< p class=" p2" > < span lang=" EN-GB" > This document provides the essential requirements for the design of < em style=" mso-bidi-font-style: normal " > supralaryngeal airways< / em> and < em style=" mso-bidi-font-style: normal " > connectors< / em> . 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.< / span>

< p class=" p2" > < span lang=" EN-GB" > This document specifies the dimensions, basic properties and method of size designation of the available types of < em style=" mso-bidi-font-style: normal " > supralaryngeal airways< / em> . 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.< / span>

< p class=" p2" > < span lang=" EN-GB" > 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.< / span>

< p class=" p2" > < span lang=" EN-GB" > This document specifies dimensional disclosure so the operator will know which auxiliary devices, such as tracheal tubes and bronchoscopes will be size-compatible.< / span>

< p class=" p2" > < span lang=" EN-GB" > 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. (See E.1.7).< / span>
