Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International
Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
This second edition cancels and replaces the first edition (ISO 5361:1999), which has been technically revised.
The requirements of ISO 5361-4, Tracheal tubes — Part 4: Cole type, have been included in this second
edition because Cole type tracheal tubes are specialized tubes, and as such, are now included in the scope
of this International Standard.
Throughout this Particular Standard, terms defined in Clause 3 or in ISO 4135 appear in bold type.
Throughout this Particular Standard, text for which a rationale is provided in Annex A is indicated by an

Introduction
This International Standard provides the essential performance and safety requirements for the design of
tracheal tubes and tracheal tube connectors. Tracheal tubes are intended to be inserted through the
larynx into the trachea to convey gases and vapours to and from the trachea.
Tracheal tubes with cuffs are intended to seal and protect the trachea from aspiration of secretions and to
provide an unobstructed airway in patients during spontaneous, assisted, or controlled ventilation for short or
prolonged durations.
A variety of cuff designs are available to meet particular clinical requirements. Cuff performance requirements
with associated test methods have been added to this second edition.
Requirements for paediatric tracheal tubes with cuffs have been added because these are commercially
available and in common use.
Tracheal tubes are also intended to conform as closely as possible to human anatomy when in position.
Clinical considerations have also dictated the specified length of tracheal tubes because long tracheal tubes,
sometimes of relatively narrow diameter, may be required and therefore should be readily available. Provision
has also been included for pre-cut tracheal tubes.
Kink resistance requirements with associated test methods have also been added to the second edition to
measure the ability of the shaft of the tracheal tube to resist collapse and increased breathing resistance when
bent or curved.
Radiopacity requirements and test methods have been added to this second edition to characterize the
visibility of tracheal tubes in X-rays used to determine proper placement of the tube. The requirements of this
International Standard were developed using the hazard identification for risk assessment in Annex F.

96 Foreword
97 ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
98 (ISO member bodies). The work of preparing International Standards is normally carried out through ISO
99 technical committees. Each member body interested in a subject for which a technical committee has been
100 established has the right to be represented on that committee. International organizations, governmental and
101 non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
102 International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
103 International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
104 The main task of technical committees is to prepare International Standards. Draft International Standards
105 adopted by the technical committees are circulated to the member bodies for voting. Publication as an
106 International Standard requires approval by at least 75 % of the member bodies casting a vote.
107 ISO 5361 was prepared by Technical Committee ISO/TC 121, Anaesthetic and respiratory equipment,
108 Subcommittee SC 2, Airways and related equipment.
109 This second edition cancels and replaces the first edition of ISO 5361:1999, which has been technically
110 revised.
111 The requirements of this standard were developed using the Hazard Identification for Risk assessment in

ISO/DIS 5361
120 Introduction
121 This standard provides the essential requirements for the design of tracheal tubes and tracheal tube
122 connectors. Tracheal tubes are intended to be inserted through the larynx into the trachea to convey gases
123 and vapours to and from the trachea.
124 Tracheal tubes with cuffs are intended to seal and protect the trachea from aspiration of secretions and to
125 provide an unobstructed airway in patients during spontaneous, assisted, or controlled ventilation for short or
126 prolonged durations.
127 A variety of cuff designs are available to meet particular clinical requirements. Cuff performance requirements
128 and new test methods have been added to the second edition of this International Standard to measure the
129 ability of the cuff to provide a tracheal seal and prevent the leakage and aspiration of fluids.
130 Requirements for cuff placement for paediatric tracheal tubes with cuffs have been added because these
131 are commercially available and in common use.
132 Tracheal tubes are intended to conform as closely as possible to human anatomy when in position.
133 The requirements of ISO 5361-4:2003, Tracheal tubes — Part 4: Cole type, have been included in this
134 revision because Cole type tracheal tubes are specialized tubes, and as such, are now included in the scope
135 of this International Standard.
136 Clinical considerations have also dictated the specified length of tracheal tubes because long tracheal
137 tubes, sometimes of relatively narrow diameter, may be required and therefore should be readily available.
138 Provision has also been included for pre-cut tracheal tubes.
139 Kink resistance requirements and new test methods have also been added to the second edition to measure
140 the ability of the shaft of the tracheal tube to resist collapse and increased breathing resistance when bent or
141 curved.
142 Radiopacity requirements and existing test methods have been added to the second edition to characterize
143 the visibility of tracheal tubes in x-rays used to determine proper placement of the tube. These requirements
[2]
144 were originally published in early ANSI Z-79 standards for tracheal tubes in the 1970’s and 1980’s.

150 Anaesthetic and respiratory equipment — Tracheal tubes and
151 connectors
152 1 *Scope
153 This standard provides the essential requirements for tracheal tubes and tracheal tube connectors.
154 Tracheal tubes with walls reinforced with metal or nylon, tracheal tubes with shoulders, tapering, tracheal
155 tubes with provision for suctioning or monitoring or delivery of drugs or other gases, and the many other types
156 of tracheal tubes devised for specialized applications are included in this specification, as many specialized
157 tracheal tubes are now commonly used, and all share similar essential requirements as defined in this
158 International Standard.
159 Tracheobronchial (endobronchial) tubes, tracheostomy tubes and supralaryngeal airways are excluded from
160 the scope of this International Standard.
161 Tracheal tubes for use with flammable anaesthetic gases or agents and laser or electrosurgical equipment
162 are not covered by this standard.
163 NOTE ISO 11990-1, ISO 11990-2, and ISO 14408 cover this.
164 2 References
165 The following normative documents contain provisions which, through reference in this text, constitute
166 provisions of this International Standard. For dated references, subsequent amendments to, or revisions of,
167 any of these publications do not apply. However, parties to agreements based on this International Standard
