The Dräeger Pulmotor was developed in 1907. It addressed previous concerns about lung injury, by limiting both the inspiratory and expiratory pressures. Although still controversial, the Pulmotor was widely distributed and commercially successful. Oxygen from cylinders provided both the inspiratory gas flow and the driving mechanism. Expiration was an active process and gases were sucked from the lungs by negative pressure created by a Venturi effect. This device came with a facemask and harness, with a caution that the operator should take care to prevent air entering the stomach.Draeger resuscitation kit, inside wooden case with handle.

Mechanical resuscitation devices, such as the Pulmotor and Lungmotor, were popular in the early part of the twentieth century. Their use waned in the 1920s as significant bodies like the British Medical Research Council and American Red Cross refused to endorse them. The most popular of the resuscitators to emerge in the 1930s was the E&J (Ericson and Johnson) resuscitator. The device was soon widely available, vigorously promoted with support from many medical practitioners. They were soon to be found in hospitals, emergency services like the ambulance and fire brigade, and voluntary life-saving organisations. In Australia, Norman James, director of anaesthesia at the Royal Melbourne Hospital, developed an interest in equipment for ambulances and the resuscitation of drowning victims. Little in the way of practical, portable equipment was available to either the ambulances or the voluntary life-saving organisations, such as Surf Life Saving Australia (SLSA); American resuscitators, like the E&J, were expensive and bulky to import. James designed a simple portable resuscitation device for local use after being approached by Jack Conabere, secretary of the Elwood Life Saving Club (ELSC). The resulting Royal Melbourne Hospital resuscitator, or the R.M. resuscitator as it was marketed, was a simpler, manual version of those available overseas. It was gas driven with a plunger, marked “Press”, and a safety valve. The small working unit attached directly to the facemask. Once the patient was positioned facedown and the airway cleared of debris, the mask was placed firmly over the face. The plunger allowed gas to flow and lung inflation; releasing the plunger allowed expiration. This simple resuscitator was marketed by Commonwealth Industrial Gases (CIG) and became very popular in Australia with volunteer and professional rescue organisations. It represents one of the many innovations in resuscitation equipment that resulted from cooperation between volunteer life savers and medical practitioners. Norman James worked closely with Jack Conabere and the Government Pathologist to develop the equipment. ELSC was the first life saving club to use the resuscitator on the beach. While conducting an early training exercise on 23 December 1951, they used it to successfully resuscitate a man who had drowned after capsizing his home made yacht. The R.M. resuscitator was also used in more inventive ways. At Fairfield Hospital in Melbourne, a group of physiotherapists and doctors did some innovative work with polio patients, teaching them glossopharyngeal (or “frog”) breathing, as a means of becoming less dependent on ventilators. In 1981, the Australian Standards Association stated that the RM head failed to meet its revised standards and it was withdrawn from the market.
