title: Preliminary evaluation of the Enclosed Magill Breathing System.
abstract: The Enclosed Magill anaesthetic breathing system may be used for both spontaneous ventilation and controlled ventilation with similar fresh gas flows. During spontaneous ventilation, a fresh gas flow between estimated alveolar ventilation and minute ventilation is adequate and the system performs as a Mapleson A type breathing system. For controlled ventilation, a fresh gas flow of 70-100 ml kg-1 min-1 produces normocapnia in most subjects, as demonstrated in this limited study. These values are similar to those demonstrated for type D breathing systems. It is suggested from this preliminary study that the breathing system conforms to the requirements of a universal breathing system in as much as similar fresh gas flows are used in both modes of ventilation.
