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.
随附的马吉尔麻醉呼吸系统可用于自主通气和控制通气，且新鲜气流相似。在自主通气期间，估计肺泡通气量和分钟通气量之间的新鲜气流就足够了，该系统作为马普leson A型呼吸系统发挥作用。对于控制通气，在这项有限的研究中表明，70 - 100 ml·kg⁻¹·min⁻¹的新鲜气流在大多数受试者中可产生正常碳酸血症。这些数值与D型呼吸系统所显示的数值相似。这项初步研究表明，该呼吸系统符合通用呼吸系统的要求，因为在两种通气模式中使用的新鲜气流相似。
