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.
Amendment 1 to ISO 5145:2004 was prepared by Technical Committee ISO/TC 58, Gas cylinders,
Subcommittee SC 2, Cylinder fittings.

Cylinder valve outlets for gases and gas mixtures — Selection
and dimensioning
AMENDMENT 1: Cylinder valve outlets for gases for medical use
Add the following annex after Annex C:
Annex D
(informative)
Cylinder valve outlets for gases for medical use
D.1 Scope
This annex gives examples of how to allocate cylinder valve outlets in the case of gases for medical use to
ensure patient safety. Such gases are treated differently depending on whether they are gases for inhalation
or for other purposes. Allocation is based on the pharmacological and therapeutic properties of the gases and
not physical aspects such as pressure.
D.2 Definitions
The following definitions apply.
D.2.1 Gas for medical use
Any gas or mixture of gases intended to be administered to patients for therapeutic, diagnostic or prophylactic
purposes, with or without pharmacological action, or to be used for surgical tools. It covers both medicinal and
medical gases.
D.2.2 Medicinal gas
Any gas or mixture of gases intended to be administered to patients for therapeutic, diagnostic or prophylactic
purposes using pharmacological action and classified as a medicinal product, e.g. according to Article 1.2 of
Directive 2001/83/EC of the European Parliament and of the Council of 6 November 2001 on the community
code relating to medicinal products for human use.
D.2.3 Gas for inhalation
Medicinal gas intended for introduction into the body through respiration. The gas is administered alone
directly or after mixing at the point of use with oxygen or air.

D.2.4 Medicinal gas mixture containing oxygen
Gas mixture in which the oxygen content is taken into account in order to limit the duration of the inhalation
under standard atmospheric conditions, for example binary mixtures (from nitrogen, helium, nitrous oxide,
carbon dioxide) or ternary mixtures or more used e.g. for lung function testing (LFT). Medicinal gas mixtures
containing oxygen can be classified as follows.
1)
⎯ Hypoxic mixtures (mixtures with lower than normal O content): gas with O < 20 % for short-term
2 2
inhalation.
⎯ Hyperoxic mixtures (mixtures with greater than normal O content): gas with O > 23,5 % for continuous
2 2
inhalation.
1)
⎯ Normoxic mixtures (mixtures with normal O content): 20 % u O u 23,5 % for continuous inhalation.
2 2
D.2.5 Analytical gas
Gas which is used for analysis calibration or for the purpose of supplying energy (flame, oven, etc.) and other
similar purposes (for example, gas chromatography, atomic absorption spectrophotometer) in biological or
pharmaceutical research laboratories.
D.2.6 Breathable gas
Gas which supports life to be used in breathing or diving apparatus in a non-standard atmospheric medium
such as water, at high
