Introduction
Le présent document spécifie les exigences relatives aux ventilateurs pulmonaires destinés à être utilisés
dans l’environnement des soins à domicile pour les patients dépendants d’une ventilation pour le
maintien de leurs fonctions vitales. Ces ventilateurs sont fréquemment utilisés dans des endroits où le
réseau d’alimentation qui fait fonctionner le ventilateur n’est pas fiable. Ces ventilateurs sont souvent
surveillés par du personnel non médical (opérateurs non spécialistes) ayant des niveaux de formation
variables. Les ventilateurs pulmonaires conformes à la présente norme peuvent être utilisés ailleurs
(c’est-à-dire dans des établissements de soins).
En ce qui concerne la structure du présent document :
— «article » désigne l’une des 5 sections numérotées dans la table des matières, avec toutes ses
subdivisions (par exemple l’Article 201 inclut les paragraphes 201.7, 201.8, etc.) ; et
— «paragraphe » désigne l’une des subdivisions numérotées d’un article (par exemple, 201.7, 201.8 et
201.9 sont tous des paragraphes de l’Article 201).
Dans le présent document, les références à des articles sont précédées du mot «Article » suivi du
numéro de l’article concerné. Les références aux paragraphes du présent document sont présentées
sous forme de numéro uniquement.
Dans le présent document, la conjonction «ou » est utilisée comme « ou inclusif » ; une affirmation est
donc vraie si une combinaison quelconque des conditions est vraie.
Aux fins du présent document :
— « doit » indique une exigence ;
— « il convient de/que » indique une recommandation ;
— « peut/il est admis/permis » indique une autorisation ;
— le verbe « pouvoir » (« can » en anglais) indique une possibilité ou une capacité ; et

l’IEC 60601-1:2005+AMD1:2012+AMD2:2020 ou de la norme collatérale applicable est amendé
comme indiqué par le texte du présent document.
Les paragraphes ou figures qui s’ajoutent à ceux de la norme générale sont numérotés à partir de
201.101. Toutefois, compte tenu du fait que les définitions données dans la norme générale sont
© ISO 2023 – Tous droits réservés 3

---------------------- Page: 10 ----------------------
ISO 80601-2-72:2023(F)
numérotées de 3.1 à 3.154, les définitions supplémentaires apparaissant dans le présent document sont
numérotées à partir de 201.3.201. Les annexes supplémentaires sont indiquées par les lettres AA, BB,
etc., et les éléments supplémentaires par aa), bb), etc.
Les paragraphes ou figures qui s’ajoutent à ceux d’une norme collatérale sont numérotés à partir
de 20x, où « x » est le numéro de la norme collatérale (202 pour l’IEC 60601-1-2, 203 pour
l’IEC 60601-1-3, etc., par exemple).
L’expression « le présent document » permet de faire référence en même temps à
l’IEC 60601-1:2005+AMD1:2012+AMD2:2020, aux normes collatérales applicables et au présent

Introduction
This document specifies requirements for lung ventilators that are intended for use in the home
healthcare environment for patients who are dependent for ventilation for their life support. These
ventilators are frequently used in locations where the supply mains driving the ventilator is not reliable.
These ventilators are often supervised by non-healthcare personnel (lay operators) with varying levels
of training. Lung ventilators conforming with this standard can be used elsewhere (i.e. in healthcare
facilities).
In referring to the structure of this document,
— “clause” means one of the 5 numbered divisions within the table of contents, inclusive of all
subdivisions (e.g. Clause 201 includes 201.7, 201.8, etc.), and
— “subclause” means a numbered subdivision of a clause (e.g. 201.7, 201.8 and 201.9 are all
subclauses of Clause 201).
References to clauses within this document are preceded by the term “Clause” followed by the clause
number. References to subclauses within this document are by number only.
In this document, the conjunctive “or” is used as an “inclusive or” so a statement is true if any
combination of the conditions is true.
For the purposes of this document, the auxiliary verb:
— “shall” indicates a requirement;
— “should” indicates a recommendation;
— “may” indicates a permission;
— "can" is used to describe a possibility or capability; and
— "must" is used to express an external constraint.

FINAL DRAFT INTERNATIONAL STANDARD ISO/FDIS 80601-2-72:2023(E)

Medical electrical equipment —
Part 2-72:
Particular requirements for basic safety and essential
performance of home healthcare environment ventilators for
ventilator-dependent patients
201.1 Scope, object, and related standards
IEC 60601-1:2005+AMD1:2012+AMD2:2020, Clause 1 applies, except as follows:
201.1.1 Scope
Replacement:
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 a ventilator in combination with
its accessories, hereafter referred to as ME equipment:
— intended for use in the home healthcare environment;
NOTE 2 In the home healthcare environment, the supply mains driving the ventilator is often not reliable.
NOTE 3 Such ventilators can also be used in non-critical care applications of professional healthcare facilities.
— intended for use by a lay operator; and
— intended for those patients who need differing levels of support from artificial ventilation including
for ventilator-dependent patients.
A ventilator is not considered to use a physiologic closed-loop control system unless it uses a
physiological patient variable to adjust the ventilation therapy settings.
This document is also applicable to those accessories intended by their manufacturer to be connected to
a ventilator breathing system or to a ventilator where the characteristics of those accessories can affect
the basic safety or essential performance of the ventilator.
EXAMPLE Breathing tubes, connectors, water traps, expiratory valve, humidifier, breathing system filter,
external electrical power source, and distributed alarm system.
NOTE 4 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 for the
requirements specified in IEC 60601-1:2005+AMD1:2012+AMD2:2020, 7.2.13 and 8.4.1.
NOTE 5 Additional information can be found in IEC 60601-1:2005+AMD1:2012+AMD2:2020, 4.2.

---------------------- Page: 9 ----------------------
ISO/FDIS 80601-2-72:2023(E)
IEC 60601-1-2:2014+AMD1:2020, IEC 60601-1-6:2010+AMD1:2013+AMD2:2020,
IEC 60601-1-8:2016+AMD1:2012+AMD2:2020 and IEC 60601-1-11:2015+AMD1:2020 apply as
modified in Clauses 202, 206, 208 and 211 respectively. IEC 60601-1-3, IEC 60601-1-9 and
IEC 60601-1-12 do not apply.
201.1.4 Particular standards
Replacement:
In the IEC 60601 series, particular standards can modify, replace, or delete requirements contained in
the general standard, including the collateral standards, as appropriate for the particular ME equipment
under consideration, and may add other basic safety or essential performance requirements.
A requirement of a particular standard takes priority over IEC 60601-1:2005+AMD1:2012+AMD2:2020
or the collateral standards.
For brevity, IEC 60601-1:2005+AMD1:2012+AMD2:2020 is referred to in this document as the general
standard. Collateral standards are referred to by their document number.
The numbering of clauses and subclauses of this document corresponds to those of the general
standard with the prefix “201” (e.g. 201.1 in this document addresses the content of Clause 1 of the
general standard) or applicable collateral standard with the prefix “2xx” where xx is the final digits of
the collateral standard document number (e.g. 202.4 addresses the content of IEC 60601-1-2, Clause 4
collateral standard, 208.4 addresses the content of IEC 60601-1-8, Clause 4 collateral standard, etc.).
The changes to the text of the general standard are specified by the use of the following words:
— “Replacement” means that the clause or subclause of IEC 60601-1:2005+AMD1:2012+AMD2:2020
or the applicable collateral standard is replaced completely by the text of this document.
— “Addition” means that the text of this particular standard is additional to the requirements of
IEC 60601-1:2005+AMD1:2012+AMD2:2020 or the applicable collateral standard.
— “Amendment” means that the clause or subclause of IEC 60601-1:2005+AMD1:2012+AMD2:2020
or the applicable collateral standard is amended as indicated by the text of this document.
Subclauses or figures that are additional to those of the general standard are numbered starting from
201.101. However, due to the fact that definitions in the general standard are numbered 3.1 through
3.154, additional definitions in this document are numbered beginning from 201.3.201. Additional
annexes are lettered AA, BB, etc., and additional items aa), bb), etc.
Subclauses or figures that are additional to those of a collateral standard are numbered starting from
20x, where “x” is the number of the collateral standard, e.g. 202 for IEC 60601-1-2, 203 for
IEC 60601-1-3, etc.
The term “this document” is used to make reference to IEC 60601-1:2005+AMD1:2012+AMD2:2020,
any applicable collateral standards, and this document taken together.
Where there is no corresponding clause or subclause in this document, the clause or subclause of
IEC 60601-1:2005+AMD1:2012+AMD2:2020 or the applicable collateral standard, although possibly
not relevant, applies without modification; where it is intended that any part of
IEC 60601-1:2005+AMD1:2012+AMD2:2020 or the applicable collateral standard, although possibly
relevant, is not to be applied, a statement to that effect is given in this document.
201.2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.

Introduction
This document specifies requirements for lung ventilators that are intended for use in the home
healthcare environment for patients who are dependent for ventilation for their life support. These
ventilators are frequently used in locations where the supply mains driving the ventilator is not reliable.
These ventilators are often supervised by non-healthcare personnel (lay operators) with varying levels
of training. Lung ventilators conforming with this standard can be used elsewhere (i.e. in healthcare
facilities).
In referring to the structure of this document,
— “clause” means one of the 5 numbered divisions within the table of contents, inclusive of all
subdivisions (e.g. Clause 201 includes 201.7, 201.8, etc.), and
— “subclause” means a numbered subdivision of a clause (e.g. 201.7, 201.8 and 201.9 are all
subclauses of Clause 201).
References to clauses within this document are preceded by the term “Clause” followed by the clause
number. References to subclauses within this document are by number only.
In this document, the conjunctive “or” is used as an “inclusive or” so a statement is true if any
combination of the conditions is true.
For the purposes of this document, the auxiliary verb:
— “shall” indicates a requirement;
— “should” indicates a recommendation;
— “may” indicates a permission;
— "can" is used to describe a possibility or capability; and
— "must" is used to express an external constraint.

FINAL DRAFT INTERNATIONAL STANDARD ISO/FDIS 80601-2-72:2023(E)

Medical electrical equipment —
Part 2-72:
Particular requirements for basic safety and essential
performance of home healthcare environment ventilators for
ventilator-dependent patients
201.1 Scope, object, and related standards
IEC 60601-1:2005+AMD1:2012+AMD2:2020, Clause 1 applies, except as follows:
201.1.1 Scope
Replacement:
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 a ventilator in combination with
its accessories, hereafter referred to as ME equipment:
— intended for use in the home healthcare environment;
NOTE 2 In the home healthcare environment, the supply mains driving the ventilator is often not reliable.
NOTE 3 Such ventilators can also be used in non-critical care applications of professional healthcare facilities.
— intended for use by a lay operator; and
— intended for those patients who need differing levels of support from artificial ventilation including
for ventilator-dependent patients.
A ventilator is not considered to use a physiologic closed-loop control system unless it uses a
physiological patient variable to adjust the ventilation therapy settings.
This document is also applicable to those accessories intended by their manufacturer to be connected to
a ventilator breathing system or to a ventilator where the characteristics of those accessories can affect
the basic safety or essential performance of the ventilator.
EXAMPLE Breathing tubes, connectors, water traps, expiratory valve, humidifier, breathing system filter,
external electrical power source, and distributed alarm system.
NOTE 4 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 for the
requirements specified in IEC 60601-1:2005+AMD1:2012+AMD2:2020, 7.2.13 and 8.4.1.
NOTE 5 Additional information can be found in IEC 60601-1:2005+AMD1:2012+AMD2:2020, 4.2.

ISO/FDIS 80601-2-72:2023(E)
IEC 60601-1-2:2014+AMD1:2020, IEC 60601-1-6:2010+AMD1:2013+AMD2:2020,
IEC 60601-1-8:2016+AMD1:2012+AMD2:2020 and IEC 60601-1-11:2015+AMD1:2020 apply as
modified in Clauses 202, 206, 208 and 211 respectively. IEC 60601-1-3, IEC 60601-1-9 and
IEC 60601-1-12 do not apply.
201.1.4 Particular standards
Replacement:
In the IEC 60601 series, particular standards can modify, replace, or delete requirements contained in
the general standard, including the collateral standards, as appropriate for the particular ME equipment
under consideration, and may add other basic safety or essential performance requirements.
A requirement of a particular standard takes priority over IEC 60601-1:2005+AMD1:2012+AMD2:2020
or the collateral standards.
For brevity, IEC 60601-1:2005+AMD1:2012+AMD2:2020 is referred to in this document as the general
standard. Collateral standards are referred to by their document number.
The numbering of clauses and subclauses of this document corresponds to those of the general
standard with the prefix “201” (e.g. 201.1 in this document addresses the content of Clause 1 of the
general standard) or applicable collateral standard with the prefix “2xx” where xx is the final digits of
the collateral standard document number (e.g. 202.4 addresses the content of IEC 60601-1-2, Clause 4
collateral standard, 208.4 addresses the content of IEC 60601-1-8, Clause 4 collateral standard, etc.).
The changes to the text of the general standard are specified by the use of the following words:
— “Replacement” means that the clause or subclause of IEC 60601-1:2005+AMD1:2012+AMD2:2020
or the applicable collateral standard is replaced completely by the text of this document.
— “Addition” means that the text of this particular standard is additional to the requirements of
IEC 60601-1:2005+AMD1:2012+AMD2:2020 or the applicable collateral standard.
— “Amendment” means that the clause or subclause of IEC 60601-1:2005+AMD1:2012+AMD2:2020
or the applicable collateral standard is amended as indicated by the text of this document.
Subclauses or figures that are additional to those of the general standard are numbered starting from
201.101. However, due to the fact that definitions in the general standard are numbered 3.1 through
3.154, additional definitions in this document are numbered beginning from 201.3.201. Additional
annexes are lettered AA, BB, etc., and additional items aa), bb), etc.
Subclauses or figures that are additional to those of a collateral standard are numbered starting from
20x, where “x” is the number of the collateral standard, e.g. 202 for IEC 60601-1-2, 203 for
IEC 60601-1-3, etc.
The term “this document” is used to make reference to IEC 60601-1:2005+AMD1:2012+AMD2:2020,
any applicable collateral standards, and this document taken together.
Where there is no corresponding clause or subclause in this document, the clause or subclause of
IEC 60601-1:2005+AMD1:2012+AMD2:2020 or the applicable collateral standard, although possibly
not relevant, applies without modification; where it is intended that any part of
IEC 60601-1:2005+AMD1:2012+AMD2:2020 or the applicable collateral standard, although possibly
relevant, is not to be applied, a statement to that effect is given in this document.
