This document applies to the basic safety and essential performance of respiratory high-flow therapy equipment, as defined in 201.3.219, hereafter also referred to as ME equipment, in combination with its accessories:

— intended for use with patients who can breathe spontaneously; and

— intended for patients who would benefit from improved alveolar gas exchange; and who would benefit from receiving high-flow humidified respiratory gases, including a patient whose upper airway is bypassed.

EXAMPLE 1 Patients with Type 1 Respiratory Failure who exhibit a reduction in arterial blood oxygenation or patients who would benefit from reduced work of breathing, as needed in Type 2 Respiratory Failure, where arterial carbon dioxide is high.

Respiratory high-flow therapy equipment can be intended for use in the home healthcare environment or intended for use in professional healthcare facilities.

NOTE 1 In the home healthcare environment, the supply mains is often not reliable.

Respiratory high-flow therapy equipment can be transit-operable.

This document is also applicable to those accessories intended by their manufacturer to be connected to the respiratory high-flow therapy equipment, where the characteristics of those accessories can affect the basic safety or essential performance of the respiratory high-flow therapy equipment.

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, 7.2.13 and 8.4.1.

NOTE 2 Additional information can be found in IEC 60601-1:2005+AMD1:2012, 4.2.

This document does not specify the requirements for:

ventilators or accessories for ventilator-dependent patients intended for critical care applications, which are given in ISO 80601-2-12[15];

ventilators or accessories intended for anaesthetic applications, which are given in ISO 199 80601-2-13[16];

ventilators or accessories intended for the emergency medical services environment, which are given in ISO 80601-2-84[21]2;

ventilators or accessories intended for ventilator-dependent patients in the home healthcare environment, which are given in ISO 80601-2-72[18];

— ventilatory support equipment or accessories intended for patients with ventilatory impairment, which are given in ISO 80601-2-79[19];

— ventilatory support equipment or accessories intended for patients with ventilatory insufficiency, which are given in ISO 80601-2-80[20];

— sleep apnoea therapy ME equipment, which are given in ISO 80601-2-70[17];

— continuous positive airway pressure (CPAP) ME equipment;

— high-frequency jet ventilators (HFJVs)[32], which are given in ISO 80601-2-87[22];

— gas mixers for medical use, which are given in ISO 11195[11];

— high-frequency oscillatory ventilators (HFOVs), which are given in ISO 80601-2-87[22]; and

— cuirass or “iron-lung” ventilation equipment.

NOTE 3 Respiratory high-flow therapy equipment can be incorporated into any of the above equipment, in which case those standards would be applicable for those ventilation-modes.

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

This document applies to the basic safety and essential performance of a humidifier, also hereafter referred to as ME equipment, in combination with its accessories, the combination also hereafter referred to as ME system.

This document is also applicable to those accessories intended by their manufacturer to be connected to a humidifier where the characteristics of those accessories can affect the basic safety or essential performance of the humidifier.

EXAMPLE 1         Heated breathing tubes (heated-wire breathing tubes) or ME equipment intended to control these heated breathing tubes (heated breathing tube controllers).

NOTE 1        Heated breathing tubes and their controllers are ME equipment and are subject to the requirements of IEC 60601‑1.

NOTE 2        ISO 5367 specifies other safety and performance requirements for breathing tubes.

This document includes requirements for the different medical uses of humidification, such as invasive ventilation, non-invasive ventilation, nasal high-flow therapy, and obstructive sleep apnoea therapy, as well as humidification therapy for tracheostomy patients.

NOTE 3        A humidifier can be integrated into other equipment. When this is the case, the requirements of the other equipment also apply to the humidifier.

EXAMPLE 2         Heated humidifier incorporated into a critical care ventilator where ISO 80601‑2-1 also applies.

EXAMPLE 3         Heated humidifier incorporated into a homecare ventilator for dependent patients where ISO 80601‑2-72 also applies.

EXAMPLE 4         Heated humidifier incorporated into sleep apnoea therapy equipment where ISO 80601‑2‑70 also applies.

EXAMPLE 5         Heated humidifier incorporated into respiratory high-flow therapy equipment where ISO 80601‑2‑90 also applies.

This document also includes requirements for an active HME (heat and moisture exchanger), ME equipment which actively adds heat and moisture to increase the humidity level of the gas delivered from the HME to the patient. This document is not applicable to a passive HME, which returns a portion of the expired moisture and heat of the patient to the respiratory tract during inspiration without adding heat or moisture.

NOTE 4        ISO 9360‑1 and ISO 9360‑2 specify the safety and performance requirements for a passive HME.

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, 7.2.13 and 8.4.1.

NOTE 6        Additional information can be found in IEC 60601‑1:2005+AMD1:2012, 4.2.

This document does not specify the requirements for cold pass-over or cold bubble-through humidification devices, the requirements for which are given in ISO 20789.

This document is not applicable to equipment commonly referred to as “room humidifiers” or humidifiers used in heating, ventilation and air conditioning systems, or humidifiers incorporated into infant incubators.

This document is not applicable to nebulizers used for the delivery of drugs to patients.

NOTE 7        ISO 27427 specifies the safety and performance requirements for nebulizers.
