Medical electrical equipment - Part 2-70: Particular requirements for the basic safety and essential performance of sleep apnoea breathing therapy equipment

This document is applicable to the basic safety and essential performance of sleep apnoea breathing therapy equipment, hereafter referred to as ME equipment, intended to alleviate the symptoms of patients who suffer from obstructive sleep apnoea by delivering a therapeutic breathing pressure to the respiratory tract of the patient. Sleep apnoea breathing therapy equipment is intended for use in the home healthcare environment by lay operators as well as in professional healthcare institutions. * Sleep apnoea breathing therapy equipment is not considered to utilize a physiologic closed-loop-control system unless it uses a physiological patient variable to adjust the therapy settings. This document excludes sleep apnoea breathing therapy equipment intended for use with neonates. This document is applicable to ME equipment or an ME system intended for those patients who are not dependent on mechanical ventilation. This document is not applicable to ME equipment or an ME system intended for those patients who are dependent on mechanical ventilation such as patients with central sleep apnoea. This document is also applicable to those accessories intended by their manufacturer to be connected to sleep apnoea breathing therapy equipment, where the characteristics of those accessories can affect the basic safety or essential performance of the sleep apnoea breathing therapy equipment. Masks and application accessories intended for use during sleep apnoea breathing therapy are additionally addressed by ISO 17510. Refer to Figure AA.1 for items covered further under this document. 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 the general standard. NOTE See also 4.2 of the general standard. This document is not applicable to high-frequency jet ventilators (HFJVs) or high-frequency oscillatory ventilators (HFOVs), which are given in ISO 80601-2-87[13]. This document does not specify the requirements for ventilators or accessories intended for critical care ventilators for ventilator-dependent patients, which are given in ISO 80601‑2‑12. This document does not specify the requirements for ventilators or accessories intended for anaesthetic applications, which are given in ISO 80601-2-13[8]. This document does not specify the requirements for ventilators or accessories intended for home care ventilators for ventilator-dependent patients, which are given in ISO 80601-2-72[9].

NOTE 1 There is guidance or rationale for this subclause contained in Clause AA.2.
This document applies to the basic safety and essential performance of ventilatory support equipment, as defined in 201.3.302, for ventilatory impairment, as defined in 201.3.300, hereafter also referred to as ME equipment, in combination with its accessories:
- intended for use in the home healthcare environment;
NOTE 2 In the home healthcare environment, the supply mains driving the ventilatory support equipment is often not reliable.
NOTE 3 Such ventilatory support equipment can also be used in professional health care facilities.
- intended for use by a lay operator;
- intended for use with patients who have ventilatory impairment, the most fragile of these patients, would not likely experience injury with the loss of this artificial ventilation; and
- not intended for patients who are dependent on artificial ventilation for their immediate life support.
EXAMPLE 1 Patients with mild to moderate chronic obstructive pulmonary disease (COPD).
Ventilatory support equipment is not considered to use a physiologic closed-loop control system unless it uses a physiological patient variable to adjust the artificial ventilation therapy settings.

EXAMPLE 2 Breathing sets, connectors, water traps, expiratory valve, humidifier, breathing system filter, external electrical power source, distributed alarm system.
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 IEC 60601‑1:2005+AMD1:2012+AMD2:2020, 7.2.13 and 8.4.1.
NOTE 4 Additional information can be found in IEC 60601‑1:2005+AMD1:2012+AMD2:2020, 4.2.

Small-bore connectors for liquids and gases in healthcare applications - Part 2: Connectors for respiratory applications

This document specifies the design and dimensions for two small-bore connectors intended to be used for connections in respiratory applications of medical devices and accessories. One connector (R1) is intended for use on medical devices and accessories subjected to pressures up to 15 kPa (e.g. a breathing system). The other connector (R2) is intended for use on medical devices and accessories subjected to higher pressures between 15 kPa and 600 kPa (e.g. oxygen therapy tubing).
NOTE 1 The pressure is related to pressure available at the source to which the medical device is connected.
NOTE 2 The intended application does not preclude the use of other connectors on medical devices or accessories within this application.
NOTE 3 Requirements for alternative connectors for this intended application are specified in ISO 80369-1.
This document does not specify requirements for the medical devices or accessories that use these connectors. Such requirements are given in device-specific standards.
NOTE 4 If a device-specific standard does not exist, the performance and material requirements specified in ISO 80369-1 can be used as guidance.

NOTE 2 For the purposes of this document, such an environment is referred to as a critical care environment. Ventilators for this environment are considered life-sustaining.
NOTE 3 For the purposes of this document, such a critical care ventilator can provide ventilation during transport within a professional healthcare facility (i.e. be a transit-operable ventilator).
NOTE 4 A critical care ventilator intended for use in transport within a professional healthcare facility is not considered as an emergency medical services environment ventilator.
- intended to be operated by a healthcare professional operator; and
- intended for those patients who need differing levels of support from artificial ventilation including for ventilator-dependent patients.
A critical care ventilator is not considered to use a physiologic closed-loop-control system unless it uses a physiological patient variable to adjust the artificial ventilation therapy settings.
This document is also applicable to those accessories intended by their manufacturer to be connected to a ventilator breathing system, or to a ventilator, where the characteristics of those accessories can affect the basic safety or essential performance of the ventilator.
NOTE 5 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 IEC 60601-1:2005+AMD1:2012+AMD2:2020, 7.2.13 and 8.4.1.
NOTE 6 Additional information can be found in IEC 60601-1:2005+AMD1:2012+AMD2:2020, 4.2.
This document is not applicable to ME equipment or an ME system operating in a ventilator-operational mode solely intended for patients who are not dependent on artificial ventilation.
NOTE 7 A critical care ventilator, when operating in such a ventilator-operational mode, is not considered life-sustaining.
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:
