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
[25]
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. It also results in arousal or can cause oxygen saturation to drop. Hypopnoea is less
[23]
severe than apnoea. It is commonly due to partial obstruction of the upper airway .
Awareness of the risks associated with obstructive sleep apnoea has grown significantly. As a result, the use
of sleep apnoea breathing therapy equipment to treat obstructive sleep apnoea has become common.
This document covers basic safety and essential performance requirements needed to protect patients in the
use of this ME equipment.
This document 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.
In this document, the following print types are used:
— Requirements and definitions: roman type
— Terms defined in clause 3 of the general standard, in this document or as noted: italic type;
— Informative material appearing outside of tables, such as notes, examples and references: in smaller type.
Normative text of tables is also in a smaller type;
In referring to the structure of this document, the term.
— “clause” means one of the four numbered divisions within the table of contents, inclusive of all
subdivisions (e.g. Clause 201 includes subclauses 201.1, 201.2, etc.);
— “subclause” means a numbered subdivision of a clause (e.g. 201.101, 201.102 and 201.102.1 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.

1 Scope
NOTE 1 There is guidance or rationale for this subclause contained in Clause AA.2.1.
IEC 60601-1:2005+AMD1:2012+AMD2:2020, 1.1 is replaced by:
This document is applicable to the basic safety and essential performance of sleep apnoea breathing therapy
equipment, hereafter referred to as ME equipment, intended to alleviate the symptoms of patients who suffer
from obstructive sleep apnoea by delivering a therapeutic breathing pressure to the respiratory tract of the
patient. Sleep apnoea breathing therapy equipment is intended for use in the home healthcare environment by
lay operators as well as in professional healthcare institutions.
Sleep apnoea breathing therapy equipment is not considered to utilize a physiologic closed-loop-control system
unless it uses a physiological patient variable to adjust the therapy settings.
This document excludes sleep apnoea breathing therapy equipment intended for use with neonates.
This document is applicable to ME equipment or an ME system intended for those patients who are not
dependent on artificial ventilation. This document is not applicable to ME equipment or an ME system
intended for those patients who are dependent on artificial ventilation such as patients with central sleep
apnoea.
This document 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
addressed by ISO 17510. Refer to Figure AA.1 for items covered further under this document.
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.
ISO 80601-2-70:2025(en)

IEC 60601-1:2005+AMD1:2012+AMD2:2020, 1.3 applies with the following addition:
IEC 60601-1-2:2014+AMD1:2020 and IEC 60601-1-6:2010+AMD1:2013+AMD2:2020 apply as modified in
Clauses 202, 206 and 211 respectively. IEC 60601-1-3 and IEC 60601-1-9 do not apply. All other published
collateral standards in the IEC 60601-1 series apply as published.
ISO 80601-2-70:2025(en)
4 Particular standards
Replacement:
In the IEC 60601 series, particular standards specify basic safety and essential performance requirements,
and may modify, replace or delete requirements contained in the general standard and collateral standards
as appropriate for the particular ME equipment under consideration.
A requirement of a particular standard takes priority over the general standard.
For brevity, IEC 60601-1+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 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 “20x”, where x is the final digit(s) 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, 203.4 in this document addresses the content of Clause 4 of the IEC 60601-1-3 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 which 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
3.139, 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, 211 for IEC 60601-
1-11, etc.
The term "this document" is used to make reference to the general standard, 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 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 document.
