ISO 9360-1:2000(E)
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 3.
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 part of ISO 9360 may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 9360-1 was prepared by Technical Committee ISO/TC 121, Anaesthetic and respiratory
equipment, Subcommittee SC 3, Lung ventilators and related equipment.
This first edition of ISO 9360-1 cancels and replaces, in part, the first edition of ISO 9360 (ISO 9360:1992), which
has been technically revised.
ISO 9360 consists of the following parts, under the general title Anaesthetic and respiratory equipment — Heat and
moisture exchangers (HMEs) for humidifying respired gases in humans:
— Part 1: HMEs for use with minimum tidal volumes of 250 ml
— Part 2: HMEs for use with tracheostomized patients having minimum tidal volumes of 250 ml

ISO 9360-1:2000(E)
Introduction
The gases generally available for medical use lack sufficient moisture to be physiologically acceptable to the
respiratory tract of patients. Heat and moisture exchangers are used to raise the water content and the temperature
of the gas delivered to the respiratory tract. They are primarily intended for use independently or as part of a
breathing system.

This part of ISO 9360 specifies certain requirements for heat and moisture exchangers (HMEs), including those
incorporating breathing system filters, intended for the humidification of respired gases for use primarily with
patients with a tidal volume equal to or greater than 250 ml, and incorporating at least one machine port, and
describes test methods for their evaluation.

5.1 HME patient port connector
The connector at the patient port shall be either a 15 mm female conical connector or a 15 mm female/22 mm male
coaxial connector complying with ISO 5356-1.

c) a thermally insulated chamber (Figure 4), which contains the water bath, the reservoir and a heat source.
6.2.2.3 Air delivery system (Figure 5), consisting of a T-piece with an internal diameter greater than 15 mm,
and an exhaust tube at least 200 mm in length.
6.2.2.4 Weighing equipment, withanaccuracyof � 0,1 g or better in the range of the mass to be measured.
