At present, when economy and environment receive high priority, the ideal anaesthesia system with inhalation anaesthetics is a closed circle system in which only the gases which the patient consumes or produces are replaced or eliminated. Low-flow (LF) anaesthesia in which the fresh gas flow which is employed in a closed system, provides a stable system compares with closed anaesthesia systems. Compared with open systems and circler systems with considerable fresh gas flow, the LF system provides advantages as regards economy, environment and exposure of staff to inhalation anaesthetics. The special conditions involved in LF anaesthesia are described in detail with the hope that the method will obtain more widespread distribution than is the case in Denmark today. If greater safety under anaesthesia is desired, eg by monitoring the concentrations of CO2, O2 and inhalation anaesthetics which the patients inspire and expire, this monitoring equipment can be financed by introduction of LF anaesthesia.
目前，在经济和环境备受关注的当下，理想的吸入麻醉剂麻醉系统是一个闭环系统，其中仅替换或消除患者消耗或产生的气体。低流量（LF）麻醉是在封闭系统中使用新鲜气体流量，与封闭麻醉系统相比，它能提供一个稳定的系统。与开放系统和具有相当大新鲜气体流量的循环系统相比，LF系统在经济、环境以及工作人员接触吸入麻醉剂方面具有优势。本文详细描述了LF麻醉所涉及的特殊情况，希望该方法能比目前在丹麦更广泛地应用。如果希望在麻醉过程中提高安全性，例如通过监测患者吸入和呼出的二氧化碳、氧气以及吸入麻醉剂的浓度，这种监测设备可以通过引入LF麻醉来提供资金支持。
