BS EN ISO 5364:2016 pdf free download.Anaesthetic and respiratory equipment Oropharyngeal airways ( IS0 5364 : 2016).
I Scope
BS EN ISO 5364 specifies requirements for oropharyngeal airways of plastics materials and/or rubber. including those with a reinforcement insert made of plastics materials and/or metal.
BS EN ISO 5364 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 BS EN ISO 5364.
BS EN ISO 5364 Is not applicable to supralaryngeal airways without an Internal, integral sealing mechanism.
