. Other hand-operated compressors have been designed for use in hospitals where the patient is static, e.g. in bed. Obviously resuscitation must be continued while the patient is being transported from hazardous conditions as in mines, or fires, or being taken to hospital for defibrillation. This new compressor is cheap, easy to use, cannot over-depress the sternum, and by using a double system of leverage can be used anywhere with the operator in any position relative to the patient. This system of leverage ensures that pressure is transmitted to the patient only. This is an important difference from existing devices where pressure is transmitted to the stretcher thus inflicting up to 10 stones extra pressure on the bearers. This device can be kept wherever respirators such as the ‘Ambu’ or Porton’ are stored, e.g. in mines, ships or ambulances.
