Elle s'applique aux moniteurs transcutanés utilisés sur des adultes, des enfants et des nouveau-nés, et elle inclut l'utilisation de ces dispositifs dans la surveillance f tale pendant l'accouchement. La CEI 60601-2-23:2011 ne s'applique pas aux oxymètres à hémoglobine saturée ou aux dispositifs appliqués sur des surfaces du corps autres que la peau (par exemple conjonctive, muqueuse). Cette troisième édition annule et remplace la deuxième édition publiée en 1999 et constitue une révision technique. La présente édition de la CEI 60601-2-23 a été mise à jour de façon à correspondre structurellement à l'édition 2005 de la CEI 60601-1.

Medicinska električna oprema - 2-23. del: Posebne zahteve za osnovno varnost in bistvene lastnosti opreme za skozikožno nadzorovanje delnega (parcialnega) krvnega tlaka

IEC 60601-2-23:2011 se uporablja za osnovno varnost in bistvene lastnosti opreme za skozikožno nadzorovanje delnega (parcialnega) krvnega tlaka. Uporablja se za monitorje za skozikožno nadzorovanje pri zdravljenju odraslih, otrok in novorojenčkov ter vključuje uporabo teh naprav pri nadzoru ploda med porodom. IEC 60601-2-23:2011 se ne uporablja za oksimetre, s katerimi se meri nasičenost kisika v krvi, ali naprave za uporabo na telesnih površinah, ki jih ne pokriva koža (npr. veznica, sluznica). Ta tretja izdaja razveljavlja in nadomešča drugo izdajo, objavljeno leta 1999, in predstavlja tehnično popravljeno izdajo. Ta izdaja standarda IEC 60601-2-23 je bila revidirana in strukturno usklajena z izdajo standarda IEC 60601-1:2005.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International standard IEC 60601-2-23 has been prepared by IEC subcommittee 62D:
Electromedical equipment, of IEC technical committee 62: Electrical equipment in medical
practice.
This third edition cancels and replaces the second edition published in 1999 and constitutes a
technical revision. This edition of IEC 60601-2-23 was revised to align structurally with the
2005 edition of IEC 60601-1.

INTRODUCTION
This particular standard concerns the BASIC SAFETY and ESSENTIAL PERFORMANCE of
TRANSCUTANEOUS PARTIAL PRESSURE MONITORING EQUIPMENT. It amends and supplements
IEC 60601-1 (third edition, 2005): Medical electrical equipment – Part 1: General
requirements for basic safety and essential performance, hereinafter referred to as the
general standard.
The aim of this third edition is to bring this particular standard up to date with reference to the
third edition of the general standard through reformatting and technical changes.
The requirements of this particular standard take priority over those of the general standard.
A “General guidance and rationale” for the more important requirements of this particular
standard is included in Annex AA. It is considered that knowledge of the reasons for these
requirements will not only facilitate the proper application of the standard but will, in due
course, expedite any revision necessitated by changes in clinical practice or as a result of
developments in technology. However, Annex AA does not form part of the requirements of
this Standard.

Part 2-23: Particular requirements for the basic safety and
essential performance of transcutaneous partial
pressure monitoring equipment



201.1 Scope, object and related standards
1
Clause 1 of the general standard applies, except as follows:
201.1.1 * Scope
Replacement:
This International Standard applies to the BASIC SAFETY and ESSENTIAL PERFORMANCE of
TRANSCUTANEOUS PARTIAL PRESSURE MONITORING EQUIPMENT as defined in 201.3.63 and
ME EQUIPMENT, whether this ME EQUIPMENT is stand alone or part of a
hereinafter referred to as
system.
This standard applies to transcutaneous monitors used with adults, children and neonates,
and it includes the use of these devices in foetal monitoring during birth.
This standard does not apply to haemoglobin saturation oximeters or to devices applied to
surfaces of the body other than the skin (for example conjunctiva, mucosa).
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.
NOTE See also 4.2 of the General Standard.
201.1.2 Object
Replacement:
The object of this particular standard is to establish BASIC SAFETY and
ESSENTIAL PERFORMANCE requirements for TRANSCUTANEOUS PARTIAL PRESSURE MONITORING
EQUIPMENT as defined in 201.3.63.
201.1.3 Collateral standards
Addition:
This particular standard refers to those applicable collateral standards that are listed in
Clause 2 of the general standard and Clause 201.2 of this particular standard.

IEC 60601-1-2:2007 and IEC 60601-1-8:2006 apply as modified in Clauses 202 and 208
respectively. IEC 60601-1-3 and IEC 60601-1-10 do 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 and collateral standards as appropriate for the particular ME
EQUIPMENT under consideration, and may add other BASIC SAFETY and ESSENTIAL PERFORMANCE
requirements.
A requirement of a particular standard takes priority over the general standard.
For brevity, IEC 60601-1 is referred to in this particular standard as the general standard.
Collateral standards are referred to by their document number.
The numbering of clauses and subclauses of this particular standard corresponds to that of
the general standard with the prefix “201” (e.g. 201.1 in this standard 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
particular standard addresses the content of Clause 4 of the 60601-1-2 collateral standard,
203.4 in this particular standard addresses the content of Clause 4 of the 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 particular standard.
"Addition" means that the text of this particular standard 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 particular standard.
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 standard 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 standard" is used to make reference to the general standard, any applicable
collateral standards and this particular standard taken together.
