Anaesthetic and respiratory equipment - Oropharyngeal airways (ISO 5364:2016)

This International Standard specifies requirements for oropharyngeal airways of plastics materials
and/or rubber, including those with a reinforcement insert made of plastics materials and/or metal.
This International Standard is not applicable to metal oropharyngeal airways, nor to requirements
concerning flammability of oropharyngeal airways.
Flammability of oropharyngeal airways, for example, if flammable anaesthetics, electrosurgical units,
or lasers are used, is a well-recognized hazard. It is addressed by appropriate clinical management,
which is outside the scope of this International Standard.
This International Standard is not applicable to supralaryngeal airways without an internal, integral
sealing mechanism.

Anästhesie- und Beatmungsgeräte - Oropharyngealtuben (ISO 5364:2016)

Diese Internationale Norm legt Anforderungen an Oropharyngealtuben aus Kunststoff und/oder Gummi, mit oder ohne Verstärkungseinsatz aus Kunststoff und/oder Metall, fest.
Diese Internationale Norm gilt nicht für Oropharyngealtuben aus Metall und enthält keine Anforderungen an die Entflammbarkeit von Oropharyngealtuben.
Die Entflammbarkeit von Oropharyngealtuben, z. B. bei Anwendung von entflammbaren Anästhesiemitteln, elektrochirurgischen Geräten oder Laser, stellt eine bekannte Gefährdung dar. Sie wird durch entsprechendes klinisches Management berücksichtigt, das jedoch nicht Gegenstand dieser Internationalen Norm ist.
Diese Internationale Norm gilt nicht für supralaryngeale Atemwege ohne einen internen, integrierten Abdichtmechanismus.

Matériel d'anesthésie et de réanimation respiratoire - Canules oropharyngées (ISO 5364:2016)

ISO 5364:2016 spécifie les exigences relatives aux canules oropharyngées en matière plastique et/ou en caoutchouc, notamment celles qui comportent un renfort inséré en matière plastique et/ou en métal.
ISO 5364:2016 ne s'applique pas aux canules oropharyngées en métal, ni ne traite des exigences concernant l'inflammabilité des canules oropharyngées.
L'inflammabilité des canules oropharyngées, par exemple en cas d'utilisation de produits anesthésiques inflammables, d'appareils d'électrochirurgie ou de lasers, représente un danger bien connu. Ce problème est pris en compte par une gestion clinique appropriée, qui ne relève pas du domaine d'application de la présente Norme internationale.
ISO 5364:2016 ne s'applique pas aux canules supralaryngées ne comportant pas de mécanisme d'obturation intégré.

Anestezijska in dihalna oprema - Ustno-žrelne (orofaringealne) dihalne cevke (ISO 5364:2016)

Ta mednarodni standard določa zahteve za orofaringealne dihalne cevke iz plastičnih materialov
in/ali gume, vključno s tistimi z vstavki za ojačanje iz plastičnih materialov in/ali kovine.
Ta mednarodni standard se ne uporablja za kovinske orofaringealne dihalne cevke in za zahteve
glede vnetljivosti orofaringealnih dihalnih cevk.
Vnetljivost orofaringealnih dihalnih cevk, na primer pri uporabi vnetljivih anestetikov, elektrokirurških enot ali laserjev, je dobro poznana nevarnost. Preprečuje se z ustreznim kliničnim upravljanjem, ki ne spada na področje uporabe tega mednarodnega standarda.
Ta mednarodni standard se ne uporablja za supralaringealne dihalne cevke brez notranjega celostnega tesnilnega mehanizma.

Annex ZA
(informative)

Relationship between this European Standard and the Essential
Requirements of EU Directive 93/42/EEC
This European Standard has been prepared under a Commission’s standardization request [M/023
concerning the development of European Standards related to medical devices] / [M/295 concerning
the development of European Standards related to medical devices] / [reference number and title of
any other standardization request as relevant] to provide one voluntary means of conforming to
essential requirements of Council Directive 93/42/EEC of 14 June 1993 concerning medical devices [OJ
L 160].
Once this standard is cited in the Official Journal of the European Union under that Directive,
compliance with the normative clauses of this standard given in Table ZA.1 confers, within the limits of
the scope of this standard, a presumption of conformity with the corresponding essential requirements
of that Directive and associated EFTA regulations.
NOTE 1 Where a reference from a clause of this standard to the risk management process is made, the risk
management process needs to be in compliance with Directive 93/42/EEC as amended by 2007/47/EC. This
means that risks have to be reduced ‘as far as possible’, ‘to a minimum’, ‘to the lowest possible level’, ‘minimized’
or ‘removed’, according to the wording of the corresponding essential requirement.
NOTE 2 The manufacturer’s policy for determining acceptable risk must be in compliance with Essential
Requirements 1, 2, 5, 6, 7, 8, 9, 11 and 12 of the Directive.
NOTE 3 This Annex ZA is based on normative references according to the table of references in the European
foreword, replacing the references in the core text.
NOTE 4 When an Essential Requirement does not appear in Table ZA.1, it means that it is not addressed by this
European Standard.

44 International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
45 The main task of technical committees is to prepare International Standards. Draft International Standards
46 adopted by the technical committees are circulated to the member bodies for voting. Publication as an
47 International Standard requires approval by at least 75 % of the member bodies casting a vote.

60 This International Standard specifies dimensions and other requirements for oropharyngeal airways.
61 Airway size is designated by length, which is important when selecting an oropharyngeal airway to hold
62 forward the base of the tongue to prevent obstruction of the airway by the soft tissues.
63 Airway size is indicated by a legible marking and by a colour code, which are important to allow rapid
64 identification and selection in emergencies.

Anaesthetic and respiratory equipment — Oropharyngeal
airways
1 Scope
This International Standard specifies requirements for oropharyngeal airways of plastics materials and/or
rubber, including those with a reinforcement insert made of plastics materials and/or metal.
This International Standard is not applicable to metal oropharyngeal airways, nor to requirements concerning
flammability of oropharyngeal airways.
Flammability of oropharyngeal airways, for example if flammable anaesthetics, electrosurgical units or lasers
are used, is a well-recognized hazard. It is addressed by appropriate clinical management, which is outside
the scope of this International Standard.
This International Standard is not applicable to supralaryngeal airways without an internal, integral sealing
mechanism.
