CSA Preface

This is the second edition of CAN/CSA-ISO 5364, Anaesthetic and respiratory equipment - Oropharyngeal airways, which is an adoption without modification of the identically titled ISO (International Organization for Standardization) Standard 5364 (fifth edition, 2016-09-01). It supersedes the previous edition published in 2014 as CAN/CSA-ISO 5364 (adopted ISO 5364:2008). For brevity, this Standard will be referred to as "CAN/CSA-ISO 5364" throughout.

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.
