AB -  JULY The effects of the addition of oxygen to various emergency inflating devices R.C. BIRT, MB, BS, FFARCS Department o f Anzsthesia, St Bartholomew’s Hospital Emergency devices for inflating the lungs usually employ room air. Air is universally available and adequate for most purposes. Such devices are however fitted with an oxygen inlet so that an oxygen rich mixture can be used if the need arises. In pulmonary oedema a high oxygen concentration is of paramount importance. Recently the author was unable to oxygenate a patient with pulmonary oedema adequately with a Drager bag even though 10 litres a minute of oxygen was being added to the inspired mixture. If a Drager bag is examined it will be seen that the oxygen inlet does not enter the bag but is vented into an extremely small reservoir. If oxygen is added most of it spills over into the room air. It was decided that it might be of interest to investigate the effect of adding oxygen, via the inlet tubes provided, to an unmodified Drager bag, a Drager bag with a modified reservoir and to some other commercially available inflating devices. This account deals with the enrichment of the
