Medical electrical equipment - Part 2-4: Particular requirements for basic safety and essential performance of cardiac defibrillators

This International Standard applies to the BASIC SAFETY and ESSENTIAL PERFORMANCE of CARDIAC DEFIBRILLATORS, hereafter referred to as ME EQUIPMENT. 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. This particular standard does not apply to implantable defibrillators, remote control DEFIBRILLATORS, external transcutaneous pacemakers, or separate stand-alone cardiac monitors (which are standardized by IEC 60601-2-27). Cardiac monitors which use separate ECG monitoring electrodes are not within the scope of this standard unless they are used as the sole basis for AED rhythm recognition detection or beat detection for synchronized cardioversion. Defibrillation waveform technology is evolving rapidly. Published studies indicate that the effectiveness of waveforms varies. The choice of a particular waveform including waveshape, delivered energy, efficacy, and safety has been specifically excluded from the scope of this standard. However, due to the critical importance of the therapeutic waveform, comments have been added to the rationale which addresses considerations in waveform selection.

Appareils électromédicaux - Partie 2-4: Exigences particulières pour la sécurité de base et les performances essentielles pour les défibrillateurs cardiaques

La CEI 60601-2-4:2010 établit des exigences particulières de sécurité de base et de performances essentielles pour les défibrillateurs cardiaques. Cette troisième édition annule et remplace la deuxième édition publiée en 2002. La présente édition constitue une révision technique dont la structure est alignée sur la CEI 60601-1:2005, et est destinée à mettre en oeuvre la décision du SC 62A de la CEI selon laquelle la structure de numérotation des articles des normes particulières rédigées selon la CEI 60601-1:2005 respecterait la forme spécifiée dans les directives ISO/CEI, partie 2:2004. Cette troisième édition est destinée à mettre à jour la présente norme particulière par rapport à la troisième édition de la norme générale par une nouvelle mise en forme et des modifications techniques.

Medicinska električna oprema - 2-4. del: Posebne zahteve za osnovno varnost in bistvene lastnosti srčnih defibrilatorjev

Ta mednarodni standard velja za OSNOVNO VARNOST in BISTVENE LASTNOSTI SRČNIH DEFIBLIRATORJEV, v nadaljevanju ME OPREME. Če bo točka ali podtočka izrecno namenjena samo uporabi za ME OPREMO ali samo za ME SISTEME, bosta naslov in vsebina te točke ali podtočke to tudi navedla. Sicer točka in podtočka veljata za ustrezno ME OPREMO in ME SISTEME. NEVARNOSTI, ki so del fiziološkega delovanja ME OPREME ali ME SISTEMOV v okviru uporabe tega standarda, niso zajete s posebnimi zahtevami tega standarda, razen v točkah 7.2.13 in 8.4.1 splošnega standarda. Ta določeni standard ne velja za vsajene defibrilatorje, DEFIBLIRATORJE z daljinskim upravljanjem, zunanje transkutane srčne spodbujevalnike ali ločene samostojne srčne monitorje (ki so standardizirani z IEC 60601-2-27). Srčni monitorji, ki uporabljajo ločene elektrode ECG za spremljanje, niso v okviru uporabe tega standarda, razen če se uporabljajo izključno za zaznavo prepoznave ritma AED ali zaznave utripa za sinhronizirano kardioverzijo. Tehnologija defibrilatorskih valovnih oblik se hitro razvija. Objavljene študije navajajo, da se učinkovitost valovnih oblik razlikuje. Izbira določene valovne oblike, vključno z obliko vala, dobavljeno energijo, učinkovitostjo in varnostjo, je bila izrecno izključena iz uporabe tega standarda. Vendar so bili zaradi kritične pomembnosti terapevtske valovne oblike utemeljitvi, ki obravnava razloge za valovno obliko in njeno izbiro, dodani komentarji.

Part 2-4: Particular requirements for the basic safety
and essential performance of cardiac defibrillators


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 60601-2-4 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 2002. This edition
constitutes a technical revision, revised to structurally align it with IEC 60601-1:2005 and to
implement the decision of IEC SC 62A that the clause numbering structure of particular
standards written to IEC 60601-1:2005 would adhere to the form specified in ISO/IEC
Directives, Part 2:2004. 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 principle technical changes are as follows:
· 201.8.8.3, test 4: added additional test options;

NOTE See also 4.2 of the general standard.
This particular standard does not apply to implantable defibrillators, remote control
DEFIBRILLATORS, external transcutaneous pacemakers, or separate stand-alone cardiac
2
monitors (which are standardized by IEC 60601-2-27 [2] ). Cardiac monitors which use
separate ECG monitoring electrodes are not within the scope of this standard unless they are
used as the sole basis for AED rhythm recognition detection or beat detection for
synchronized cardioversion.
Defibrillation waveform technology is evolving rapidly. Published studies indicate that the
effectiveness of waveforms varies. The choice of a particular waveform including waveshape,
delivered energy, efficacy, and safety has been specifically excluded from the scope of this
standard.
However, due to the critical importance of the therapeutic waveform, comments have been
added to the rationale which addresses considerations in waveform selection.
201.1.2 Object
Replacement:
The object of this particular standard is to establish particular BASIC SAFETY and ESSENTIAL
PERFORMANCE requirements for cardiac defibrillators as defined in 201.3.202.

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 applies as modified in Clause 202. 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 IEC 60601-1-2 collateral
standard, 203.4 in this particular standard 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 particular standard.
"Addition" means tha
