CSA ISO 11712:24

CSA Preface This is the second edition of CSA ISO 11712, Anaesthetic and respiratory equipment — Supralaryngeal airways and connectors, which is an adoption without modification of the identically titled ISO (International Organization for Standardization) Standard, ISO 11712:2023 (second edition, 2023-11). It supersedes the previous edition, published in 2014 as CSA ISO 11712:14 (adopted ISO 11712:2009). For brevity, this Standard will be referred to as "CSA ISO 11712" throughout. CSA Group acknowledges that the adoption of this Standard was made possible, in part, by the financial support of the governments of Alberta, British Columbia, Manitoba, New Brunswick, Newfoundland and Labrador, Northwest Territories, Nova Scotia, Nunavut, Ontario, Prince Edward Island, Quebec, Saskatchewan, and Yukon, as administered by the Canada’s Drug Agency (CDA-AMC). This Standard was reviewed for Canadian adoption by the CSA Technical Committee on Perioperative Safety, under the jurisdiction of the Strategic Steering Committee on Health and Well-being, and has been formally approved by the Technical Committee. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. Scope NOTE There is guidance or rationale for this Clause in Annex A.2. 1.1 This document provides the essential requirements for the design of supralaryngeal airways and connectors. These devices are intended to provide a distinct respiratory pathway to the top of the larynx to provide an unobstructed airway in patients during spontaneous, assisted or controlled ventilation. 1.2 This document specifies the dimensions, basic properties and method of size designation of the available types of supralaryngeal airways. Airways devised for specialized applications are not specifically covered, although most may be classified by the sizing and dimensions (or other characteristics) required by this document. 1.3 The following devices are outside the scope of this document: nasal and oropharyngeal airways, anesthetic masks, oro- and naso-tracheal tubes, cricothyrotomy devices, dental appliances, tracheal stents, tracheal tubes, ventilating laryngoscopes, CPAP devices, esophageal obturators, bougies and devices that require surgical placement. 1.4 This document specifies dimensional disclosure so the operator will know which auxiliary devices, such as tracheal tubes and bronchoscopes will be size-compatible. 1.5 Flammability of airways, for example if used with certain flammable anesthetic gases, electrosurgical units or lasers, is a well-recognized hazard that is outside the scope of this document.
