Foreword
ISO (the International Organization for Standardization) and IEC (the International
Electrotechnical Commission) form the specialized system for worldwide standardization.
National bodies that are members of ISO or IEC participate in the development of International
Standards through technical committees established by the respective organization to deal with
particular fields of technical activity. ISO and IEC technical committees collaborate in fields of
mutual interest. Other international organizations, governmental and non-governmental, in
liaison with ISO and IEC, also take part in the work.
The procedures used to develop this document and those intended for its further maintenance
are described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria
needed for the different types of document should be noted. This document was drafted in
accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the
subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such
patent rights. Details of any patent rights identified during the development of the document will
be in the Introduction and/or on the ISO list of patent declarations received (see
www.iso.org/patents) or the IEC list of patent declarations received (see http://patents.iec.ch).
Any trade name used in this document is information given for the convenience of users and does
not constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see
www.iso.org/iso/foreword.html.
This document was prepared jointly by Technical Committee ISO/TC 121, Anaesthetic and
respiratory equipment, Subcommittee SC 3, Respiratory devices and related equipment used for
patient care, and Technical Committee IEC/TC 62, Electrical equipment in medical practice,
Subcommittee SC 62D, Electromedical equipment, in collaboration with the European Committee
for Standardization (CEN) Technical Committee CEN/TC 215, Respiratory and anaesthetic
equipment, in accordance with the Agreement on technical cooperation between ISO and CEN
(Vienna Agreement).

Introduction
In this document, the following print types are used:
– Requirements and definitions: roman type;
– Instructions, test specifications and terms defined in Clause 3 of the general standard, in this
document or as noted: italic type;
– Informative material appearing outside of tables, such as notes, examples and references: in smaller
type. Normative text of tables is also in a smaller type.
In referring to the structure of this document, the term
– “clause” means one of the four numbered divisions within the table of contents, inclusive of
all subdivisions (e.g. Clause 201 includes subclauses 201.7, 201.8, etc.);
– “subclause” means a numbered subdivision of a clause (e.g. 201.7, 201.8 and 201.9 are all
subclauses of Clause 201).
References to clauses within this document are preceded by the term “Clause” followed by the
clause number. References to subclauses within this document are by number only.
In this document, the conjunctive “or” is used as an “inclusive or” so a statement is true if any
combination of the conditions is true.
For the purposes of this document, the auxiliary verb:
– “shall” means that conformance with a requirement or a test is mandatory for conformance
with this document;
– “should” means that conformance with a requirement or a test is recommended but is not
mandatory for conformance with this document;
– “may” is used to describe permission (e.g. a permissible way to achieve conformance with a
requirement or test);
– "can" is used to describe a possibility or capability; and
– "must" is used to express an external constraint.
Annex C contains a guide to the marking and labelling requirements in this document.
Annex D contains a summary of the symbols referenced in this document.
An asterisk (*) as the first character of a title or at the beginning of a paragraph or table title
indicates that there is guidance or rationale related to that item in Annex AA.

INTERNATIONAL STANDARD ISO 80601-2-87:2021(E)
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].
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-freque
