Medical gas pipeline systems - Part 3:Proportioning units for the production of synthetic medical air (ISO/DIS 7396-3:2023)

This standard applies to proportioning units intended to produce synthetic medical air and air for driving surgical tools by mixing in defined proportions oxygen and nitrogen.
This standard applies to proportioning units intended to be components of a medical gas supply system for medical air which supplies a medical gas pipeline distribution system complying with ISO 7396-1.
The number of proportioning units within the medical air supply system and their combination with other sources of supply (e.g. cylinder manifolds) to ensure that the supply system consists of at least three sources of supply is outside the scope of this standard. Requirements for the supply systems for medical air are given in ISO 7396-1.

SIST EN ISO 80601-2-12:2024

This document applies to the basic safety and essential performance of a critical care ventilator in combination with its accessories, hereafter referred to as ME equipment:
¾     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 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.
¾     intended to be operated by a healthcare professional operator; and
¾     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:
