  • Systems for Continuous-Flow Anesthesia 
    Unknown author (WHO, 1994)
    Continuous-flow anaesthetic machines (commonly known as Boyle's machines or simply gas machines) are in widespread use. They rely on a supply of compressed medical gas, either from cylinders attached directly to the machine ...
  • Management of Maintenance 
    Skeet, Muriel; Fear, David (VSO, 1995)
    The breakdown of a piece of equipment is inconvenient to us and can put our patients’ lives at risk. The result is frustration and stress. Sometimes a breakdown is inevitable or a repair is delayed because a spare part ...
