Medical electrical equipment - Part 2-87: Particular requirements for basic safety and essential performance of high-frequency ventilators (ISO 80601-2-87:2021)

ISO 80601-2-87 applies to the basic safety and essential performance of a high-frequency ventilator (HFV) in combination with its accessories, hereafter referred to as ME equipment:- intended for use in an environment that provides specialized care for patients whose conditions can be life-threatening and who can require comprehensive care and constant monitoring in a professional healthcare facility; - intended to be operated by a healthcare professional operator;- intended for those patients who need differing levels of support from artificial ventilation including ventilator-dependent patients; and- capable of providing more than 150 inflations/min. There are three principal designations of HFV:- high-frequency percussive ventilation [HFPV, with a typical HFV frequency of (60 to 1 000) HFV inflations/min];- high-frequency jet ventilation [HFJV, with a typical HFV frequency of (100 to 1 500) HFV inflations/min]; and- high-frequency oscillatory ventilation [HFOV, with a typical HFV frequency of (180 to 1200) HFV inflations/min and typically having an active expiratory phase].

Medizinische elektrische Geräte - Teil 2-87: Besondere Festlegungen an die Sicherheit und die wesentlichen Leistungsmerkmale von Hochfrequenz Beatmungsgeräten (ISO 80601-2-87:2021)

Dieses Dokument gilt für die Basissicherheit und die wesentlichen Leistungsmerkmale eines Hochfrequenz Beatmungsgeräts (HFV, en: High Frequency Ventilator) in Kombination mit dessen Zubehör, nachfolgend als ME Gerät bezeichnet, das:
—   für den Gebrauch in einer Umgebung vorgesehen ist, die eine spezielle Pflege für Patienten bietet, deren Zustand lebensgefährlich sein kann und die eine umfassende Pflege sowie ununterbrochene Überwachung in einer professionellen Gesundheitseinrichtung erfordern können;
ANMERKUNG 1   Im Sinne dieses Dokuments wird eine derartige Umgebung eine Intensivpflege Umgebung genannt. Hochfrequenz Beatmungsgeräte für diese Umgebung werden als lebenserhalten angesehen.
ANMERKUNG 2   Für die Anwendung dieses Dokuments kann ein solches Hochfrequenz Beatmungsgerät für den Krankentransport innerhalb einer professionellen Gesundheitseinrichtung eingesetzt werden (d. h. ein Beatmungsgerät sein, das betriebsfähig bei Bewegung ist).
ANMERKUNG 3   Ein Hochfrequenz Beatmungsgerät, das für den Krankentransport innerhalb einer professionellen Gesundheitseinrichtung vorgesehen ist, wird nicht als Beatmungsgerät für eine Umgebung für den Notfalleinsatz betrachtet.
—   für den Betrieb durch einen medizinisch ausgebildeten Bediener vorgesehen ist;
—   für Patienten vorgesehen ist, die unterschiedlich starke Unterstützung durch künstliche Beatmung benötigen, einschließlich vom Gerät abhängiger Patienten;
—   mehr als 150 Aufblähungen/min bereitstellen kann.
Es gibt hauptsächlich drei Bezeichnungen für HFV:
—   perkussive Hochfrequenz Beatmung (HFPV, en: High Frequency Percussive Ventilation, mit einer typischen HFV Frequenz von (60 bis 1 000) HFV Aufblähungen/min);
—   Hochfrequenz Jet Beatmung (HFJV, en: High Frequency Jet Ventilation, mit einer typischen HFV Frequenz von (100 bis 1 500) HFV Aufblähungen/min);
—   Hochfrequenz Oszillations Beatmung (HFOV, en: High Frequency Oscillatory Ventilation, mit einer typischen HFV Frequenz von (180 bis 1 200) HFV Aufblähungen/min und typischerweise einer aktiven Exspirationsphase).
Darüber hinaus können die HFV Bezeichnungen untereinander oder mit einer Beatmung mit einer Frequenz von weniger als 150 Aufblähungen/min kombiniert werden.
* Für Hochfrequenz Beatmungsgeräte wird keine Verwendung von physiologischen geschlossenen Regelsystemen angenommen, es sei denn, es wird eine physiologische Patientenvariable verwendet, um die Einstellungen des Beatmungsgeräts anzupassen.

Medical electrical equipment —
Part 2-87: Particular requirements for basic safety and essential
performance of high-frequency critical care ventilators
201.1 Scope, object and related standards
Clause 1 of IEC 60601-1:2005+AMD1:2012+AMD2:2020 applies, except as follows:
NOTE The general standard is IEC 60601-1:2005+AMD1:2012+AMD2:2020.
201.1.1 * Scope
Replacement:

This document applies to the basic safety and essential performance of a high-frequency ventilator

(HFV) in combination with its accessories, hereafter referred to as ME equipment:

 intended for use in an environment that provides specialized care for patients whose

conditions can be life-threatening and who can require comprehensive care and constant

monitoring in a professional healthcare facility;

NOTE 1 For the purposes of this document, such an environment is referred to as a critical care environment.

High-frequency ventilators for this environment are considered life-sustaining.

NOTE 2 For the purposes of this document, such a high-frequency ventilator can provide transport within a

professional healthcare facility (i.e., be a transit-operable ventilator).

NOTE 3 A high-frequency ventilator intended for use in transport within a professional healthcare facility is

not considered as a ventilator intended for the emergency medical services environment.

 intended to be operated by a healthcare professional operator;

 intended for those patients who need differing levels of support from artificial ventilation

including ventilator-dependent patients; and
 capable of providing more than 150 inflations/min.
There are three principal designations of HFV:

 high-frequency percussive ventilation [HFPV, with a typical HFV frequency of (60 to 1 000)

HFV inflations/min];

 high-frequency jet ventilation [HFJV, with a typical HFV frequency of (100 to 1 500) HFV

inflations/min]; and

 high-frequency oscillatory ventilation [HFOV, with a typical HFV frequency of (180 to 1200)

HFV inflations/min and typically having an active expiratory phase].

---------------------- Page: 13 ----------------------
SIST EN ISO 80601-2-87:2021
ISO 80601-2-87:2021(E)

Additionally, HFV designations can be combined together or with ventilation at rates less than

150 inflations/min.

* A high-frequency ventilator is not considered a physiologic closed loop-control system unless it

uses a physiological patient variable to adjust the ventilation therapy settings.

This document is also applicable to those accessories intended by their manufacturer to be

connected to an HFV breathing system, or to a high-frequency ventilator, where the characteristics

of those accessories can affect the basic safety or essential performance of the high-frequency

ventilator.

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 document are not covered by specific requirements in this document except in

7.2.13 and 8.4.1 of IEC 60601-1:2005.
NOTE 4 Additional information can be found in 4.2 of IEC 60601-1:2005+AMD1:2012.

This document is not applicable to ME equipment that is intended solely to augment the

ventilation of spontaneously breathing patients within a professional healthcare facility.

This document does not specify the requirements for:

 non-high-frequency ventilators or accessories which provide conventional ventilation for use

[23]
in critical care environments, which are given in ISO 80601-2-12 ;.

NOTE 5 An HFV can incorporate conventional critical care ventilator operational modes, in which case ISO 80601-

2-12 is applicable to those modes.

 ventilators or accessories intended for anaesthetic applications, which are given in

[24]
ISO 80601-2-13 ;

 ventilators or accessories intended for the emergency medical services environment, which are

[13]
given in ISO 80601-2-84, the replacement for ISO 10651-3 ;
NOTE 6 An HFV can incorporate EMS ventilator capability.

 ventilators or accessories intended for ventilator-dependent patients in the home healthcare

[26]
environment, which are given in ISO 80601-2-72 ;

 ventilators or accessories intended for home-care ventilatory support devices, which are

[27] [28] [15]
given in ISO 80601-2-79 and ISO 80601-2-80 , the replacements for ISO 10651-6 ;
[25]

 sleep apnoea breathing therapy ME equipment, which are given in ISO 80601-2-70 ;

 bi-level positive airway pressure (bi-level PAP) ME equipment;
 continuous positive airway pressure (CPAP) ME equipment;

 cuirass or “iron-lung” ventilation equipment.

This document is a particular standard in the IEC 60601 series, the IEC 80601 series and the ISO

80601 series.
201.1.2 Object
Replacement:

The object of this document is to establish particular basic safety and essential performance

requirements for a high-frequency ventilator, as defined in 201.3.201, and its accessories.

NOTE 1 Accessories are included because the combination of the high-frequency ventilator and the accessories

needs to be adequately safe. Accessories can have a significant impact on the basic safety or essential performance of

a high-frequency ventilator.

NOTE 2 This document has been prepared to address the relevant essential principles and labelling

guidances of the International Medical Devices Regulators Forum (IMDRF) as indicated in Annex CC.

NOTE 3 This document has been prepared to address the relevant essential principles of safety and performance of

ISO 16142-1:2016 as indicated in Annex DD.

NOTE 4 This document has been prepared to address the relevant general safety and performance requirements

[38]
of European regulation (EU) 2017/745 as indicated in Annex FF.
201.1.3 Collateral standards
Amendment (add after existing text):

This document refers to those applicable collateral standards that are listed in Clause 2 of the

general standard and 201.2 of this document.

IEC 60601-1-2, IEC 60601-1-6 and IEC 60601-1-8 apply as modified in Clauses 202, 206 and 208

[29] [30] [31]

respectively. IEC 60601-1-3 , IEC 60601-1-9 , IEC 60601-1-11 and IEC 60601-1-12 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, including the collateral standards, as appropriate for the

particular ME equipment under consideration, and may add other basic safety or essential

performance requirements.
A requirement of a particular standard takes priority over
IEC 60601-1:2005+AMD1:2012+AMD2:2020 or the collateral standards.

For brevity, IEC 60601-1:2005+AMD1:2012+AMD2:2020 is referred to in this particular

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 those of the general

[29]
IEC 60601-1-3 , etc.

The term “this document” is used to make reference to the general standard, any applicable

collateral standards and this particular document taken together.

Where there is no corresponding clause or subclause in this document, the clause or subclause

of IEC 60601-1:2005+AMD1:2012 or the applicable collateral standard, although possibly not

relevant, applies without modification; where it is intended that any part of

IEC 60601-1:2005+AMD1:2012 or the applicable collateral standard, although possibly relevant,

is not to be applied, a statement to that effect is given in this particular document.

136 Medical Electrical Equipment — Part 2-87: Particular
137 requirements for basic safety and essential performance
138 of high-frequency critical care ventilators
139 201.1 Scope, object and related standards
140 Clause 1 of the general standard applies, except as follows:
141 201.1.1 * Scope
142 Replacement:

143 This document applies to the basic safety and essential performance of a high-frequency

144 ventilator (HFV) in combination with its accessories, hereafter referred to as ME equipment:

145 ⎯ intended for use in an environment that provides specialized care for patients whose

146 conditions can be life-threatening and who can require comprehensive care and

147 constant monitoring in a professional healthcare facility;

148 NOTE 1 For the purposes of this document, such an environment is referred to as a critical care

149 environment. High-frequency ventilators for this environment are considered life-sustaining.

150 NOTE 2 For the purposes of this document, such a high-frequency ventilator can provide transport

151 within a professional healthcare facility (i.e. be a transit-operable ventilator).

152 NOTE 3 A high-frequency ventilator intended for use in transport within a professional healthcare

153 facility is not considered as an ventilator intended for the emergency medical services environment.

154 ⎯ intended to be operated by a healthcare professional operator;

155 ⎯ intended for those patients who need differing levels of support from artificial

156 ventilation including ventilator-dependent patients; and
157 ⎯ capable of providing more than 150 inflations/min.
158 There are three principal designations of HFV:

159 ⎯ high frequency percussive ventilation (HFPV, with a typical HFV frequency of (60 to

160 1 000) HFV inflations/min);

161 ⎯ high frequency jet ventilation (HFJV, with a typical HFV frequency of (100 to 1 500)

162 HFV inflations/min); and

163 ⎯ high frequency oscillatory ventilation (HFOV, with a typical HFV frequency of (180 to

164 1200) HFV inflations/min and typically having an active expiratory phase).

165 Additionally, HFV designations can be combined together or with ventilation at rates less

166 than 150 inflations/min.

167 * A high-frequency ventilator is not considered to utilize physiologic closed loop-control

168 system unless it uses a physiological patient variable to adjust the ventilation therapy

169 settings.

170 This document is also applicable to those accessories intended by their manufacturer to be

171 connected to an HFV breathing system, or to a high-frequency ventilator, where the

172 characteristics of those accessories can affect the basic safety or essential performance of

173 the high-frequency ventilator.

174 If a clause or subclause is specifically intended to be applicable to ME equipment only, or

175 to ME systems only, the title and content of that clause or subclause will say so. If that is

176 not the case, the clause or subclause applies both to ME equipment and to ME systems, as

177 relevant.

178 Hazards inherent in the intended physiological function of ME equipment or ME systems

179 within the scope of this document are not covered by specific requirements in this

180 document except in 7.2.13 and 8.4.1 of IEC 60601-1:2005.

181 NOTE 4 Additional information can be found in 4.2 of IEC 60601-1:2005+AMD1:2012.

182 This document is not applicable to ME equipment that is intended solely to augment the

183 ventilation of spontaneously breathing patients within a professional healthcare facility.

184 This document does not specify the requirements for:

185 ⎯ non-high-frequency ventilators or accessories which provide conventional ventilation

186 for use in critical care environments, which are given in ISO 80601-2-12;.

187 NOTE 5 An HFV can incorporate conventional critical care ventilator operational modes, in which case

188 ISO 80601-2-12 is applicable to those modes.

189 ⎯ ventilators or accessories intended for anaesthetic applications, which are given in

[3]
190 ISO 80601-2-13 ;

191 ⎯ ventilators or accessories intended for the emergency medical services environment,

[4]
192 which are given in ISO 80601-2-84, the future replacement for ISO 10651-3 ;
193 NOTE 6 An HFV can incorporate EMS ventilator capability.

194 ⎯ ventilators or accessories intended for ventilator-dependent patients in the home

[5]
195 healthcare environment, which are given in ISO 80601-2-72 ;

196 ⎯ ventilators or accessories intended for home-care ventilatory support devices, which

[6] [7]
197 are given in ISO 80601-2-79 and ISO 80601-2-80 , the replacements for
[8]

203 This document is a particular standard in the IEC 60601 and IEC/ISO 80601 series of

204 documents.
205 201.1.2 Object
206 Replacement:

207 The object of this document is to establish particular basic safety and essential performance

208 requirements for a high-frequency ventilator, as defined in 201.3.201, and its accessories.

209 NOTE 1 Accessories are included because the combination of the high-frequency ventilator and the

210 accessories needs to be adequately safe. Accessories can have a significant impact on the basic safety or

211 essential performance of a high-frequency ventilator.

212 NOTE 2 This document has been prepared to address the relevant essential principles of safety and

213 performance of ISO 16142-1:2016 as indicated in Annex CC.

214 NOTE 3 This document has been prepared to address the relevant general safety and performance

[10]
215 requirements of European regulation (EU) 2017/745 as indicated in Annex DD.
216 201.1.3 Collateral standards
217 Amendment (add after existing text):

218 This document refers to those applicable collateral standards that are listed in Clause 2 of

219 the general standard and 201.2 of this document.

220 IEC 60601-1-2, IEC 60601-1-6 and IEC 60601-1-8 apply as modified in Clauses 202, 206

[11] [12]
221 and 208 respectively. IEC 60601-1-3 , IEC 60601-1-9 , IEC 60601-1-11 and
[13]

222 IEC 60601-1-12 do not apply. All other published collateral standards in the

223 IEC 60601-1 series apply as published.
224 201.1.4 Particular standards
225 Replacement:

226 In the IEC 60601 series, particular standards may modify, replace or delete requirements

227 contained in the general standard, including the collateral standards, as appropriate for

228 the particular ME equipment under consideration, and may add other basic safety or

229 essential performance requirements.

230 A requirement of a particular standard takes priority over IEC 60601-1:2005 or the

231 collateral standards.

232 For brevity, IEC 60601-1:2005+AMD1:2012 is referred to in this particular document as

233 the general standard. Collateral standards are referred to by their document number.

234 The numbering of clauses and subclauses of this document corresponds to those of the

235 general standard with the prefix “201” (e.g. 201.1 in this document addresses the content

236 of Clause 1 of the general standard) or applicable collateral standard with the prefix “2xx”

237 where xx is the final digits of the collateral standard document number (e.g. 202.4 in this
