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 2.
The main task of technical committees is to prepare International Standards. 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 document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO/IEC 80601-2-70 was prepared by a joint working group of Technical Committee ISO/TC 121, Anaesthetic
and respiratory equipment, Subcommittee SC 3, Lung ventilators and related equipment and Technical
Committee IEC/TC 62, Electrical equipment in medical practice, Subcommittee SC D, Electrical equipment.
This first edition of ISO 80601-2-70 cancels and replaces the second edition of ISO 17510-1:2007. This
edition of ISO 80601-2-70 constitutes a technical revision of ISO 17510-1:2007 and includes an alignment
with third edition of IEC 60601-1 and IEC 60601-1-11.
The most significant changes are the following modifications:
 identification of ESSENTIAL PERFORMANCE for SLEEP APNOEA BREATHING THERAPY EQUIPMENT and its
ACCESSORIES;
and the following additions:
 tests for therapy performance; and
 new symbols.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
In this standard, the following print types are used:
 Requirements and definitions: roman type.
 Test specifications: italic type.
 Informative material appearing outside of tables, such as notes, examples and references: smaller type. Normative
text of tables is also in a smaller type.
 TERMS DEFINED IN CLAUSE 3 OF THE GENERAL STANDARD, IN THIS PARTICULAR STANDARD OR AS NOTED: SMALL
CAPITALS TYPE.

 "clause” means one of the seventeen numbered divisions within the table of contents, inclusive of all
subdivisions (e.g. Clause 7 includes subclauses 7.1, 7.2, etc.);
 “subclause” means a numbered subdivision of a clause (e.g. 201.7.1, 201.7.2 and 201.7.2.1 are all
subclauses of Clause 201.7).
References to clauses within this standard are preceded by the term “Clause” followed by the clause number.
References to subclauses within this particular standard are by number only.
In this standard, the conjunctive “or” is used as an “inclusive or” so a statement is true if any combination of
the conditions is true.
The verbal forms used in this standard conform to usage described in Annex H of the ISO/IEC Directives, Part
2. For the purposes of this standard, the auxiliary verb:
 “shall” means that compliance with a requirement or a test is mandatory for compliance with this
standard;
 “should” means that compliance with a requirement or a test is recommended but is not mandatory for
compliance with this standard;
 “may” is used to describe a permissible way to achieve compliance with a requirement or test.
An asterisk (*) as the first character of a title or at the beginning of a paragraph or table title indicates that
there is guidance or rationale related to that item in Annex AA.
The attention of Member Bodies and National Committees is drawn to the fact that equipment manufacturers
and testing organizations may need a transitional period following publication of a new, amended or revised
ISO or IEC publication in which to make products in accordance with the new requirements and to equip
themselves for conducting new or revised tests. It is the recommendation of the committee that the content of
this publication not be adopted for mandatory implementation nationally earlier than 3 years from the date of
publication for equipment newly designed and not earlier than 5 years from the date of publication for
equipment already in production.

Introduction
Sleep apnoea is a chronic medical condition where the PATIENT repeatedly stops breathing during sleep.
These episodes typically last 10 s or more and cause the oxygen levels in the blood to drop. It can be caused
by obstruction of the upper airway (obstructive sleep apnoea or OSA) or by a failure of the brain to initiate a
breath (central sleep apnoea).
NOTE SLEEP APNOEA BREATHING THERAPY EQUIPMENT is intended for the treatment of obstructive sleep apnoea and not
central sleep apnoea.
Sleep apnoea, if untreated, can cause and worsen other medical conditions, including hypertension, heart
1
failure and diabetes .
Hypopnoea refers to a transient reduction of airflow, often while the PATIENT is asleep, that lasts for at least
10 s, shallow breathing, or an abnormally low respiratory rate. Hypopnoea is less severe than apnoea. It also
results in decreased air movement into the lungs and can cause oxygen levels in the blood to drop. It is
2
commonly due to partial obstruction of the upper airway. [16]
Awareness of the RISKS associated with sleep apnoea has grown significantly. As a result, the use of SLEEP
APNOEA BREATHING THERAPY EQUIPMENT to treat both sleep apnoea and hypopnoea has become common.
This document covers BASIC SAFETY and ESSENTIAL PERFORMANCE requirements needed to protect PATIENTS in
the use of this ME EQUIPMENT.
ISO 80601-2-70 covers SLEEP APNOEA BREATHING THERAPY EQUIPMENT for PATIENT use. ISO 17510 applies to
MASKS and ACCESSORIES used to connect SLEEP APNOEA BREATHING THERAPY EQUIPMENT to the PATIENT. Figure
AA.1 shows this diagrammatically.

are dependent on mechanical ventilation such as PATIENTS with central sleep apnoea.
This particular standard is also applicable to those ACCESSORIES intended by their MANUFACTURER to be
connected to SLEEP APNOEA BREATHING THERAPY EQUIPMENT, where the characteristics of those ACCESSORIES
can affect the BASIC SAFETY or ESSENTIAL PERFORMANCE of the SLEEP APNOEA BREATHING THERAPY EQUIPMENT.
MASKS and application ACCESSORIES intended for use during sleep apnoea breathing therapy are additionally
3)
addressed by ISO 17510. Refer to Figure AA.1 for items covered further under this standard.
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 standard are not covered by specific requirements in this standard except in 7.2.13 and 8.4.1 of the
general standard.

201.1.3 Collateral standards
IEC 60601-1:2005+A1:2012, 1.3 applies with the following addition:
This particular standard refers to those applicable collateral standards that are listed in Clause 2 of the
general standard and 201.2 of this particular standard.
IEC 60601-1-3:2008 does not apply.
201.1.4 Particular standards

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 or the collateral standards.
For brevity, IEC 60601-1:2005+A 1:2012 is referred to in this particular standard as the general standard.
Collateral standards are referred to by their document number.
