INTRODUCTION TO AMENDMENT 2
The second edition of IEC 60601-1-8 was published in 2006 and amended in 2012. Since the
publication of IEC 60601-1-8:2006+A1:2012, the IEC Subcommittee (SC) 62A Secretariat has
been collecting issues from a variety of sources including comments from National Committees.
At the November 2015 meeting of IEC/SC 62A in Kobe, Japan, the subcommittee initiated a
process to identify high-priority issues that need to be considered in an amendment and should
not wait until the third edition of IEC 60601-1-8, which is presently targeted for publication
sometime after 2024.
Those issues selected for inclusion on the final "short list" to be addressed in Amendment 2
were those approved by a 2/3 majority of the National Committees present and voting at the
Frankfurt meeting of SC 62A. At the meeting held on 10 October 2016, 20 items were presented
to the National Committees present. All 20 items received the required 2/3 majority of the
National Committees present and voting and have been included in the "short list" for
consideration in preparing Amendment 2. All remaining issues have been placed on a "long list"
for consideration in the third edition of IEC 60601-1-8.
The "short list" of issues was documented in the design specification for Amendment 2. As
IEC 60601-1-8 was jointly developed with ISO/TC 121/SC 3, the work was assigned to
IEC/SC 62A-ISO/TC 121/SC 3 Joint Working Group (JWG) 2. JWG 2 was directed to consider
each issue described in Clause 6 of the design specification and develop an appropriate
solution for the identified problem. That final solution in this amendment can encompass any
technical solution proposed by the author of the issue or it can involve a different solution
developed by the expert group. The expert group can also have recommended that no change
to the standard was justified by the problem statement.
Because this is an amendment to IEC 60601-1-8:2006, the style in force at the time of
publication of IEC 60601-1-8 has been applied to this amendment. The style specified in
ISO/IEC Directives Part 2:2018 has only been applied when implementing the new style
guidance would not result in additional editorial changes. For example, notes to definitions are
designated as "NOTE" rather than "Note to entry" in Clause 3.
Users of this document should note that when constructing the dated references to specific
elements in a standard, such as definitions, amendments are only referenced if they modified
the text being cited. For example, if a reference is made to a definition that has not been
modified by an amendment, then the reference to the amendment is not included in the dated
reference.

3.38
* ADVISORY
ADVISORY SIGNAL
INFORMATION SIGNAL notifying the OPERATOR of a condition of the PATIENT or ME EQUIPMENT
providing contextual awareness that is intended to improve the clinical workflow or
PATIENT condition, the awareness not being intended as a means of RISK
understanding of the
CONTROL
NOTE 1 A notification that a lab result is available, where the lab result requires immediate clinical action is not an
ADVISORY. It is an ALARM CONDITION.
NOTE 2 A signal associated with an ADVISORY, which is an INFORMATION SIGNAL, is required by this document to be
designed so that an OPERATOR does not confuse it with an ALARM SIGNAL. See 6.3.2.2.2 and 6.3.3.2.
EXAMPLE 1 A notification that it is time to draw the next blood sample.
EXAMPLE 2 A battery status notification that replacement will be needed in a day.

3.44
* CLINICALLY ACTIONABLE
type of ALARM CONDITION for which a panel of experts would agree that OPERATOR action is
necessary to prevent HARM within the timeframe implied by the priority communicated by the
ALARM SYSTEM
NOTE 1 An OPERATOR action can include assessment of a PATIENT or the changing of ALARM LIMITS when they are
inappropriately set for the state of the PATIENT.
NOTE 2 A LOW PRIORITY ALARM CONDITION, which requires action within the timeframe of a MEDIUM PRIORITY or HIGH
PRIORITY timeframe, is considered CLINICALLY ACTIONABLE. A HIGH PRIORITY ALARM CONDITION, which requires action
within the timeframe of a LOW PRIORITY or MEDIUM PRIORITY timeframe, is considered CLINICALLY NONACTIONABLE. In
both cases, the ALARM CONDITION priority was improperly assigned.
NOTE 3 A FALSE POSITIVE ALARM CONDITION is never considered CLINICALLY ACTIONABLE even though an unrelated
OPERATOR action might be required to prevent a future FALSE POSITIVE ALARM CONDITION.
NOTE 4 A CLINICALLY ACTIONABLE ALARM CONDITION is generally considered useful by the OPERATOR.
3.45
* CLINICALLY NONACTIONABLE
type of ALARM CONDITION for which a panel of experts would agree that OPERATOR action is not
expected within a timeframe equal to or shorter than the timeframe implied by its priority
NOTE 1 A LOW PRIORITY ALARM CONDITION, which requires action within the timeframe of a MEDIUM PRIORITY or HIGH
PRIORITY timeframe, is considered CLINICALLY ACTIONABLE. A HIGH PRIORITY ALARM CONDITION, which requires action
within the timeframe of a LOW PRIORITY or MEDIUM PRIORITY timeframe, is considered CLINICALLY NONACTIONABLE. In
both cases, the ALARM CONDITION priority was improperly assigned.
NOTE 2 CLINICALLY NONACTIONABLE ALARM CONDITIONS are considered detrimental to OPERATOR performance and
PATIENT safety.
NOTE 3 ALARM SIGNALS for an ALARM CONDITION of which the OPERATOR is already aware are considered CLINICALLY
NONACTIONABLE.
3.46
COMMUNICATOR
COM
ANNUNCIATOR
function of the ALARM SYSTEM that generates ALARM SIGNALS to notify an OPERATOR (e.g. to the
presence of an ALARM CONDITION)
NOTE 1 A COMMUNICATOR can receive an OPERATOR response.
NOTE 2 An OPERATOR response is not limited to direct OPERATOR action.
NOTE 3 See Figure 2.
3.47
DISTRIBUTED ALARM SYSTEM WITH OPERATOR CONFIRMATION
CDAS
DISTRIBUTED ALARM SYSTEM that includes the capability to receive an OPERATOR response
3.48
* DISTRIBUTED INFORMATION SYSTEM ABOUT ALARM CONDITIONS
DIS
system that involves more than one item of equipment in a ME SYSTEM intended to provide
information about ALARM CONDITIONS but does not guarantee delivery of that information
NOTE 1 A DISTRIBUTED INFORMATION SYSTEM ABOUT ALARM CONDITIONS is not intended to notify OPERATORS of the
existence of an ALARM CONDITION as a RISK CONTROL measure. A DISTRIBUTED INFORMATION SYSTEM ABOUT ALARM
CONDITIONS is intended to provide information about an ALARM CONDITION while the OPERATOR is aware of the
existence of the ALARM CONDITION by an ALARM SYSTEM.
NOTE 2 A DISTRIBUTED INFORMATION SYSTEM ABOUT ALARM CONDITIONS is not intended for confirmed delivery of
ALARM CONDITIONS.

NOTE 2 An INTEGRATOR can send the acceptance of responsibility from a COMMUNICATOR to a SOURCE.
NOTE 3 See Figure 2.
3.50
* NUISANCE ALARM SIGNAL
ALARM SIGNAL for which a panel of experts would agree that the HARM associated with the ALARM
SIGNAL is greater than the benefit associated with action resulting from the ALARM SIGNAL
NOTE 1 A NUISANCE ALARM SIGNAL contributes to ALARM FATIGUE.
NOTE 2 A NUISANCE ALARM SIGNAL can arise from a FALSE POSITIVE ALARM CONDITION.
NOTE 3 A NUISANCE ALARM SIGNAL can arise from a CLINICALLY NONACTIONABLE ALARM CONDITION.
NOTE 4 A NUISANCE ALARM SIGNAL can cause an inappropriate OPERATOR action.
EXAMPLE Causing the OPERATOR to set ALARM LIMITS to inappropriate settings.
NOTE 5 An ALARM SIGNAL that unnecessarily irritates or startles the PATIENT or OPERATOR can be a NUISANCE ALARM
SIGNAL.

24 _____________
25 Note encadrée 1: Étant donné l’ampleur des modifications apportées par cet amendement, il a
26 été demandé aux Comités nationaux d’indiquer s’ils soutiendraient la publication finale en tant
27 que nouvelle édition de l’IEC 60601-1-8 plutôt qu’en tant que deuxième amendement tel qu’il a
28 été initialement prévu. Parmi les Comités nationaux qui ont répondu, le Comité national
29 allemand est fermement opposé à l’idée d’une nouvelle édition tandis que ceux de la Finlande et
30 de l’Afrique du Sud ont estimé qu’une nouvelle édition serait acceptable. À mesure que le projet
31 se poursuit, il convient que les Comités nationaux prennent en compte la section 2.10.3 des
32 directives ISO/IEC:
33 « Au stade approbation (voir 2.7), le Secrétaire général doit décider, en concertation avec le
34 secrétariat du comité technique ou du sous-comité, et en gardant à l'esprit à la fois les
35 conséquences financières pour l'organisation et les intérêts des utilisateurs de la Norme
36 internationale, s'il convient de publier un amendement ou une nouvelle édition de la Norme
37 internationale incorporant l'amendement. (Voir aussi 2.10.4.) »
38 En règle générale, si un amendement fait plus de 10 pages ou 15 % de la publication de base,
39 selon la plus petite des deux valeurs, il est d’usage que le Bureau central de l’IEC publie une
40 nouvelle édition complète plutôt que l’amendement.

42 INTRODUCTION À L’AMENDEMENT 2
43 La deuxième édition de l‘IEC 60601-1-8 a été publiée en 2006 et amendée en 2012. Depuis la
44 publication de l’IEC 60601-1-8:2006/AMD1:2012, le Secrétariat du sous-comité (SC) 62A a
45 recueilli les préoccupations de différentes sources, y compris les commentaires des Comités
46 nationaux. Lors de la réunion du SC 62A de l’IEC en novembre 2015 à Kobe, au Japon, le
47 sous-comité a lancé un processus visant à identifier les questions hautement prioritaires qu’il y
48 a lieu de prendre en considération dans l’Amendement 2 et qu’il convient de traiter avant la
49 troisième édition, dont la publication est prévue peu après 2024.
50 Comme cela est spécifié au point 2 de la Résolution 1 de Kobe (62A/1069/RM), pour qu’une
51 question soit incluse dans la « sélection réduite » finale et soit traitée dans l’Amendement 2, la
52 question doit avoir été approuvée à la majorité des deux tiers des Comités nationaux présents
53 et votant à la réunion du SC 62A à Francfort. 20 points ont été présentés aux Comités nationaux
54 présents à la réunion du 10 octobre 2016. Les 20 points ont tous recueilli la majorité exigée des
55 2/3 des Comités nationaux présents et votants et ont été inclus dans la « sélection réduite »
56 pour examen lors de l’élaboration de l’Amendement 2. Toutes les questions restantes ont été
57 inscrites sur une « liste plus large » pour examen lors de la troisième édition.
58 La « sélection réduite » de questions a fait l’objet de documentation dans la Spécification de
59 conception de l’Amendement 2 (62A/1170/INF). L’IEC 60601-1-8 ayant été développée
60 conjointement avec le SC 3 du TC 121 de l’ISO, les travaux ont été confiés au Groupe de travail
61 commun (JWG) 2 IEC/SC 62A-ISO/TC 121/SC 3. Le JWG 2 a été chargé d’examiner les
62 questions décrites à l’Article 6 des spécifications de conception et de proposer une solution
63 appropriée au problème identifié. La solution finale proposée dans cet amendement peut inclure
64 les solutions techniques proposées par l’auteur de la question soulevée ou une solution
65 différente élaborée par le groupe d’experts. Le groupe d’experts a également pu indiquer que
66 l’énoncé du problème ne justifiait aucune modification de la norme.
67 Étant donné qu’il s’agit d’un amendement à l’édition 2006 de l’IEC 60601-1-8, le style en vigueur
68 à la date de publication de l’IEC 60601-1-8 a été appliqué au présent amendement. Le style
69 spécifié dans les directives ISO/IEC Partie 2:2018 n’a été appliqué que lorsque l’application du
70 nouveau guide stylistique n’entraînait pas de modifications rédactionnelles supplémentaires. Par
71 exemple, les notes aux définitions dans l’Article 3 sont désignées par « NOTE » plutôt que par
72 « Note à l’article ».
73 Il convient que les utilisateurs du présent document notent qu’à l’insertion des références
74 datées à des éléments spécifiques (aux définitions, par exemple) dans une norme, les
75 amendements ne sont référencés que s’ils modifient le texte cité. Par exemple, si une référence
76 est faite à une définition qui n’a pas été modifiée par un amendement, la référence à
77 l’amendement n’est pas incluse dans la référence datée.

221 l'OPERATEUR est nécessaire pour empêcher que des DOMMAGES ne surviennent dans les délais
222 prévus par la priorité attribuée par le SYSTEME D’ALARME
223 NOTE 1 Une action de l’OPERATEUR peut consister à évaluer un PATIENT ou à modifier les LIMITES D’ALARME
224 lorsqu'elles sont définies de manière inappropriée pour l’état du PATIENT.
225 NOTE 2 Une CONDITION D’ALARME DE FAIBLE PRIORITE, qui exige une action dans les délais impartis d’une PRIORITE
226 MOYENNE ou d’une PRIORITE ELEVEE, est considérée comme étant CLINIQUEMENT REALISABLE. Une CONDITION D’ALARME
227 DE PRIORITE ELEVEE, qui exige une action dans les délais impartis d’une FAIBLE PRIORITE ou d’une PRIORITE MOYENNE,
228 est considérée comme étant cliniquement non réalisable. Dans les deux cas, la priorité de la CONDITION D’ALARME n’a
229 pas été correctement attribuée.
230 NOTE 3 Une FAUSSE CONDITION D’ALARME POSITIVE n'est jamais considérée comme étant CLINIQUEMENT REALISABLE,
231 même si une action indépendante de l’OPERATEUR peut être exigée pour éviter une future FAUSSE CONDITION D’ALARME
232 POSITIVE.

234 l’OPERATEUR.
235 3.44
236 * CLINIQUEMENT NON REALISABLE
237 type de CONDITION D’ALARME pour lequel un groupe d’experts convient que l’action de
238 l'OPERATEUR n’est pas attendue dans un délai inférieur ou égal au délai prévu par sa priorité
239 NOTE 1 Une CONDITION D’ALARME DE FAIBLE PRIORITE, qui exige une action dans les délais impartis d’une priorité
240 moyenne ou d’une priorité élevée, est considérée comme étant CLINIQUEMENT REALISABLE. Une CONDITION D’ALARME DE
241 PRIORITE ELEVEE, qui exige une action dans les délais impartis d’une FAIBLE PRIORITE ou d’une PRIORITE MOYENNE, est
242 considérée comme étant CLINIQUEMENT NON REALISABLE. Dans les deux cas, la priorité de la CONDITION D’ALARME n’a
243 pas été correctement attribuée.
244 NOTE 2 Les conditions d’alarme CLINIQUEMENT NON REALISABLES sont considérées comme étant préjudiciables aux
245 performances de l’OPERATEUR et à la sécurité du PATIENT.
246 NOTE 3 Les SIGNAUX D’ALARME d’une CONDITION D’ALARME dont l’OPERATEUR a déjà connaissance sont considérés
247 comme CLINIQUEMENT NON REALISABLES.
248 3.45

262 * SYSTEME D’INFORMATION REPARTI SUR LES CONDITIONS D’ALARME
263 DIS
264 système qui implique plus d’un élément d’équipement d’un SYSTEME EM destiné à fournir des
265 informations sur les CONDITIONS D’ALARME, mais ne garantit pas la transmission de ces
266 informations
267 NOTE 1 Un SYSTEME D’INFORMATION REPARTI SUR LES CONDITIONS D’ALARME n'est pas destiné à informer les
268 OPERATEURS de l'existence d'une CONDITION D’ALARME à titre de mesure de MAITRISE DU RISQUE. Un SYSTEME
269 D’INFORMATION REPARTI SUR LES CONDITIONS D’ALARME vise à fournir de l’information sur une CONDITION D’ALARME
270 pendant que l’OPERATEUR est informé de l’existence de cette CONDITION D’ALARME par un SYSTEME D’ALARME.
271 NOTE 2 Un SYSTEME D’INFORMATION REPARTI SUR LES CONDITIONS D’ALARME n'est pas destiné à permettre l’existence

282 conséquent, vers l’OPERATEUR.
283 NOTE 2 Un INTEGRATEUR peut transmettre l’acceptation de la responsabilité d’un COMMUNICATEUR à une SOURCE.
284 3.49
285 * SIGNAL D’ALARME NUISIBLE
286 SIGNAL D’ALARME pour lequel un groupe d’experts conviendrait que les DOMMAGES associés à ce
287 SIGNAL D’ALARME sont supérieurs aux avantages associés à une action résultant du SIGNAL
288 D’ALARME
289 NOTE 1 Un SIGNAL D’ALARME NUISIBLE contribue à la FATIGUE LIEE AUX ALARMES.
290 NOTE 2 Un SIGNAL D’ALARME NUISIBLE peut provenir d’une CONDITION D’ALARME CLINIQUEMENT NON REALISABLE.
291 NOTE 3 Un SIGNAL D’ALARME NUISIBLE peut provoquer une action inappropriée de l’OPERATEUR.

INTRODUCTION TO AMENDMENT 2
The second edition of IEC 60601-1-8 was published in 2006 and amended in 2012. Since the
publication of IEC 60601-1-8:2006+A1:2012, the IEC Subcommittee (SC) 62A Secretariat has
been collecting issues from a variety of sources including comments from National Committees.
At the November 2015 meeting of IEC/SC 62A in Kobe, Japan, the subcommittee initiated a
process to identify high-priority issues that need to be considered in an amendment and should
not wait until the third edition of IEC 60601-1-8, which is presently targeted for publication
sometime after 2024.
Those issues selected for inclusion on the final "short list" to be addressed in Amendment 2
were those approved by a 2/3 majority of the National Committees present and voting at the
Frankfurt meeting of SC 62A. At the meeting held on 10 October 2016, 20 items were presented
to the National Committees present. All 20 items received the required 2/3 majority of the
National Committees present and voting and have been included in the "short list" for
consideration in preparing Amendment 2. All remaining issues have been placed on a "long list"
for consideration in the third edition of IEC 60601-1-8.
The "short list" of issues was documented in the design specification for Amendment 2. As
IEC 60601-1-8 was jointly developed with ISO/TC 121/SC 3, the work was assigned to
IEC/SC 62A-ISO/TC 121/SC 3 Joint Working Group (JWG) 2. JWG 2 was directed to consider
each issue described in Clause 6 of the design specification and develop an appropriate
solution for the identified problem. That final solution in this amendment can encompass any
technical solution proposed by the author of the issue or it can involve a different solution
developed by the expert group. The expert group can also have recommended that no change
to the standard was justified by the problem statement.
Because this is an amendment to IEC 60601-1-8:2006, the style in force at the time of
publication of IEC 60601-1-8 has been applied to this amendment. The style specified in
ISO/IEC Directives Part 2:2018 has only been applied when implementing the new style
guidance would not result in additional editorial changes. For example, notes to definitions are
designated as "NOTE" rather than "Note to entry" in Clause 3.
Users of this document should note that when constructing the dated references to specific
elements in a standard, such as definitions, amendments are only referenced if they modified
the text being cited. For example, if a reference is made to a definition that has not been
modified by an amendment, then the reference to the amendment is not included in the dated
reference.

3.38
* ADVISORY
ADVISORY SIGNAL
INFORMATION SIGNAL notifying the OPERATOR of a condition of the PATIENT or ME EQUIPMENT
providing contextual awareness that is intended to improve the clinical workflow or
PATIENT condition, the awareness not being intended as a means of RISK
understanding of the
CONTROL
NOTE 1 A notification that lab result is available, where the lab result requires immediate clinical action is not an
ADVISORY. It is an ALARM CONDITION.
NOTE 2 A signal associated with an ADVISORY, which is an INFORMATION SIGNAL, is required by this document to be
designed so that an OPERATOR does not confuse it with an ALARM SIGNAL. See 6.3.2.2.2 and 6.3.3.2.
EXAMPLE 1 A notification that it is time to draw the next blood sample.
EXAMPLE 2 A battery status notification that replacement will be needed in a day.

situation wherein the presence of frequent ALARM SIGNALS desensitizes an OPERATOR to an
ALARM SIGNAL
NOTE 1 A desensitized OPERATOR can fail to perceive, recognize or act on an ALARM SIGNAL.
NOTE 2 The response of a desensitized OPERATOR can be inadequate, delayed or non-existent.
NOTE 3 ALARM FLOOD can cause ALARM FATIGUE.
3.40
ALARM FLOOD
situation wherein OPERATORS receive more ALARM SIGNALS in a time period than they can
manage appropriately
NOTE See [56], [57].

CONDITIONS", "equipment-user advisory signals" with "ADVISORIES" and deleted "patient
related".]
3.42
AUDITORY ICON
sound that creates a strong semantic link to the category it represents
NOTE 1 An AUDITORY ICON is typically a real-world sound or mimics a real-world sound.
NOTE 2 An AUDITORY ICON can aid in locating the COMMUNICATOR and the SOURCE type.
3.43
AUDITORY POINTER
sound that attracts attention, denotes the priority and aids in localization of the COMMUNICATOR

3.44
* CLINICALLY ACTIONABLE
type of ALARM CONDITION for which a panel of experts would agree that OPERATOR action is
necessary to prevent HARM within the timeframe implied by the priority communicated by the
ALARM SYSTEM
NOTE 1 An OPERATOR action can include assessment of a PATIENT or the changing of ALARM LIMITS when they are
inappropriately set for the state of the PATIENT.
NOTE 2 A LOW PRIORITY ALARM CONDITION, which requires action within the timeframe of a MEDIUM PRIORITY or HIGH
PRIORITY timeframe, is considered CLINICALLY ACTIONABLE. A HIGH PRIORITY ALARM CONDITION, which requires action
within the timeframe of a LOW PRIORITY or MEDIUM PRIORITY timeframe, is considered CLINICALLY NONACTIONABLE. In
both cases, the ALARM CONDITION priority was improperly assigned.
NOTE 3 A FALSE POSITIVE ALARM CONDITION is never considered CLINICALLY ACTIONABLE even though an unrelated
OPERATOR action might be required to prevent a future FALSE POSITIVE ALARM CONDITION.
NOTE 4 A CLINICALLY ACTIONABLE ALARM CONDITION is generally considered useful by the OPERATOR.
3.45
* CLINICALLY NONACTIONABLE
type of ALARM CONDITION for which a panel of experts would agree that OPERATOR action is not
expected within a timeframe equal to or shorter than the timeframe implied by its priority
NOTE 1 A LOW PRIORITY ALARM CONDITION, which requires action within the timeframe of a MEDIUM PRIORITY or HIGH
PRIORITY timeframe, is considered CLINICALLY ACTIONABLE. A HIGH PRIORITY ALARM CONDITION, which requires action
within the timeframe of a LOW PRIORITY or MEDIUM PRIORITY timeframe, is considered CLINICALLY NONACTIONABLE. In
both cases, the ALARM CONDITION priority was improperly assigned.
NOTE 2 CLINICALLY NONACTIONABLE ALARM CONDITIONS are considered detrimental to OPERATOR performance and
PATIENT safety.
NOTE 3 ALARM SIGNALS for an ALARM CONDITION of which the OPERATOR is already aware are considered CLINICALLY
NONACTIONABLE.
3.46
COMMUNICATOR
COM
ANNUNCIATOR
function of the ALARM SYSTEM that generates ALARM SIGNALS to notify an OPERATOR (e.g. the
presence of an ALARM CONDITION)
NOTE 1 A COMMUNICATOR can receive an OPERATOR response.
NOTE 2 An OPERATOR response is not limited to direct OPERATOR action.
NOTE 3 See Figure 2.
3.47
DISTRIBUTED ALARM SYSTEM WITH OPERATOR CONFIRMATION
CDAS
DISTRIBUTED ALARM SYSTEM that includes the capability to receive an OPERATOR response
3.48
* DISTRIBUTED INFORMATION SYSTEM ABOUT ALARM CONDITIONS
DIS
system that involves more than one item of equipment in a ME SYSTEM intended to provide
information about ALARM CONDITIONS but does not guarantee delivery of that information
NOTE 1 A disTRIBUTED INFORMATION SYSTEM ABOUT ALARM CONDITIONS is not intended to notify OPERATORS of the
existence of an ALARM CONDITION as a RISK CONTROL measure. A DISTRIBUTED INFORMATION SYSTEM ABOUT ALARM
CONDITIONS is intended to provide information about an ALARM CONDITION while the OPERATOR is aware of the
existence of the ALARM CONDITION by an ALARM SYSTEM.
NOTE 2 A DISTRIBUTED INFORMATION SYSTEM ABOUT ALARM CONDITIONS is not intended for confirmed delivery of
ALARM CONDITIONS.

SOURCES or handles the communication between those SOURCES and COMMUNICATORS
from
NOTE 1 An INTEGRATOR can direct or redirect an ALARM CONDITION to another COMMUNICATOR and hence OPERATOR.
NOTE 2 An INTEGRATOR can send the acceptance of responsibility from a COMMUNICATOR to a SOURCE.
NOTE 3 See Figure 2.
3.50
* NUISANCE ALARM SIGNAL
ALARM SIGNAL for which a panel of experts would agree that the HARM associated with the ALARM
SIGNAL is greater than the benefit associated with action resulting from the ALARM SIGNAL
NOTE 1 A NUISANCE ALARM SIGNAL contributes to ALARM FATIGUE.
NOTE 2 A NUISANCE ALARM SIGNAL can arise from a FALSE POSITIVE ALARM CONDITION.
NOTE 3 A NUISANCE ALARM SIGNAL can arise from a CLINICALLY NONACTIONABLE ALARM CONDITION.
NOTE 4 A NUISANCE ALARM SIGNAL can cause an inappropriate OPERATOR action.
EXAMPLE Causing the OPERATOR to set ALARM LIMITS to inappropriate settings.
NOTE 5 An ALARM SIGNAL that unnecessarily irritates or startles the PATIENT or OPERATOR can be a NUISANCE ALARM
SIGNAL.
3.51

to a COMMUNICATOR or transfers an ALARM CONDITION to another COMMUNICATOR
NOTE See Figure 2.
3.52
RESPONSIBILITY ACCEPTED
state created by an OPERATOR response accepting ownership for addressing an ALARM
CONDITION
NOTE 1 A RESPONSIBILITY ACCEPTED can be used to initiate an ALARM SIGNAL inactivation state.
NOTE 2 See Figure 2.
3.53
RESPONSIBILITY REJECTED
state created by an OPERATOR response rejecting ownership for addressing an ALARM CONDITION
NOTE 1 A RESPONSIBILITY REJECTED can be used to initiate an ESCALATION or REDIRECTION.
NOTE 2 See Figure 2.
3.54
RESPONSIBILITY UNDEFINED
state, automatically initiated when neither a RESPONSIBILITY ACCEPTED nor RESPONSIBILITY
REJECTED is received within a specified period, which indicates that an OPERATOR is not
responding
NOTE 1 RESPONSIBILITY UNDEFINED is not used as an indication that the COMMUNICATOR and INTEGRATOR cannot
communicate.
