It is concerned with the
48、 basic requirements and method of size designation of both open and closed suction catheters made of flexible materials.The method of describing tube dimensions and configuration has been devised in order to assist clinicians in the selection of the most suitable suction catheter for a particular pa
49、tient. Size is designated by outside diameter which is important when selecting a catheter because of its relationship to the ease with which the catheter can be passed through a tracheal or tracheostomy tube.234Revisions in this fourth edition are intended to harmonize this International Standard with recent amendments in the European Medical Device Directive.Major technical revisions in this edition include requirements for closed suction catheters, new requirements to harmonize this International Standard with requirements for critical care ventila
