CSA C22.2 NO. 80601-2-87:23

CSA Preface 

This is the first edition of CSA C22.2 No. 80601-2-87, Medical electrical equipment — Part 2-87: Particular requirements for basic safety and essential performance of high-frequency ventilators, which is an adoption, with Canadian deviations, of the identically titled ISO (International Organization for Standardization) Standard 80601-2-87 (first edition, 2021-04). It is one in a series of Standards issued by CSA Group under Part II of the Canadian Electrical Code. For brevity, this Standard will be referred to as "CSA C22.2 No. 80601-2-87" throughout. This Standard is intended to be used in conjunction with CAN/CSA-C22.2 No. 60601-1:14, Medical electrical equipment — Part 1: General requirements for basic safety and essential performance (adopted IEC Standard 60601-1:2005, edition 3.2, with Canadian deviations). This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard. This Standard was reviewed for Canadian adoption by the CSA Technical Committee on Consumer and Commercial Products, under the jurisdiction of the CSA Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the Technical Committee. Due to the medical content of this Standard, it was also approved by the CSA Technical Committee on Application of Electricity in Health Care, under the jurisdiction of the CSA Strategic Steering Committee on Health and Well-being. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. 

Scope and object 

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-frequency ventilators or accessories which provide conventional ventilation for use in critical care environments, which are given in ISO 80601-2-12 [23];. 

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 ISO 80601-2-13 [24]; - ventilators or accessories intended for the emergency medical services environment, which are given in ISO 80601-2-84, the replacement for ISO 10651-3 [13]; 

NOTE 6 An HFV can incorporate EMS ventilator capability. - ventilators or accessories intended for ventilator-dependent patients in the home healthcare environment, which are given in ISO 80601-2-72 [26]; - ventilators or accessories intended for home-care ventilatory support devices, which are given in ISO 80601-2-79 [27] and ISO 80601-2-80 [28], the replacements for ISO 10651-6 [15]; - sleep apnoea breathing therapy ME equipment, which are given in ISO 80601-2-70 [25]; - bi-level positive airway pressure (bi-level PAP) ME equipment; - continuous positive airway pressure (CPAP) ME equipment; - respiratory high-flow ME equipment, which are given in ISO 80601-2-90:—1; and - 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 [39] and labelling [40] 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 of European regulation (EU) 2017/745 [38] as indicated in Annex FF.
