ISO 80601-2-55:2018 specifies particular requirements for the basic safety and essential performance of a respiratory gas monitor (rgm), hereafter referred to as me equipment, intended for continuous operation for use with a patient. ISO 80601-2-55:2018 specifies requirements for - anaesthetic gas monitoring, - carbon dioxide monitoring, and - oxygen monitoring. NOTE 1 An rgm can be either stand-alone me equipment or integrated into other equipment, e.g. an anaesthetic workstation or a ventilator.
