1、Designation:F 1981 99Standard Specification forSuction Catheters for Use in the Respiratory Tract1This standard is issued under the fixed designation F 1981;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A
2、number in parentheses indicates the year of last reapproval.Asuperscript epsilon(e)indicates an editorial change since the last revision or reapproval.INTRODUCTIONThis specification provides dimensions and requirements for suction catheters for use in therespiratory tract.The basis of this specifica
3、tion is ISO 8836:1997.There are major differences in theaddition of mandatory suction catheter“eyes,”removal of color coding,and inclusion of closed circuitsuction catheters.Size is designated by outside diameter,which is important when selecting catheters,because of itsrelationship to the ease with
4、 which the catheter can be passed through a tracheal or tracheostomy tube(see Specifications F 927,F 1242,F 1627,and F 1666 for details of requirements for tracheal tubesand tracheostomy tubes).Requirements for suction catheters made of rubber have been deletedbecause they are no longer in general u
5、se.1.Scope1.1 This specification provides requirements for suctioncatheters intended for use in suction of the respiratory tract.1.2 Angled-tip suction catheters,for example,Coud cath-eters,and closed circuit suction catheters are not considered tobe specialized,and therefore,are included in this sp
6、ecification.Specialized suction devices are excluded from this specifica-tion.1.3 Flammability of suction catheters,for example if flam-mable anesthetics,electrosurgical units,or lasers are used,is awell-recognized hazard that is addressed by appropriate clini-cal management and is outside the scope
