Medical electrical equipment - Part 2-79: Particular requirements for basic safety and essential performance of ventilatory support equipment for ventilatory impairment (ISO 80601-2-79:2024)

NOTE 1       There is guidance or rationale for this subclause contained in Clause AA.2.
This document applies to the basic safety and essential performance of ventilatory support equipment, as defined in 201.3.302, for ventilatory impairment, as defined in 201.3.300, hereafter also referred to as ME equipment, in combination with its accessories:
—    intended for use in the home healthcare environment;
NOTE 2       In the home healthcare environment, the supply mains driving the ventilatory support equipment is often not reliable.
NOTE 3       Such ventilatory support equipment can also be used in professional health care facilities.
—    intended for use by a lay operator;
—    intended for use with patients who have ventilatory impairment, the most fragile of these patients, would not likely experience injury with the loss of this artificial ventilation; and
—    not intended for patients who are dependent on artificial ventilation for their immediate life support.
EXAMPLE 1        Patients with mild to moderate chronic obstructive pulmonary disease (COPD).
Ventilatory support equipment is not considered to use a physiologic closed-loop control system unless it uses a physiological patient variable to adjust the artificial ventilation therapy settings.
This document is also applicable to those accessories intended by their manufacturer to be connected to the breathing system of ventilatory support equipment for ventilatory impairment, where the characteristics of those accessories can affect the basic safety or essential performance of the ventilatory support equipment for ventilatory impairment.
EXAMPLE 2        Breathing sets, connectors, water traps, expiratory valve, humidifier, breathing system filter, external electrical power source, distributed alarm system.
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+AMD2:2020, 7.2.13 and 8.4.1.
NOTE 4       Additional information can be found in IEC 60601‑1:2005+AMD1:2012+AMD2:2020, 4.2.
NOTE 5       See ISO/TR 21954 for guidance on the selection of the appropriate ventilator for a given patient. 
This document does not specify the requirements for:
—    ventilators or accessories for ventilator-dependent patients intended for critical care applications, which are given in ISO 80601‑2‑12;
—    ventilators or accessories intended for anaesthetic applications, which are given in ISO 80601‑2‑13;
—    ventilators or accessories intended for the emergency medical services environment, which are given in ISO 80601‑2‑84;
—    ventilators or accessories intended for ventilator-dependent patients in the home healthcare environment, which are given in ISO 80601‑2‑72;
—    ventilatory support equipment or accessories intended for ventilatory insufficiency, which are given in ISO 80601‑2‑80;
—    sleep apnoea therapy ME equipment, which are given in ISO 80601‑2‑70;
—    high-frequency jet ventilators (HFJVs), which are given in ISO 80601‑2‑87;
—    high-frequency oscillatory ventilators (HFOVs);
—    respiratory high flow equipment, which are given in

Appareils électromédicaux - Partie 2-79: Exigences particulières pour la sécurité de base et les performances essentielles des équipements d'assistance ventilatoire en cas de trouble ventilatoire (ISO 80601-2-79:2024)

NOTE 1       L’Article AA.2 contient des recommandations ou une justification pour le présent paragraphe.
Le présent document s’applique à la sécurité de base et aux performances essentielles des équipements d’assistance ventilatoire, tels que définis en 201.3.302, pour un trouble ventilatoire tel que défini en 201.3.300, ci‑après également désignés par appareils EM, en association avec leurs accessoires:
—    destinés à être utilisés dans l’environnement des soins à domicile;
NOTE 2       Dans l’environnement des soins à domicile, il est fréquent que le réseau d’alimentation qui fait fonctionner les équipements d’assistance ventilatoire ne soit pas fiable.
NOTE 3       Ces équipements d’assistance ventilatoire peuvent également être utilisés dans les établissements de santé professionnels.
—    destinés à être utilisés par un opérateur non spécialiste;
—    destinés à être utilisés avec des patients souffrant d’un trouble ventilatoire, les plus fragiles de ces patients ayant peu de risque d’être blessés en cas de perte de cette ventilation artificielle; et
—    non destinés à être utilisés chez les patients dont le maintien immédiat des fonctions vitales dépend d’une ventilation artificielle.
EXEMPLE 1        Patients souffrant d’une bronchopneumopathie chronique obstructive (BPCO) légère à modérée.
Un équipement d’assistance ventilatoire n’est pas considéré comme utilisant un système physiologique de commande en boucle fermée, à moins qu’il n’utilise une variable physiologique du patient pour ajuster les paramètres de traitement par ventilation artificielle.
Le présent document s’applique également aux accessoires conçus par leur fabricant pour être raccordés au système respiratoire des équipements d’assistance ventilatoire en cas de trouble ventilatoire, lorsque les caractéristiques de ces accessoires peuvent affecter la sécurité de base ou les performances essentielles des équipements d’assistance ventilatoire en cas de trouble ventilatoire.
EXEMPLE 2        Ensembles respiratoires, raccords, pièges à eau, valve expiratoire, humidificateur, filtre pour système respiratoire, source d’énergie électrique externe et système d’alarme réparti.
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, suivant 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+AMD2:2020, 7.2.13 et 8.4.1.
NOTE 4       Des informations supplémentaires peuvent être trouvées dans l’IEC 60601‑1:2005+AMD1:2012+AMD2:2020, 4.2.
NOTE 5       Voir l’ISO/TR 21954 pour des recommandations relatives au choix du ventilateur adéquat pour un patient donné. 
Le présent document ne spécifie pas les exigences relatives aux:
—    ventilateurs ou accessoires pour patients ventilo‑dépendants prévus pour les applications en soins intensifs, qui sont données dans l’ISO 80601‑2‑12;
—    ventilateurs ou accessoires prévus pour les applications en anesthésie, qui sont données dans l’ISO 80601‑2‑13;
—    ventilateurs ou accessoires destinés à l’environnement des services médicaux d’urgence, qui

Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are
members of ISO or IEC participate in the development of International Standards through technical
committees established by the respective organization to deal with particular fields of technical activity.
ISO and IEC technical committees collaborate in fields of mutual interest. Other international
organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the
work.
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 document 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 or
www.iec.ch/members_experts/refdocs).
ISO and IEC draw attention to the possibility that the implementation of this document may involve the
use of (a) patent(s). ISO and IEC take no position concerning the evidence, validity or applicability of
any claimed patent rights in respect thereof. As of the date of publication of this document, ISO and IEC
had not received notice of (a) patent(s) which may be required to implement this document. However,
implementers are cautioned that this may not represent the latest information, which may be obtained
