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. 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

This first edition of ISO 80601-2-79, in combination with ISO 80601-2-80 , cancels and replaces
[2]
ISO 10651-6:2004 . This edition of ISO 80601-2-79 constitutes a major technical revision of
ISO 10651-6:2004 and includes an alignment with the third edition of IEC 60601-1, the fourth edition of
IEC 60601-1-2, the third edition of IEC 60601-1-6, the second edition of IEC 60601-1-8 and the second
edition of IEC 60601-1-11.
The most significant changes are the following modifications:
[2]
— splitting the scope of ISO 10651-6:2004 into two parts:
— one for VENTILATORY IMPAIRMENT, also known as RESPIRATORY IMPAIRMENT, (this document) and
— one for VENTILATORY INSUFFIENCY, also known as RESPIRATORY INSUFFICIENCY (ISO 80601-2-80);
— extending the scope to include the VENTILATORY SUPPORT EQUIPMENT and its ACCESSORIES, where the
characteristics of those ACCESSORIES can affect the BASIC SAFETY or ESSENTIAL PERFORMANCE of the
VENTILATORY SUPPORT EQUIPMENT, and thus not the VENTILATORY SUPPORT EQUIPMENT itself;
— identification of ESSENTIAL PERFORMANCE for VENTILATORY SUPPORT EQUIPMENT and its ACCESSORIES;
and the following additions:
— tests for ventilation performance;

Introduction
This document specifies requirements for VENTILATORY SUPPORT EQUIPMENT that is intended for use in the
HOME HEALTHCARE ENVIRONMENT for PATIENTS who are not dependent on ventilation for their life support.
VENTILATORY SUPPORT EQUIPMENT is frequently used in locations where SUPPLY MAINS is not reliable.
VENTILATORY SUPPORT EQUIPMENT is often supervised by non-healthcare personnel (LAY OPERATORS) with
varying levels of training. VENTILATORY SUPPORT EQUIPMENT complying with this document can be used
elsewhere (i.e. in healthcare facilities).
Ventilatory support is often needed for PATIENTS who have stable ventilatory needs. This document
addresses PATIENTS who have significant respiratory dysfunction resulting in an abnormality of a
sufficient degree to be noticeable by the PATIENT. This is best characterized by lung functions not worse
[3]
than :
2
— FEV /FVC < 70 %; or
1
— 50 % ≤ FEV < 80 % predicted
1
where
 FEV is the forced expiratory volume in 1 s, and

 FVC is the forced vital capacity.
Examples of diseases that require ventilation support are
— mild to moderate Chronic Obstructive Pulmonary Disease (COPD);
— neuromuscular/ amyotrophic lateral sclerosis (ALS);
— obese PATIENTS Obese Hypoventilation Syndrome (OHS);
— Cheyne–Stokes respiration (CSR/CSA).
CSR/CSA is an abnormal pattern of breathing characterized by progressively deeper and sometimes
faster breathing, followed by a gradual decrease that results in a temporary stop in breathing called an
apnoea. The pattern repeats, with each cycle usually taking 30 s to 2 min.
Cardiac PATIENTS with CSR/CSA might be breathless without having significant reduction in FEV .

Reducing the work of breathing can help normalize their breathing.
This VENTILATORY SUPPORT EQUIPMENT is intended for PATIENTS who are spontaneously breathing and do
not require ventilation for life support or intermittent periods of ventilation to maintain vital signs.
VENTILATORY SUPPORT EQUIPMENT intended for this group of PATIENTS typically does not require
PHYSIOLOGICAL ALARM CONDITIONS as no ESSENTIAL PERFORMANCE exists. These PATIENTS can gain adequate
relief from fatigue related to the work of breathing by using VENTILATORY SUPPORT EQUIPMENT during the
night and while taking breaks during the day. This can enable a PATIENT with VENTILATORY IMPAIRMENT to
continue to move about and participate in the activities of daily living. Non-TRANSIT-OPERABLE VENTILATORY
SUPPORT EQUIPMENT that provides ventilatory support at the bedside and beside a chair or other resting
place should be adequate in this application.

201.1.3 Collateral standards
Addition:
This document refers to those applicable collateral standards that are listed in Clause 2 of the general
standard and Clause 201.2 of this document.
IEC 60601-1-2:2014, IEC 60601-1-6:2010+AMD1:2013, and IEC 60601-1-11:2015 apply as modified in
[26]
Clauses 202, 206 and 211 respectively. IEC 60601-1-3 does not apply. All other published collateral
standards in the IEC 60601-1 series apply as published.
201.1.4 Particular standards
Replacement:
In the IEC 60601 series, particular standards may 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 the general standard.
For brevity, IEC 60601-1:2005+AMD1:2012 is referred to in this particular 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 that 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 in this document addresses the content of Clause 4 of
the IEC 60601-1-2 collateral standard, 211.10 in this document addresses the content of Clause 10 of the
IEC 60601-1-11 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 the general standard or applicable collateral
standard is replaced completely by the text of this document.
“Addition” means that the text of this document is additional to the requirements of the general standard
or applicable collateral standard.
“Amendment” means that the clause or subclause of the general standard or applicable collateral
standard is amended as indicated by the text of this document.
Subclauses, figures or tables 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
3.147, 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, figures or tables which 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 the general standard, any applicable collateral
standards and this particular standard taken together.
Where there is no corresponding clause or subclause in this particular document, the clause or subclause
of the general standard or applicable collateral standard, although possibly not relevant, applies without
modification; where it is intended that any part of the general standard or applicable collateral standard,
although possibly relevant, is not to be applied, a statement to that effect is given in this particular
document.

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. 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

This first edition of ISO 80601-2-79, in combination with ISO 80601-2-80 , cancels and replaces
[2]
ISO 10651-6:2004 . This edition of ISO 80601-2-79 constitutes a major technical revision of
ISO 10651-6:2004 and includes an alignment with the third edition of IEC 60601-1, the fourth edition of
IEC 60601-1-2, the third edition of IEC 60601-1-6, the second edition of IEC 60601-1-8 and the second
edition of IEC 60601-1-11.
The most significant changes are the following modifications:
[2]
— splitting the scope of ISO 10651-6:2004 into two parts:
— one for VENTILATORY IMPAIRMENT, also known as RESPIRATORY IMPAIRMENT, (this document) and
— one for VENTILATORY INSUFFIENCY, also known as RESPIRATORY INSUFFICIENCY (ISO 80601-2-80);
— extending the scope to include the VENTILATORY SUPPORT EQUIPMENT and its ACCESSORIES, where the
characteristics of those ACCESSORIES can affect the BASIC SAFETY or ESSENTIAL PERFORMANCE of the
VENTILATORY SUPPORT EQUIPMENT, and thus not the VENTILATORY SUPPORT EQUIPMENT itself;
— identification of ESSENTIAL PERFORMANCE for VENTILATORY SUPPORT EQUIPMENT and its ACCESSORIES;
and the following additions:
— tests for ventilation performance;

Introduction
This document specifies requirements for VENTILATORY SUPPORT EQUIPMENT that is intended for use in the
HOME HEALTHCARE ENVIRONMENT for PATIENTS who are not dependent on ventilation for their life support.
VENTILATORY SUPPORT EQUIPMENT is frequently used in locations where SUPPLY MAINS is not reliable.
VENTILATORY SUPPORT EQUIPMENT is often supervised by non-healthcare personnel (LAY OPERATORS) with
varying levels of training. VENTILATORY SUPPORT EQUIPMENT complying with this document can be used
elsewhere (i.e. in healthcare facilities).
Ventilatory support is often needed for PATIENTS who have stable ventilatory needs. This document
addresses PATIENTS who have significant respiratory dysfunction resulting in an abnormality of a
sufficient degree to be noticeable by the PATIENT. This is best characterized by lung functions not worse
[3]
than :
2
— FEV /FVC < 70 %; or
1
— 50 % ≤ FEV < 80 % predicted
1
where
 FEV is the forced expiratory volume in 1 s, and
1
 FVC is the forced vital capacity.
Examples of diseases that require ventilation support are
— mild to moderate Chronic Obstructive Pulmonary Disease (COPD);
— neuromuscular/ amyotrophic lateral sclerosis (ALS);
— obese PATIENTS Obese Hypoventilation Syndrome (OHS);
— Cheyne–Stokes respiration (CSR/CSA).
CSR/CSA is an abnormal pattern of breathing characterized by progressively deeper and sometimes
faster breathing, followed by a gradual decrease that results in a temporary stop in breathing called an
apnoea. The pattern repeats, with each cycle usually taking 30 s to 2 min.
Cardiac PATIENTS with CSR/CSA might be breathless without having significant reduction in FEV .
1
Reducing the work of breathing can help normalize their breathing.
This VENTILATORY SUPPORT EQUIPMENT is intended for PATIENTS who are spontaneously breathing and do
not require ventilation for life support or intermittent periods of ventilation to maintain vital signs.
VENTILATORY SUPPORT EQUIPMENT intended for this group of PATIENTS typically does not require
PHYSIOLOGICAL ALARM CONDITIONS as no ESSENTIAL PERFORMANCE exists. These PATIENTS can gain adequate
relief from fatigue related to the work of breathing by using VENTILATORY SUPPORT EQUIPMENT during the
night and while taking breaks during the day. This can enable a PATIENT with VENTILATORY IMPAIRMENT to
continue to move about and participate in the activities of daily living. Non-TRANSIT-OPERABLE VENTILATORY
SUPPORT EQUIPMENT that provides ventilatory support at the bedside and beside a chair or other resting
place should be adequate in this application.

201.1.3 Collateral standards
Addition:
This document refers to those applicable collateral standards that are listed in Clause 2 of the general
standard and Clause 201.2 of this document.
IEC 60601-1-2:2014, IEC 60601-1-6:2010+AMD1:2013, and IEC 60601-1-11:2015 apply as modified in
[26]
Clauses 202, 206 and 211 respectively. IEC 60601-1-3 does not apply. All other published collateral
standards in the IEC 60601-1 series apply as published.
201.1.4 Particular standards
Replacement:
In the IEC 60601 series, particular standards may 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 the general standard.
For brevity, IEC 60601-1:2005+AMD1:2012 is referred to in this particular 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 that 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 in this document addresses the content of Clause 4 of
the IEC 60601-1-2 collateral standard, 211.10 in this document addresses the content of Clause 10 of the
IEC 60601-1-11 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 the general standard or applicable collateral
standard is replaced completely by the text of this document.
“Addition” means that the text of this document is additional to the requirements of the general standard
or applicable collateral standard.
“Amendment” means that the clause or subclause of the general standard or applicable collateral
standard is amended as indicated by the text of this document.
Subclauses, figures or tables 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
3.147, 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, figures or tables which 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 the general standard, any applicable collateral
standards and this particular standard taken together.
Where there is no corresponding clause or subclause in this particular document, the clause or subclause
of the general standard or applicable collateral standard, although possibly not relevant, applies without
modification; where it is intended that any part of the general standard or applicable collateral standard,
although possibly relevant, is not to be applied, a statement to that effect is given in this particular
document.
