Testing Gas Supply and Suction


  • check each bed space
  • labeling
  • colour coding
  • sleeve index system
  • in a level 3 unit: 3 O2, 2 air and 3 suction outlets


  • correct gas for outlet
  • purity of gas
  • check oxygen concentrations at all outlets (this will distinguish between O2, air and other gases)
  • sniff test for objectionable odours at medical air outlets only
  • if a non-respirable gas present -> testing should be performed by an anaesthetist

Flow rate and Pressure

  • using a device that fits the outlet (pressure manometer, variable flow restrictor and a flow meter)
  • air and O2: static pressure 415kPa, then set flow rate to 40L/min -> change in pressure should be less than 10kPa
  • suction: static pressure -60kPa -> change flow rate to 40L/min -> change in pressure should be less than 15kPa.

Testing of Alarms

  • turn off the isolating valve for each supplied gas in turn -> ensure that visible and audible alarms activate.
