BS EN 794-1:1997+A2:2009, BS 5724-2.202:1997 Lung ventilators
BS EN 794-1:1997+A2:2009 specifies requirements for lung ventilators intended for medical use.
Additional Parts, e.g. concerning emergency and transport ventilators, home care ventilators, and recent developments such as jet and very high frequency ventilation and oscillation are under consideration. Requirements for ventilators intended for anaesthetic applications are given in prEN 740.
