When compared to the circle system alternative breathing systems (ABS) are of no benefit. When the only indication of an ABS is emergency oxygen administration it should be connected to the O2 pipeline upstream from the flowmeter bank and the vaporiser. The use of an ABS for anaesthesia maintenance is no longer justified because of the difficulties in monitoring pressure, flow and concentrations of the gas mixture, the cost of gas and vapour administered at a high flow and the resulting pollution. The use of an ABS for very short anaesthetics is only acceptable if the administered gas mixture is monitored.
与循环系统相比，其他呼吸回路（ABS）并无益处。当ABS的唯一用途是紧急给氧时，应将其连接到流量计组和蒸发器上游的氧气管道。由于监测气体混合物的压力、流量和浓度存在困难，高流量给药时气体和蒸汽的成本以及由此产生的污染，使用ABS进行麻醉维持已不再合理。仅在监测所输送气体混合物的情况下，才可以接受将ABS用于极短时间的麻醉。
