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

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 [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
