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;NOTE2 In the home healthcare environment, the supply mains driving the ventilatory support equipment is often not reliable.NOTE3 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.EXAMPLE1 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.This document is also applicable to those accessories intended by their manufacturer to be connected to the breathing system of ventilatory support equipment for ventilatory impairment, where the characteristics of those accessories can affect the basic safety or essential performance of the ventilatory support equipment for ventilatory impairment.EXAMPLE2 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 MEequipment only, or to MEsystems 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 MEequipment and to MEsystems, as relevant.Hazards inherent in the intended physiological function of MEequipment or MEsystems within the scope of this document are not covered by specific requirements in this document except in IEC60601‑1:2005+AMD1:2012+AMD2:2020, 7.2.13 and 8.4.1.NOTE4 Additional information can be found in IEC60601‑1:2005+AMD1:2012+AMD2:2020, 4.2.NOTE 5 See ISO/TR 21954 for guidance on the selection of the appropriate ventilator for a given patient. This document does not specify the requirements for:— ventilators or accessories for ventilator-dependent patients intended for critical care applications, which are given in ISO80601‑2‑12;— ventilators or accessories intended for anaesthetic applications, which are given in ISO80601‑2‑13;— ventilators or accessories intended for the emergency medical services environment, which are given in ISO80601‑2‑84;— ventilators or accessories intended for ventilator-dependent patients in the home healthcare environment, which are given in ISO80601‑2‑72;— ventilatory support equipment or accessories intended for ventilatory insufficiency, which are given in ISO80601‑2‑80;— sleep apnoea therapy MEequipment, which are given in ISO80601‑2‑70;— high-frequency jet ventilators (HFJVs), which are given in ISO80601‑2‑87;— high-frequency oscillatory ventilators (HFOVs);— respiratory high flow equipment, which are given in
