The work of preparing International Standards is normally carried out through ISO t
17、echnical com-mittees. Each member body interested in a subject for which a technical committee has been established has theright to be represented on that committee. International organizations, governmental and non-governmental, in liai-son with ISO, also take part in the work. ISO collaborates clo
18、sely with the International Electrotechnical Commission(IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.Draft International Standards adopted by the technical committees are circulated to
19、 the member bodies for voting.Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.Attention is drawn to the possibility that some of the elements of this part of ISO 5366 may be the subject of patentrights. ISO shall not be held responsible
20、 for identifying any or all such patent rights.International Standard ISO 5366-1 was prepared by Technical Committee ISO/TC 121, Anaesthetic and respiratoryequipment, Subcommittee SC 2, Tracheal tubes and other equipment.This fourth edition cancels and replaces the third edition of ISO 5366-1 and th
21、e second edition of ISO 5366-2(ISO 5366-1:1994 and ISO 5366-2:1993), which have been technically revised.ISO 5366 consists of the following parts, under the general title Anaesthetic and respiratory equipment Tracheos-tomy tubes: Part 1: Tubes and connectors for use in adults Part 3: Paediatric trac
22、heostomy tubesAnnexes A and B form a normative part of this part of ISO 5366. Annex C is for information only.ISO 5366-1:2000(E) ISO 2000 All rights reserved vIntroductionISO 5366-1 is one of a series of International Standards dealing with anaesthetic equipment, and is concerned withthe basic requi
23、rements and method of size designation of tracheostomy tubes made of plastics materials and/or rub-ber. Specialized tubes, for example those without a connector at the machine end intended for spontaneously breath-ing patients, and those with reinforced walls or tubes made of metal are excluded from
24、 the scope of this part ofISO 5366.This part of ISO 5366 specifies requirements for tracheostomy tubes with an inside diameter of or greater.ISO 5366-3 specifies requirements for tracheostomy tubes with an inside diameter from to for paediatricuse.The method of describing tube dimensions and configu
25、ration has been devised in order to assist the clinician in theselection of a suitable tube to conform as far as possible to a particular patients anatomy. Size is designated by in-side diameter, which is important because of its relation to resistance to gas flow. Because the stomal and trachealdia
26、meters are important when selecting tubes, it is considered essential that the outside diameter be stated for eachsize of tube.Cuffed tracheostomy tubes can be characterized by a combination of the tube inside and outside diameters and bythe cuff resting diameter.The relationship of cuff and trachea
27、l diameters dictates the intra-cuff pressures required to provide a seal. Excessivepressure on the tracheal wall can obstruct capillary blood flow.A range of cuff designs is available to meet the particular clinical requirements. This part of ISO 5366 requires thatthe resting diameter of the cuff is
28、 marked on the unit package, as this information allows the clinician to match theproduct to the application.A male conical connector in accordance with ISO 5356-1 should be used for tracheostomy tubes, as for tra-cheal tubes, to ensure compatibility with the breathing system of an anaesthetic machi
29、ne or ventilator.The tracheostomy tube connector should be permanently attached to the tracheostomy tube to prevent inadvertentdisconnection of the connector from the tube.Flammability of tracheostomy tubes, for example if flammable anaesthetics, electrosurgical units, or lasers are usedin oxidant-e
30、nriched atmospheres, is a well-recognized hazard1)that is addressed by appropriate clinical manage-ment, and is outside the scope of this part of ISO 5366.1) See ISO/TR 11991.6,5 mm2,0 6,0 mm15 mmINTERNATIONAL STANDARD ISO 5366-1:2000(E) ISO 2000 All rights reserved 1Anaesthetic and respiratory equi
31、pment Tracheostomy tubes Part 1:Tubes and connectors for use in adults1 ScopeThis part of ISO 5366 specifies requirements for tracheostomy tubes made of plastics materials and/or rubber havinginside diameters of or greater. Such tubes are primarily designed for patients who require anaesthesia, arti
32、-ficial ventilation or other respiratory support, but need not be restricted to these uses.This part of ISO 5366 is not applicable to specialized tubes, and does not address flammability of tracheostomytubes.2 Normative referencesThe following normative documents contain provisions which, through re
