AbstractAt 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.
