Abstract

The Venturi is a flow-accelerating injector, activated by fresh gas inflow from the anaesthetic machine. The Venturi entrains exhaled gas from the patient through a soda-lime canister, and carries it to the patient together with fresh gas. The Venturi circuit is a Mapleson D system and the fresh gas requirements are roughly 30 ml kg-1 min-1 for anaesthetized, relaxed, adult patients under controlled ventilation.

摘要

文丘里装置是一种流量加速注射器，由麻醉机的新鲜气体流入激活。文丘里装置通过一个钠石灰罐从患者那里吸入呼出气体，并将其与新鲜气体一起输送给患者。文丘里回路是一个马普leson D系统，对于在控制通气下的麻醉、松弛的成年患者，新鲜气体需求量约为30毫升/千克/分钟。
