CSA Preface
This is the second edition of CAN/CSA-Z7376, Anaesthetic and respiratory equipment - Laryngoscopes for tracheal intubation, which is an adoption, with Canadian deviations, of the identically titled ISO (International Organization for Standardization) Standard 7376 (second edition, 2009-08-15). It supersedes the previous edition published in 2007 as CAN/CSA-Z7376 (adopted ISO 376:2003).
This Standard was reviewed for Canadian adoption by the CSA Technical Committee on Perioperative Safety, under the jurisdiction of the CSA Strategic Steering Committee on Health Care Technology, and has been formally approved by the Technical Committee. This Standard has been approved as a National Standard of Canada by the Standards Council of Canada.
Scope
This International Standard gives general requirements for laryngoscopes used for intubation, and specifies critical dimensions for the handle and lamp of hook-on type laryngoscopes. It also addresses the interchangeability of blades and handles.
It is applicable only to instruments with an internal battery-operated power source for illuminating the larynx, since electrical safety requirements can be more stringent for instruments connected to mains or external power packs.
It is not applicable to surgical instruments known by the same generic name, nor is it applicable to
- flexible laryngoscopes or laryngoscopes designed for surgery
- laryngoscopes powered from mains electricity supply
- laryngoscopes connected by light-transmitting cables to external light sources, or
- video laryngoscopes designed to work with an external video system.
NOTE Instruments connected by light guides to an external light source could be subject to other International Standards.
