23、ith the basic requirements and method of size designation of tracheostomy tubes made of plastics materials and/or rubber. EN ISO 5366-1 gives requirements for adult tracheostomy tubes made of plastics materials and/or rubber. This document gives requirements for paediatric tracheostomy tubes with an

24、 inside diameter from 2,0 mm to 6,0 mm. Paediatric tracheostomy tubes are primarily intended for use with infants and children who may require anaesthesia, artificial ventilation, relief of upper airway obstruction or other respiratory therapy. An infant or child differs from an adult, not only in s

25、ize but especially with regard to airway anatomy and respiratory physiology; thus airway equipment for paediatric patients differs from that for adults in size and also in basic design. It should be noted that, although this document gives some requirements for cuffs, cuffs are seldom provided on th

26、e smaller sizes of paediatric tubes. This document gives requirements for those characteristics of tracheostomy tubes that can be standardized and which are important for patient safety. It does not require the connector to be permanently attached to the tube, as this may be impractical with infants

27、 and small children. Other acceptable methods of connecting these components are available, and this document makes provision for them. This document does not limit the range of tube designs needed to match the variety of paediatric anatomy, lesions and space limitations encountered. The method of d

28、escribing tube dimensions and configuration has been devised with the aim of assisting the clinician in the selection of a suitable tube to conform as far as possible to a particular patients anatomy. Size is designated by inside diameter, which is important because of its relation to resistance to

29、gas flow. Because the stomal and tracheal diameters are important when selecting tubes, it is considered essential that the outside diameter be stated for each size of tube. A tracheostomy tube can increase resistance to gas flow. For tubes with a given outside diameter, differences in wall thicknes

30、s have a major influence on the resistance to gas flow, especially in the smaller sizes of paediatric tracheostomy tubes. Flammability of tracheostomy tubes, for example if flammable anaesthetics, electrosurgical units or lasers are used in oxidant-enriched atmospheres, is a well-recognized hazard1a

31、ddressed by appropriate clinical management, which is outside the scope of this document. 1See ISO/TR 11991. BS EN 1282-2:2005+A1:2009EN 1282-2:2005+A1:2009 (E) 5 1 Scope This European Standard specifies requirements for paediatric tracheostomy tubes made of plastics materials and/or rubber having i

32、nside diameters from 2,0 mm to 6,0 mm. Requirements for paediatric tracheostomy tube connectors and adaptors are also given.
