Medical electrical equipment - Part 2-74: Particular requirements for basic safety and essential performance of respiratory humidifying equipment (ISO 80601-2-74:2017)

ISO 80601-2-74:2017 applies to the basic safety and essential performance of a humidifier, also hereafter referred to as me equipment, in combination with its accessories, the combination also hereafter referred to as me system.
ISO 80601-2-74:2017 is also applicable to those accessories intended by their manufacturer to be connected to a humidifier where the characteristics of those accessories can affect the basic safety or essential performance of the humidifier.
EXAMPLE 1 Heated breathing tubes (heated-wire breathing tubes) or me equipment intended to control these heated breathing tubes (heated breathing tube controllers).
NOTE 1 Heated breathing tubes and their controllers are me equipment and are subject to the requirements of IEC 60601‑1.
NOTE 2 ISO 5367 specifies other safety and performance requirements for breathing tubes.
ISO 80601-2-74:2017 includes requirements for the different medical uses of humidification, such as invasive ventilation, non-invasive ventilation, nasal high-flow therapy, and obstructive sleep apnoea therapy, as well as humidification therapy for tracheostomy patients.
NOTE 3 A humidifier can be integrated into other equipment. When this is the case, the requirements of the other equipment also apply to the humidifier.
EXAMPLE 2 Heated humidifier incorporated into a critical care ventilator where ISO 80601‑2-12[12] also applies.
EXAMPLE 3 Heated humidifier incorporated into a homecare ventilator for dependent patients where ISO 80601‑2-72[14] also applies.
EXAMPLE 4 Heated humidifier incorporated into sleep apnoea therapy equipment where ISO 80601‑2-70[13] also applies.
ISO 80601-2-74:2017 also includes requirements for an active hme (heat and moisture exchanger), me equipment which actively adds heat and moisture to increase the humidity level of the gas delivered from the hme to the patient. This document is not applicable to a passive hme, which returns a portion of the expired moisture and heat of the patient to the respiratory tract during inspiration without adding heat or moisture.
NOTE 4 ISO 9360‑1[5] and ISO 9360‑2[6] specify the safety and performance requirements for a passive hme.
If a clause or subclause is specifically intended to be applicable to me equipment only, or to me systems only, the title and content of that clause or subclause will say so. If that is not the case, the clause or subclause applies both to me equipment and to me systems, as relevant.
Hazards inherent in the intended physiological function of me equipment or me systems within the scope of this document are not covered by specific requirements in this document except in IEC 60601‑1:2005+AMD1:2012, 7.2.13 and 8.4.1.
NOTE 5 Additional information can be found in IEC 60601‑1:2005+AMD1:2012, 4.2.
ISO 80601-2-74:2017 does not specify the requirements for cold pass-over or cold bubble-through humidification devices, the requirements for which are given in ISO 20789:?.[8]
This document is not applicable to equipment commonly referred to as "room humidifiers" or humidifiers used in heating, ventilation and air conditioning systems, or humidifiers incorporated into infant incubators.
ISO 80601-2-74:2017 is not applicable to nebulizers used for the delivery of drugs to patients.
NOTE 6 ISO 27427[10] specifies the safety and performance requirements for nebulizers.
ISO 80601-2-74:2017 is a particular standard in the IEC 60601‑1 and the ISO/IEC 80601 series.

Medizinische elektrische Geräte - Teil 2-74: Besondere Festlegungen für die Sicherheit einschließlich der wesentlichen Leistungsmerkmale von Anfeuchtersystemen für Atemgase (ISO 80601-2-74:2017)

IEC 60601 1:2005+AMD1:2012, Abschnitt 1 gilt mit der folgenden Ausnahme:

Appareils électromédicaux - Partie 2-74: Exigences particulières pour la sécurité de base et les performances essentielles des équipements d'humidification respiratoire (ISO 80601-2-74:2017)

ISO 80601-2-74:2017 s'applique à la sécurité de base et aux performances essentielles d'un humidificateur, ci-après également désigné par appareil EM, associé à ses accessoires, dont la combinaison est ci-après désignée par système EM.
ISO 80601-2-74:2017 s'applique également aux accessoires conçus par leur fabricant pour être raccordés à un humidificateur, lorsque les caractéristiques de ces accessoires peuvent affecter la sécurité de base ou les performances essentielles de l'humidificateur.
EXEMPLE 1 Tuyaux respiratoires chauffés (tuyaux respiratoires avec résistance chauffante) ou les appareils EM destinés à commander ces tuyaux respiratoires chauffés (commandes de tuyaux respiratoires chauffés).
NOTE 1 Les tuyaux respiratoires chauffés et leurs commandes sont des appareils EM et sont soumis aux exigences de l'IEC 60601‑1.
NOTE 2 L'ISO 5367 spécifie d'autres exigences de sécurité et de performance pour les tuyaux respiratoires.
ISO 80601-2-74:2017 contient des exigences pour les différentes utilisations médicales de l'humidification, telles que la ventilation invasive, la ventilation non invasive, l'oxygénothérapie nasale à haut débit et le traitement de l'apnée obstructive du sommeil, ainsi que l'humidification pour les patients trachéotomisés.
NOTE 3 Un humidificateur peut être intégré dans un autre appareil. Dans ce cas, les exigences de l'autre appareil s'appliquent aussi à l'humidificateur.
EXEMPLE 2 Humidificateur chauffé intégré dans un ventilateur pulmonaire pour utilisation en soins intensifs où l'ISO 80601‑2‑12[12] s'applique aussi.
EXEMPLE 3 Humidificateur chauffé intégré dans un ventilateur utilisé dans l'environnement des soins à domicile pour les patients dépendants où l'ISO 80601‑2‑72[14] s'applique aussi.
EXEMPLE 4 Humidificateur chauffé intégré dans du matériel de traitement respiratoire de l'apnée du sommeil où l'ISO 80601‑2‑70[13] s'applique aussi.
ISO 80601-2-74:2017 contient également des exigences pour les ECH actifs (échangeurs de chaleur et d'humidité), appareils EM qui ajoutent activement de la chaleur et de l'humidité afin d'augmenter le niveau d'humidité du gaz administré au patient par l'ECH. Le présent document ne s'applique pas aux ECH passifs qui renvoient une partie de l'humidité et de la chaleur de l'air expiré par le patient aux voies respiratoires lors de l'inspiration, sans ajout de chaleur ou d'humidité.
NOTE 4 L'ISO 9360‑1[5] et l'ISO 9360‑2[6] spécifient les exigences de sécurité et de performances pour un ECH passif.
Si un article ou un paragraphe est spécifiquement destiné à être applicable uniquement aux appareils EM ou uniquement aux systèmes EM, le titre et le contenu de cet article ou de ce paragraphe l'indiquent. Dans le cas contraire, l'article ou le paragraphe s'applique à la fois aux appareils EM et aux systèmes EM, selon le cas.
Les dangers inhérents à la fonction physiologique prévue des appareils EM ou des systèmes EM dans le cadre du domaine d'application du présent document ne sont pas couverts par des exigences spécifiques contenues dans le présent document, à l'exception de l'IEC 60601‑1:2005+AMD1:2012, 7.2.13 et 8.4.1.
NOTE 5 L'IEC 60601‑1:2005+AMD1:2012, 4.2 fournit des informations supplémentaires.
ISO 80601-2-74:2017 ne spécifie pas les exigences pour les dispositifs d'humidification à froid par léchage («pass-over») ou à barbotage, dont les exigences sont données dans l'ISO 20789:?[8].
ISO 80601-2-74:2017 ne s'applique pas aux appareils servant à humidifier

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.
The procedures used to develop this document and those intended for its further maintenance
are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria
needed for the different types of ISO documents should be noted. This document was drafted in
accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see
www.iso.org/directives).
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. Details of any patent rights identified during the development of the document will be in
the Introduction and/or on the ISO list of patent declarations received (see
