This specification covers breathing systems and components employed with anesthesia gas machines for humans. This specification considers the circle system as a whole and some of its components individually. A particular emphasis is placed upon component arrangement in the circle absorber-type system, and submits a system of standard description and notation. Excluded are ventilators for use during anesthesia, Mapelson nonrebreathing type systems, as well as breathing systems and related components of dental analgesia machines.
Formerly under the jurisdiction of Committee F29 on Anesthetic and Respiratory Equipment, this specification was withdrawn in July 2014 in accordance with section 10.6.3 of the
This specification covers breathing systems and components employed with anesthesia gas machines for humans. This specification considers the circle system as a whole and some of its components individually. A particular emphasis is placed upon component arrangement in the circle absorber-type system, and submits a system of standard description and notation. The circle system is divided into four segments: segment 1 - from patient to expiratory valve, segment 2 - from expiratory valve to reservoir bag, segment 3 - from reservoir bag to inspiratory valve, and segment 4 - from inspiratory valve to patient. Leakage of breathing system and resistance of breathing system shall be tested to meet the requirements prescribed. The adjustable pressure-limiting valves, reservoir bag connectors and reservoir bags, carbon dioxide absorbers, unidirectional valves, and optional components shall meet the requirements prescribed.
